Mark Falkner
President, Founder and Owner of TeraFlex

Click here to get the full scoop.

Mark was born in Salt Lake City, UT and grew up in a family of 10 kids. His Father started the company MEPCO (Military Equipment Parts Company) which bought and sold Jeep/Truck related military surplus and Mark began working in the yard at age 9, and then in high school he worked at ‘Jeep Joint’ repairing and restoring Jeeps in the evenings. Throughout those years he collected and sorted through old auctioned Jeep parts in the yard, traded with other shops around the country, and learned to assemble his own builds with his brother. As Mark made terrific memories of fun, he also gained a significant amount of learning and experience though trial and error. In 1982 Mark left Mepco to manage a Chevrolet service dept., and five years later he returned and purchased Mepco from his father who then retired. In 1996 the TJ Wrangler came out, opening an immediate demand for a lift kit which did not yet exist. Mark developed the first TJ Wrangler Lift Kit in the world and started the brand new company TeraFlex, which would focus solely on development and manufacturing of parts and suspensions for the Jeep Wrangler. This skilled, humble and hard worker has created a legacy of quality and success and continues to push it forward today by maintaining the big picture. Other hobbies Mark enjoys are fishing, family, and church. He and his wife Sid are empty nesters, with six children and sixteen grandchildren.

My favorite thing about Jeeping is that it can be a wholesome family activity that exposes people to all the natural wonders and earth’s beauty. We live in an amazing region of the country; Jeeps help us explore without fear of getting stranded.



Vinson Pratt
Marketing Director

Vinny was born and raised in Salt Lake City, Utah. He works hard long hours to maintain organization and outstanding quality among TeraFlex’s marketing and promotional efforts. Vinny’s journey into the Jeep life began in 1990 with a trip to Blanding, UT to visit extended family. Uncle Ed owned an old CJ-7, and his walls displayed photos of him in Moab, defying gravity as he drove straight up some rock formations. Soon Vinny was riding shotgun in that CJ-7, topless and doorless. It was love at first ride. Big dreams were born and came to pass years later on February 1st 2000 when Vinny began part-time in TeraFlex’s production department to help pay for college. He bought his first Jeep that September – a rolled 1998 TJ. He fixed her up, ran her everywhere, rolled and fixed her up again and continued giving her love until he finally upgraded years later to a 2009 Rubicon Unlimited. Today he rides a 2016 JKU and owns a 1948 CJ-2a of his own as a long-term garage project. Vinny enjoys road and mountain biking, running, and air-cooled VW’s. He lives in West Valley, UT with his wife of 13 years, 2 daughters and a tiny dog named Bob.

I really enjoy the freedom that Jeeping gives me. I am able to find some of the most remote roads and trails and escape for hours. Over the years my driving style has transitioned into that of a quiet and solitary explorer. The days of proving my ego and abilities have passed and have been replaced by the enjoyment of truly finding the road less traveled. The dependable TeraFlex components give me the peace of mind to know that I will make it out and back.



Ben Falkner
Operations Manager / Research and Development

Ben has lived in Utah for all but 2 years of his life. Ben is the guy who answers questions from customer service, helps solve problems with getting product out the door, resolves any issues that come up from Quality Control and does all he can to improve the Research and Development Program. Like his father and siblings, the Jeep industry is in his blood. Favorite memories include Jeeping all over the Manti, Utah mountains and building Jeeps with his father, who kept him included working at his side. Ben began working for his Dad at Mepco at 8 years old. At age 14 he worked instead for CRW Automotive/4 Plus Mfg. where he earned more money needed to fund his CJ7 project. At age 15 he quit and sought out work for more hours, took other jobs and visited Mepco to work as often as possible. Ben began work at TeraFlex as soon as the owner would allow it and has been here ever since, aside from 2 years spent in voluntary service for his church. Other activities he enjoys with his family include mountain biking, BMX racing, dirt biking, hiking and camping. Ben currently lives in Sandy, UT with his wife and four children.

My favorite thing about Jeeping is spending time with family and friends. I have especially loved watching my wife develop into a confident driver and I look forward to my children learning how to drive and overcome obstacles. My second favorite thing is building them … even more than I love driving them. I love the challenge of coming up with an idea and making it. Even the ideas that don’t work out have been good learning experiences.



Adam Spendlove
Research & Development/ Prototype & Testing Technician

After being raised in St. George, UT, working several jobs in the automotive world, finding interest in off-road vehicles and attending school of automotive technology at WyoTech, it is no surprise that Adam found a career with TeraFlex Suspensions in 2011. Today, the company fleet is his baby – Adam makes sure the Jeeps are built, maintained and tested. Adam first entered the off-road life in 2001 when he bought his first 4x4, a Chevy truck. He eventually grew tired of the truck’s limitations and purchased a 1999 Jeep Cherokee in 2008 with his brother. They slowly built it up until it handled quite well on and off-road, but it had become more expensive than it was worth. In 2013, Adam began driving the 2 door Green Gecko JK. Other activities Adam enjoys are downhill mountain biking, dirt biking, camping, and going to the lake. Ladies, keep an eye out on the trails because this master technician is also single.

I love seeing new places that are hard to get to and seen by few. Jeeps are a fun way to get down the road less traveled. As a child, my dad and grandfather helped me see how much beauty there is in the world that few people take the opportunity to appreciate. Unfortunately, in those days it involved a lot more hiking than I prefer. Having a Jeep gives me more excuse to go camping and get outdoors than I would take the time for otherwise.



Doug Henderson
Customer Service Representative

Doug grew up in Whittier, CA and moved to UT in 1975. Doug is known for taking special care in helping TeraFlex’s customers with their questions and needs. Although Doug specializes in all Jeep makes and models, drive trains and the older Jeep models would be his main specialty. Doug bought his first Jeep in 1985 – a 1963 CJ-5. This is where the Jeep fever struck. In 1987 he sold the CJ-5 and bought a 1982 CJ-7 and six years later he opened his own business “Doug’s Off Road.” He maintained that business until 1991 he closed the doors and began working at advanced 4Wheel Drive before finding Mepco Jeep Supply one year later. He stayed there five years before venturing out on his own again working at four different shops. Doug returned and started working for TeraFlex in 2007 and has been here ever since. Aside from taking his 2015 JK “Tank” on off-road adventures, he also enjoys shooting, hiking, gardening and bird watching. He lives in Kearns, UT with his wife who works in TeraFlex’s shipping dept. He has two adult kids, one step-daughter and two grandchildren.

I like Jeeping because it gets me away from it all. My favorite place to go is The Needles District in Canyonlands National Park.



Mark Burrup
Dearler Account & Customer Service Representative

Mark grew up in Salt Lake City, UT. His is another friendly voice you may have spoken with on the phone to discuss questions about your Jeep. Mark drives the famous “Fire Engine Jeep,” which signifies his other part-time job as a fire fighter/EMT. Growing up, Mark loved cars. He raced Go-Karts, street raced, and started his automotive career at age 16 working at Discount Tire. He soon performed his first engine swap one year later in a Toyota Supra. At age 18 he bought a 1985 GMC 1500, lifted it, added 32” mud terrains and started exploring the off-road world. He believed his truck was unstoppable until he split the T-case in two. Enter Mark’s first Jeep. Approximately three XJs and five MJs later he purchased his first TJ Wrangler. He build it up, rode it hard and sold it like the rest. Today he’s riding his 2015 JK and couldn’t be happier as he’s working his sixth year at TeraFlex, surrounded by Jeeps and fellow off-roaders alike. Mark also enjoys dirt biking, camping, photography, hiking and most any outdoor related activity. He enjoys working on cars, and building and fixing things. Today he lives in Taylorsville, UT and ladies this man is still single!

I enjoy the places Jeeping can take me on the top of the mountains, and the quality time spent with friends and family as we ride along the dusty trails. I also enjoy the adrenaline rush that off-roading and rock crawling can provide.



Corbin Black
Axle Department Manager, specialized in MIG welding

This Monticello, UT raised man cuts, machines and welds four to six axles per day with his crew, and also builds a handful of various parts for other TeraFlex departments. As a kid, Corbin’s folks drove a 1960’s Tuxedo Park Edition CJ5 all over the Blue Mountains of San Juan County, UT. At 16 yrs old, Corbin purchased his first vehicle – a ‘98 TJ Sport and his first modification process began. He later attend Utah State University’s Eastern Campus in Price, UT to study welding. At that time Corbin was building a 2004 Jeep Grand Cherokee and performed his first axle swap in his driveway with axles out of a 2011 Jeep Rubicon. Soon after, he started his first job as a welder at TeraFlex. Corbin now lives in West Jordan, UT with his wife except when he’s working hard with the Utah Army National Guard, with whom he recently returned from deployment to the Middle East. Corbin enjoys anything and everything outdoors form hunting (archery and rifle), golf, boating, hiking, biking, etc. He is currently rebuilding a wrecked 2009 Harley Davidson Street Glide and a ‘78 Stratus fishing boat in his spare time.

My favorite thing about Jeeping is the ability to modify the Wrangler to each individual. There are so many ways to build a Wrangler to fit anyone’s lifestyle and let’s face it, who doesn’t love a convertible? Over the past few years, my Jeep has been my daily driver and was used for everything including wheeling, camping, hunting, trips to the grocery store and even the mall. Now that I bought a truck for my new daily driver, I have big modification plans and the Jeep will be used mostly for wheeling and camping.



Greg Buckway
Quality Control Manager

Originally from TeraFlex’s current residence, West Jordan UT, Greg specializes in developing and implementing strategies that focus on continual improvement among the entire TeraFlex system. He analyzes people, processes and products to ensure that the customer receives what they want in the way they expect it. He seeks to progressively develop each supply chain interaction so that our products are as cost-effective at high quality as possible. Greg was personally introduced to the Jeep and off-road lifestyle by his wife. They met and went off-roading his first time in 2008, and he immediately felt enormous respect for Jeeps and the industry. This led him to six years of passionate service under the TeraFlex name. Greg received his undergraduate degree in 2007 and got accepted into law school when he met his wife and fell in love with Jeeps. He began working for TeraFlex in 2009 and changed gears from law to a Master’s of Business Administration, emphasizing in Strategic Management to become a greater asset to the company. Other activities Greg enjoys include golfing and tennis, but mostly spends time with the family and taking the kids on Jeep rides. He lives in South Jordan, UT with his wife Mindy and three beautiful girls.

My favorite thing about Jeeping comes right after completing a huge obstacle; in that moment I realize that, much like a Jeep on the trail, I am capable of doing pretty amazing things with my life. I only need to push past my fears to recognize my true potential.
Being a Jeep owner has enabled my family to better connect with nature. We’ve traveled the outdoors, over rocks and through rivers, to see some of the most beautiful views this planet has to offer. What’s more, we’ve been able to share this lifestyle with friends and family and create experiences together that we’ll never forget.



Brady Ralph
Customer Service Rep., International Business

Born and raised only a few miles south of TeraFlex’s current location, Brady and his passion for Jeeps grew in South Jordan, UT. Brady spends his days helping Jeepers on the phones and managing TeraFlex's international dealer network. As a kid, it was his brother’s XJ that sparked his first interest in the Jeep life. “He took me wheeling for the first time and that was it. I was hooked.” Brady immediately started saving and bought his 2007 JKU Rubicon that he still drives and “absolutely loves.” Brady has spent two years at Utah Valley University and almost has his AS degree in Mechanical Engineering Technology from SLCC, after which he’ll move on to the University of Utah to complete his BS degree in Mechanical Engineering with an emphasis in Aerospace Engineering. This single bloke still lives in South Jordan, UT and also enjoys mountain biking, hiking, snowboarding and camping.

Plain and simple: A day Jeeping on the trails surrounded by good friends… does it get any better than that? I don’t think so.
