Overview
The TeraFlex 1257600 is a 6 inch Elite LCG long arm lift kit with shocks, for two-door and four-door 2007–2015 Jeep Wrangler (JK) models. It is designed to fit tires up to 38 inches and requires aftermarket wheels with 4.5 inch backspacing or less.
The kit uses fully adjustable upper and lower long FlexArms, which allow the pinion, caster and tire position to be modified. The adjustment range allows the suspension to be tuned to specific driving styles and handling preferences. Lower FlexArms are 2 inch OD by .281 wall DOM tube, with welded heavy duty bushing eyelets.
The design addresses anti-dive for braking, anti-squat for power transfer, and improvements to the front and rear roll centers. The kit also includes front sway bar disconnects. Drive shaft modifications are required with this suspension system.

Long arm geometry and tuning
Long arm systems change the way the axle travels, which is why they are often chosen for high ride heights and articulation. Adjustable FlexArms let the installer set pinion angle, caster and tire position, so the setup can be tuned to match how the vehicle is driven. Small changes to these settings can affect steering feel, braking and tire wear, so each adjustment should be checked on a test drive.
Bracketry is a big part of the job. Heavy duty brackets need solid welds, and the fit against the frame locating holes should be confirmed before the final welds are made. Recheck the shock mounts and bushings after the first few trips, and inspect the tubes and welds periodically. Drive shaft modifications are required with this system, so plan for them before the first trail run.
- Set pinion and caster in small steps
- Confirm bracket fit before final welds
- Inspect welds and bushings after the first trips
