Frequently Asked Questions
Q: I just installed my lift and now my Jeep is leaning to the passenger side.
This is a common occurrence on all Jeeps. In fact, the new JK Wrangler has adapted the terminology “JK lean.” The causation of this lean is due to the fact that the spare tire weight as well as the gas tank weight is predominantly held on the passenger (right hand side) of the Jeep, making it lean this way. You may even notice that the lean gets better or worse depending on how much fuel is in the gas tank. The lean is a natural occurrence and even happens on stock Jeeps, we just fail to notice because the straight line reference of the bumper blends in better with the axle and the shadows of a stock Jeep. The lean can be helped by placing a ½” leveling spacer in the right rear corner. Be advised that when the Jeep is low on fuel this corner may stick up higher than the rest.
Q: I have had my lift a few months and it looks like my rear end is sagging / I measured from the fender flare to the center of the wheel and my jeep is sagging in the rear.
These are actually one in the same question. The cause stems from the fact that Jeep installed the rear flares on different planes, as well as made the rear flare opening smaller so it looks tighter. The proper way to measure a Jeep’s ride height is to measure from the ground up to the frame’s section between the wheels that is flat and parallel to the ground. Expect a slight variance front to back as the Jeep’s weight distribution isn’t even from side to side, due to the gas tank being on the right hand side.
Q: Does TeraFlex offer shocks for the Leveling Kits?
We do not, the Leveling kit uses a stock shock or stock-length aftermarket shock.
Q: Do your spring kits level the Jeep as well as lift?
Yes, we designed the spring kits to bring up the nose of the Jeep as well as lift the Jeep to help get rid of the nose down look of a stock Jeep.
Q: Do I need an alignment after installing this kit?
If you aren't changing the arms or track bar (Regardless of the lift height) the only thing that can be adjusted is the steering wheel, which does not require an alignment. The toe COULD be adjusted but it is not altered by lift height.
Q: Should I go with a 2.5” lift or the 3” lift? Ultimately, I want to run a 35" tire, and go wheeling at Rausch Creek in PA. Are the extra parts in a 3” kit really needed? Aside from the additional 0.5" of clearance, is there any real advantage to the 3" lift vs. the 2.5"? Also, If I go with the 3” lift, would I need all 8 arms?
The 3" lift will actually sit about 1" higher due to the changing of the springs, so you gain a little more clearance there. Now it all depends on what size tire you want to run. With 35's as the ultimate goal I would steer you towards a 3" lift. Rausch requires a fair amount of articulation on most trails and a 2.5" lift with stock fenders and 35's would rub. The 2.5" kits come with drop brackets for the rear brakes lines, while the 3" lift and above will really need control arms to correct pinion and castor angles, and to help steering and death wobble causes. With 35’s you only need the front lowers and rear uppers, so just 4 arms. We have a kit with those in it. Another item to consider is the front monster track bar. It is not a requirement, but a really nice upgrade as it lets you center the axle and it stiffens the over center steering feel. The kit #1256220 includes the 3" kit, 4 arms, shocks and track bar for a 4 door JK. Talk to your favorite dealer for the best pricing.
Now, you could run a 2.5" lift and get the tire clearance you need, but with the uneven glacier flows at RC, a little extra belly clearance is never a bad thing. However, if the budget is the primary concern, then I'd rock a 2.5" lift with trimmed factory fenders and recognize that the belly might get beat up, so some armor would be a good investment. Just remember that the more weight you add, the lower the jeep will sit, so there will be a balancing act if you choose to go with a 2.5" lift.
Q: How much lift does the TeraFlex 2.5” Spring Kit provide?
Based on stock bumpers, you should expect 3” inches in the front and 2.25” inches in the rear.
Q: What other components do I need when installing a 2.5” lift?
No extra parts are required unless you have a 2012 or newer JK and plan on adding an aftermarket shock other than TeraFlex. Otherwise, the Exhaust Spacer Kit #261000 is required. If 35” tires are installed we do recommend the HD Front Adjustable Track Bar #1753418.
Q: Do you need the Exhaust Spacer Kit when installing the 2.5” TeraFlex lifts?
The Exhaust Spacer Kit is not required when the TeraFlex 2.5” 9550 series shocks are used or the TeraFlex shock extensions. When an aftermarket shock is used, such as our optional Fox Racing shock, then the Exhaust Spacer #2610000 is required.
3” – 4” LIFT
Q: On a TeraFlex 3” Lift, are Adjustable Control Arms and an Adjustable Front Track Bar required?
Yes, they are necessary to correct geometry created from the increased lift angles.
Q: Do I need the Drag Link Flip with a 3” lift?
No, the Drag Link Flip is beneficial with 4” of lift or more.
Q: Can I change the springs to go from a 2.5" lift to 3.5" or 4.5" lift?
Changing lift height without addressing other suspension components can cause geometry complications, alignment problems , and many other drivability issues. Making sure that the correct shocks, control arms, bump stops, brake lines, and many other components are installed, is required for different lift heights. This will ensure a safe and enjoyable experience. If you think you are experiencing these issues, please call us for advice (801) 713-3314
Q: I live on the coast, and I've had other manufactures’ shocks and rust is a big issue. The Falcons look nice, but how do they hold up to rust?
The Falcon shocks are made of 6061 hard anodized aluminum and will resist corrosion and wear better than anything on the market today. They will stay as pretty as you are!... and you are B. E. A…utiful!
Q: Can I buy just the rear Falcon Tow/Haul shocks?
Shocks that were designed and tuned for an all 4 setup are not sold as and should not be used as a front or rear pair. Without the added damping from the complete set, undesirable, uncomfortable, or even dangerous vehicle handling characteristics may occur.
Q: How much adjustment does the Falcon 2.2 steering stabilizer have?
The Falcon 2.2 Fast Adjust EF stabilizer has 3 postions: soft, medium, and hard.
Q: Will the Falcon shocks make my Jeep fly?
Depending on what kind of altitude you are looking for. The falcon shock will definitely make you SOAR over the whoops and bumps and any trail you put in front of you.
Q: Will the TeraFlex 9550 VSS Steering Stabilizer fit with the factory hardware?
Yes, the TeraFlex 9550 Steering Stabilizer will install with the Jeep’s factory hardware. TeraFlex includes the correct sleeve in the kit to work with the factory bolt.
Q: Are your ball joints adjustable? What do they adjust and how do you adjust them?
TeraFlex HD Ball Joints are adjustable for wear, in the event of a loss of preload (not adjustable for camber or caster). By removing the 3 set screws and using the supplied spanner wrench, the lower half of the ball joint housing can be adjusted to the recommended specification of 70 in-lbs (about 6 ft. lbs). This pushes the ball back into the hardened wear plate to restore the preload and eliminate any movement caused by normal wear.
Q: Can I buy directly from you?
YES! You sure can. You can either place an order on our website or give us a call at 801-713-3314!
Q: Can Adjustable Control Arms and an Adjustable Front Track Bars be installed after a lift is installed?
Yes they can.
Q: Does the rubber bushing end or the flex end of the control arm go toward the frame?
The rubber bushing end goes to the frame.
Q: What do I do if my sway bar links are too small to fit on the stud mounted on my axle?
If you have a metal sleeve in the bushing it needs to be removed and discarded. Push the center metal sleeve out from the sway bar link mounting on the axle end.
Q: I am installing your sway bar links and they are just spinning.
This can be a common problem if the nut is not put on with an impact gun. For this reason the engineers designed a spot to hold the stud with an allen wrench in the end of the stud.
Q: I am trying to install shocks and the shaft is just spinning when I try and tighten the nut.
Place some electrical tape around a pair of lock pliers, such as vise grips. Once the tape is applied you can lock the pliers onto the shock shaft and use that to hold the shaft in place.
Q: Can you use a TJ rear seat with the TeraFlex Third-Row Seat Bracket?
No, the Third-Row Seat Bracket Kit requires a factory 2007-2015 JK 2 door rear seat, and only a factory JK 2 door rear seat.
Q: Do you offer military discounts?
Yes we do! Please give us a call at 801-713-3314 and we will be able to apply a 10% discount to your order.
Q: I bought this Jeep and it has your lift, how do I tell what size lift it has?
First, inspect the coil spring for part numbers. All TeraFlex coil springs are marked with a 7-digit part number.
Second, if the part number is not visible, due to road debris etc., take a measurement of a front and rear coil spring on the same side of the vehicle. Measurements should be taken from the underside of the upper coil bucket, down to the spring perch where it seats (This may vary slightly from added vehicle weight)
Once the part numbers and/or coil spring measurements have been gathered, please call our team of experts at (801) 713-3314. Be prepared to give us details about your specific vehicle application. We are happy to help!
