Product Description
Upgrade the steering performance of your Super Duty with the PSC SG755R Cylinder Assist Steering Gearbox. Engineered by PSC Steering Components, this heavy-duty Big Bore XD steering gearbox is designed specifically for trucks running larger tires, lifted suspension systems, or off-road steering loads that overwhelm factory steering boxes. The SG755R is pre-ported for hydraulic cylinder assist, making it the ideal upgrade for serious off-road builds, rock crawlers, and heavy-duty work trucks. Unlike remanufactured units, the PSC SG755R steering gearbox is built using 100% new components and a reinforced gear housing designed to withstand extreme steering loads. Integrated -6AN assist ports allow simple connection to PSC hydraulic assist systems while maintaining compatibility with factory steering setups if capped. The optimized internal bore increases steering torque output, improving steering response and control when running oversized tires, locking differentials, or heavy front-end accessories.
