Which TeraFlex lift kit is best for my Jeep? Why do you offer so many lift kits?
We get these types of questions all the time here at TeraFlex. And the simple answer is:
Well, it depends.
It depends on what you want out of your JK Wrangler/Unlimited.
Do you use your Jeep as a commuter or family car? Is it a hardcore weekend warrior? Or is it a dual-purpose rig used for daily driving as well as escaping city life and paved streets? The tire diameter you want to run also dictates what size lift you will need. Cost is also a factor.
All these questions must be taken into consideration when choosing a lift kit.
Bigger isn’t always better. But sometimes bigger is better. And that’s why we offer a variety of suspension systems from mild to wild — and several in between — so our customers can find the configuration for their rig that’s best suited to their needs.
