Overview
The TeraFlex Elite LCG Long Arm Upgrade Kit, part 1457000, is a set of upper and lower long FlexArms for the front and rear of the 2007–2015 Jeep Wrangler JK. Long FlexArms let the installer set pinion and caster angles for alignment and keep the axle located in the wheel well as the suspension moves.
The kit suits JK owners who want the long arm version of the FlexArm system. The JK Long Arm Brackets, part 1957000, complete the Elite LCG kit, so plan on that part as well. Because the arms are longer than the standard set, check alignment and driveline angles after installation.
Key features

- Adjustable pinion and caster angles for alignment
- Keeps the axle located in the wheel well during suspension travel
- Frame brackets listed in the highlights
- Hardware listed in the highlights
- Designed for the 2007–2015 Jeep Wrangler JK
Long arm considerations
Long FlexArms change the leverage on the axle, so they respond more to small angle changes than shorter arms do. A long arm setup can make steering and tire wear feel different until the angles are reset. Plan the install around an alignment appointment, and bring the vehicle with the brackets already mounted so the shop can set angles with the parts in their final position.
Brackets and hardware are the part of a long arm kit that most often gets set aside. Before ordering, confirm the frame brackets, hardware and companion brackets will all be on hand, and sort them by position before starting. Long arms carry more load through the mounts, so inspect the frame mounting points and fasteners at each service and after rough trail use.
- Sort brackets and hardware by position
- Inspect frame mounts after rough trail use
- Schedule alignment with brackets installed

Models outside the JK, such as the TJ, LJ, JL and Gladiator, are not on the list. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The arms set pinion and caster, so have an alignment shop set those angles after the arms are in. On a lifted JK, check driveline angles once the kit is installed, and keep the vehicle on stands whenever work is done underneath it.
