Product Description
The PSC SK688R38JP1-6.75W-1.625 Cylinder Assist Steering Kit is engineered for serious off-road Jeep builds running oversized tires and high-stress trail conditions. Designed specifically for the 2007-2011 Jeep Wrangler JK with the 3.8L engine, this PSC hydraulic assist system dramatically reduces steering effort while improving steering control and durability in extreme terrain. This complete PSC steering solution uses a weld-on hydraulic assist bracket designed for a 6.75" AFM axle configuration and a 1.625" diameter tie rod, making it ideal for aftermarket heavy-duty steering systems commonly found on lifted JK builds. The PSC hydraulic assist cylinder works in conjunction with a PSC steering gearbox to provide additional steering force, allowing drivers to maintain precise steering control even with large tires, beadlock wheels, and locked differentials. PSC Motorsports steering systems are widely used in competitive rock crawling, desert racing, and extreme trail builds thanks to their high-strength components, precision engineering, and proven reliability. This kit provides the performance needed to confidently steer vehicles equipped with aggressive suspension setups and oversized off-road tires.
