What is a Johnny Joint and why is it important for this trac bar?

A Johnny Joint is a high-angle, self-centering spherical bearing that allows for a lot of movement. For this trac bar, it means your rear suspension can articulate more freely over rough terrain without binding, which helps maintain tire contact and stability.

What does DOM tubing mean for this trac bar?

DOM stands for Drawn Over Mandrel. This manufacturing process creates a strong, seamless tube with consistent wall thickness. It's a durable material choice for off-road components that need to handle stress and impacts.

What else might I need to install this kit?

This kit includes the trac bar and all necessary hardware. However, depending on your specific Jeep's setup and any existing modifications, you may want to have basic hand tools, a torque wrench, and potentially penetrating oil on hand for installation. Always refer to the manufacturer's instructions for the most accurate guidance.

Product Details

This is the RockJock rear Johnny Joint Trac Bar kit for your Jeep TJ or LJ. It's designed to give you better control over your rear axle, especially when you're off-roading or dealing with uneven terrain. A well-functioning trac bar is key to keeping your rear axle centered under the vehicle and preventing that annoying side-to-side wander you can sometimes feel in the steering, particularly after lifting your Jeep.

What sets this kit apart is the use of a genuine Johnny Joint, a popular and well-regarded component in the off-road world. This joint allows for a significant amount of articulation, meaning your suspension can move freely without binding, which is crucial for maintaining traction on rough trails. The main bar itself is constructed from 1.25-inch DOM (Drawn Over Mandrel) tubing. DOM tubing is known for its strength and durability, making it a solid choice for off-road components that need to withstand abuse. This kit includes all the necessary hardware for installation, so you should have everything you need to get it bolted on and ready to perform.

When you're installing this, pay close attention to the manufacturer's instructions for proper alignment and mounting. Getting the trac bar set up correctly is important for both handling and tire wear. This kit is a substantial upgrade for anyone looking to improve the rear suspension performance and stability of their TJ or LJ, particularly those who have modified their suspension with a lift kit.
