Product Description
The PSC SK688R38JP1-6.75W-1.375 Cylinder Assist Steering Kit is a complete hydraulic steering assist solution designed specifically for 2007-2011 Jeep Wrangler JK models equipped with the 3.8L engine. This PSC steering kit dramatically improves steering control when running oversized tires, heavy off-road suspension setups, and extreme rock crawling environments. This configuration features a weld-on cylinder mount designed for 6.75 AFM axle housings paired with a 1.375" diameter tie rod system. The hydraulic assist cylinder reduces steering effort by allowing hydraulic pressure to share the load of turning large tires, preventing steering box stress and improving driver control during low-speed technical terrain. PSC hydraulic assist steering kits are widely used by off-road racers, trail rigs, and rock crawlers due to their ability to handle extreme steering loads while maintaining smooth steering response. By combining PSC's precision-built assist cylinder, mounting brackets, and steering components, this system delivers maximum reliability and performance for demanding Jeep builds.
