Product Description
The PSC SK251 Cylinder Assist Steering Kit is a complete hydraulic steering upgrade designed for 2003-2006 Jeep Wrangler TJ and LJ models equipped with a Dana 60 axle. Built for serious off-road performance, this PSC steering system dramatically increases steering torque and control when running oversized tires, heavy axles, or aggressive locking differentials. Factory steering systems quickly become overwhelmed when vehicles are upgraded with 38-42 inch tires, aftermarket Dana 60 axles, and extreme off-road suspension setups. The PSC SK251 kit solves these issues by combining a high-performance steering gearbox, hydraulic assist cylinder, high-volume power steering pump, and pre-engineered hoses and brackets. This hydraulic assist system relieves stress from the steering box and frame mounts while delivering improved turning power and consistent steering feel on difficult terrain. The assist cylinder also functions as a dynamic steering stabilizer, improving steering precision and reducing driver fatigue on the trail. PSC steering systems are widely used in rock crawling, off-road racing, and heavy-duty Jeep builds where reliability and steering control are critical. Whether your Wrangler is a trail rig or an extreme crawler, the SK251 kit provides the steering performance needed to confidently handle the toughest obstacles.

Frequently Asked Questions
What does a cylinder assist steering system do?
A hydraulic assist steering system adds a steering cylinder that works with the steering gearbox to dramatically increase steering torque. This makes turning large tires and heavy off-road axles significantly easier while reducing stress on the steering box.
Why is hydraulic assist recommended for Dana 60 axle swaps?
Dana 60 axles combined with large tires place significant load on factory steering components. Hydraulic assist systems like the PSC SK251 provide the additional steering power required for reliable steering performance.
Is the PSC SK251 a complete steering system?
Yes. The kit includes a steering gearbox, hydraulic assist cylinder, pump system, hoses, fittings, and mounting hardware required for installation.
Will this system work with factory steering components?
This system is designed for Jeeps that have been upgraded with a Dana 60 axle and heavy-duty steering components. Additional modifications may be required depending on the specific axle and steering configuration.
What tire sizes benefit most from hydraulic assist steering?
Hydraulic assist steering is typically recommended for vehicles running 38-42 inch tires or larger where traditional steering systems struggle to provide adequate turning force.
