This full hydraulic steering kit is built for Jeep Wrangler TJ's running the 4.0L engine and pushing over‑40" tires. Designed to work with the factory pump bracket, it delivers the steering control and reliability needed for locked axles, heavy tires, and hard trail use.

The system is engineered as a complete package, using matched components that work together to eliminate weak points found in modified factory steering. It’s a proven setup for TJs that have outgrown traditional steering systems.
