Product Description
The PSC SK688R38JP1-6.75W-1.5 Cylinder Assist Steering Kit is a complete hydraulic steering upgrade engineered for 2007-2011 Jeep Wrangler JK models equipped with the 3.8L engine. Designed for vehicles running oversized tires, upgraded axles, or heavy off-road use, this PSC steering kit dramatically reduces steering effort while improving steering control in extreme terrain. This kit features a weld-on 6.75 AFM axle mount and is designed for 1.5-inch tie rods, making it ideal for high-strength aftermarket steering systems commonly found on rock crawlers and heavily modified trail rigs. The PSC hydraulic assist cylinder works with a heavy-duty steering gearbox to provide additional steering force, reducing stress on the steering box and steering linkage. PSC steering systems are widely trusted in the off-road industry because they deliver the strength and reliability needed for aggressive trail use. Whether you're building a Jeep for rock crawling, trail riding, or heavy-duty off-road performance, the PSC SK688R38JP1 steering kit provides the power and durability required to maintain precise steering control.

Frequently Asked Questions
What does a hydraulic cylinder assist steering kit do?
A hydraulic assist steering system adds a hydraulic ram to the steering linkage to help turn oversized tires. This reduces steering effort and protects the steering gearbox from excessive load.
Is welding required for this kit?
Yes. This version of the PSC steering kit uses a weld-on 6.75 AFM axle mount that must be welded to the axle housing for proper installation.
Will this work with stock tie rods?
No. This kit is designed for vehicles running aftermarket heavy-duty steering with a 1.5 inch tie rod.
Why upgrade to PSC hydraulic assist steering?
PSC steering systems dramatically improve steering control when running large tires, beadlock wheels, lockers, or high-traction off-road terrain. They are widely used in professional rock crawling and competition off-road vehicles.
Is this kit designed specifically for the Jeep JK platform?
Yes. This PSC kit is engineered specifically for the 2007-2011 Jeep Wrangler JK with the 3.8L engine and is designed to integrate with common JK steering upgrades.
