Frequently Asked Questions
What does a hydraulic cylinder assist steering kit do?
Hydraulic cylinder assist steering systems use a steering cylinder connected to the steering linkage to help the steering gearbox turn the wheels. This greatly reduces steering effort and improves control when running oversized tires or heavy off-road setups.
Is this kit designed specifically for Jeep JK models?
Yes. The PSC SK688R38JP1-8.0W-1.5 kit is designed for 2007-2011 Jeep Wrangler JK vehicles equipped with the 3.8L engine and compatible steering components.
Why do off-road vehicles need hydraulic steering assist?
When vehicles run large tires and heavy suspension modifications, the factory steering system struggles to provide enough torque. Hydraulic assist steering systems add extra steering force to improve durability and steering performance.
Does this kit require welding?
Yes. This version of the kit uses a weld-on axle mount designed for 8.0 AFM axle setups, allowing a strong and secure mounting location for the hydraulic steering cylinder.
Is PSC steering equipment used in competition off-road vehicles?
Yes. PSC Motorsports steering components are widely used in professional rock crawling, desert racing, and extreme off-road builds due to their reliability and steering performance.
