Product Description
Upgrade your classic Jeep steering system with the PSC SK115 Cylinder Assist Steering Kit, engineered for 1980-1986 Jeep CJ5, CJ7, and CJ8 models with factory power steering. This premium PSC hydraulic assist system is built for rigs running 32-38 inch tires and is ideal for Jeeps that see serious trail use, larger tire loads, lockers, rocks, and harsh off-road steering conditions. PSC’s Cylinder Assist systems are designed to increase turning force by approximately 50 percent while maintaining road feel and reducing stress on the steering box, pump, and steering linkage. This makes the SK115 a high-value upgrade for CJ owners who want stronger low-speed steering performance, better control on obstacles, and more confidence with oversized tires.
The PSC SK115 kit is a proven steering solution for trail-driven and rock-crawling CJ platforms that need more assist than the stock system can deliver. It is specifically intended for 1980-1986 Jeep CJ5, CJ7, and CJ8 Scrambler applications with factory power steering, and it is best suited for builds running larger tires and increased front-end steering loads. Whether you are restoring control to a CJ with oversized tires or building a stronger steering package for aggressive off-road use, this PSC kit delivers the steering authority and durability serious Jeep owners look for.

FAQ
What does the PSC SK115 steering kit do for my Jeep CJ?
The SK115 adds hydraulic cylinder assist to help turn larger tires more easily, reduce stress on the steering gear, and improve steering control on difficult terrain.
What Jeep models does PSC SK115 fit?
This kit is designed for 1980-1986 Jeep CJ5, CJ7, and CJ8 models equipped with factory power steering.
What tire size is this kit designed for?
PSC markets this kit for builds running 32-38 inch tires, and supporting specs list a maximum tire diameter of 42 inches depending on the total vehicle setup.
Is this a good upgrade for trail and rock crawling use?
Yes. This kit is built for off-road conditions where larger tires, lockers, and obstacles place extra steering load on the factory system.
Does the PSC SK115 maintain normal steering feel?
PSC states its cylinder assist systems are designed to improve turning force while maintaining handling control and road feel rather than creating twitchy steering behavior.
Why should I upgrade from factory steering on a CJ?
Once larger tires and more traction are added, stock steering can struggle. A cylinder assist setup helps restore control, reduce steering effort, and improve durability under heavy use.
