This is the ultimate steering upgrade for your 7.3L Super Duty. PSC’s BIG BORE XD Cylinder Assist Kit replaces every weak link in the factory system with heavy-duty components built to handle oversized tires, towing, and tough trails.

A high-performance pump, remote reservoir, fluid cooler, SR-VT Anti-Splash Valve, and PSC Cylinder Assist system all work together to deliver serious steering muscle without the hassle of custom fabrication.

Everything you need is in the box—hoses, hardware, brackets—engineered for a clean, bolt-on install. Just add PSC 715 fluid and enjoy steering that feels right again.
