Introduction
This guide will walk through the correct installation procedure for the Grimm OffRoad JK Lower Control Arm/Track Bar Hardware Upgrade Kit.
Consumer Warning
All Grimm OffRoad products must be installed by a competent and qualified individual in accordance with the installation instructions intended for the product. Incorrectly installed products will void any warranties and may result in damage to the product or damage to the vehicle it was installed on. Read any provided instructions or guides and watch any available videos before attempting installation. If there are any questions, please contact Grimm OffRoad before starting installation.
Many products require the vehicle be properly raised and supported off the ground. The installer is responsible for confirming that this may be done in a safe manner and the correct equipment is available to perform the installation. Grimm OffRoad installation instructions assume the installer is able to properly and safely lift the vehicle.
Vehicles that have been modified will not perform the same as a stock vehicle. It is incumbent upon the owner of the vehicle to be aware of the differences the modifications will make to the driving characteristics of the vehicle. These may include (but are not limited to): changes in handling, braking, rollover angle, incompatibilities with the factory anti-lock braking systems, stability control systems, or traction control systems.
Tools
-
-
Verify that all parts shown in the picture are present.
-
-
-
This hardware kit should be installed with the vehicle on the ground resting on its own weight and is easiest with the wheels/tires removed.
-
We recommend placing the front and rear axles on jack stands and removing the wheels/tires.
-
When replacing the stock hardware with the hardware included in this kit, changing one piece at a time will make the job easier by keeping the axles in alignment.
-
If any bolts do not line up or are difficult to get in, a ratchet strap may be used to pull the components back into alignment. If you left the wheels and tires on and the vehicle is sitting on the ground, having a helper turn the steering wheel or push on the side of the Jeep can help align the components.
-
An impact wrench will make this job easier, but a breaker bar can be used as well.
-
If the Jeep has stock control arms/track bars or components that use stock-style Clevite bushings, the bolts must be torqued at ride height. If any components use free-spinning aftermarket bushings, they may be torqued at any height but it is generally best practice to torque at ride height.

With any modified vehicle, or any vehicle used offroad, it is a good idea to check bolt torques periodically and visually inspect components regularly.
