Tie Rod Type

This setup is built for a JL or JT diesel that actually gets used.

The XDR Cylinder Assist gear paired with the DDS® stabilizer takes the sharp hits and wandering out of the steering so the wheel stays settled, even when the front end is loaded and working. The diesel-specific EHPS pump and cooling package keep everything consistent instead of fading off when temperatures come up.

This system is designed to fix the twitchy, harsh steering feel that shows up after lifting a Jeep or running larger tires. It brings the front end under control, makes the Jeep track straighter, and takes a lot of the effort out of driving.

DDS also adds steering torque when you need it, making it easier to turn bigger tires in tight, technical situations. On long drives, it cuts down on fatigue so you’re not constantly correcting and fighting the wheel.

Everything is built as a complete system and made to handle real trail use, with components designed to hold up under abuse. The kits are straightforward to install and matched to your axle and tie rod setup so everything works together right out of the box.
