PSC High Pressure Hose Kit 03-07 Ram 5.9L Cummins With Hydro-Boost
Description
Restore dependable steering and brake-assist performance with the PSC Steering High-Pressure Hose Kit for 2003–2007 Ram 2500/3500 4WD trucks equipped with the 5.9L Cummins and Hydro-Boost braking system. Designed to replace aging, worn, or leaking hydraulic lines, this kit helps maintain reliable fluid delivery between the power steering pump, Hydro-Boost unit, and steering gear. It’s a practical upgrade for trucks that tow, haul, and work hard, where consistent steering response and brake assist are essential.
Each hose assembly is cut to the correct length and crimped to PSC specifications for a vehicle-specific fit and clean, factory-style routing. The high-pressure lines are engineered to handle the demands of a hydraulic steering and Hydro-Boost system, while precision-crimped fittings provide secure connections when properly installed. Built for dependable service, these assemblies help eliminate the fitment challenges and uncertainty that can come with adapting universal hoses to your truck.

How it works
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
Pricing
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
Your privacy
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.
