PSC Motorsports Power Steering Flush

The Right Flush for High-Performance PSC Steering Systems

When you invest in a PSC Motorsports steering system — whether it's a Cylinder Assist® setup, a full hydraulic build, or a high-output pump upgrade — the fluid you run matters just as much as the hardware. That's why PSC Motorsports takes the power steering flush step seriously, offering a purpose-built solution designed specifically to work with their own components and fluids.

Why a Proper Power Steering Flush Matters

Power steering systems work hard, especially in high-heat, off-road, and heavy-use environments. Over time, fluid breaks down and carries debris that affects pump life, steering feel, and overall system performance. A proper flush clears that out before new fluid goes in.

Flushing the system with SWEPCO 729 Flushing Oil is the best way to remove all old lubricants and loose contaminants that might affect the service life or performance of SWEPCO Lubricants and PSC power steering components. This is especially critical because most synthetics are NOT compatible with SWEPCO Lubricants, making flushing highly recommended when switching from a full synthetic product to a SWEPCO Lubricant.

The FLK729 Premium Fluid Changeover Kit

PSC's FLK729 fluid changeover kit includes flush, PSC 715 fluid, and a reservoir filter for a clean, complete power steering service. This kit is the clean, correct way to change power steering fluid and start fresh — designed to flush out old fluid, suspended contaminants, and residue left behind by previous products so your PSC power steering fluid can do its job the way it's intended to.

The FLK729 bundles the right flush, the right fluid, and the right filter into one package, so you're not piecing things together or cutting corners. For anyone upgrading to PSC's own fluid or servicing an existing PSC system, this all-in-one kit eliminates the guesswork entirely.

PSC 715 Fluid and the Lubium® Advantage

The flush process leads directly into PSC's premium 715 power steering fluid. Blended from premium high VI paraffinic base stocks and enhanced with Lubium®, a proprietary additive developed by SWEPCO, PSC 715 delivers consistent performance under pressure and temperature extremes. The Lubium additive is a special anti-oxidation additive that prevents corrosion, oxidation, and wear, and also utilizes a unique friction modifier that has been shown to minimize power steering noise.

PSC's steering fluids are engineered for high-pressure systems, built to handle heat, and proven to keep pumps, steering gears, and Cylinder Assist® setups running smooth. The all-season formula features a broad temperature range for use in hot or extremely cold climates, preventing the fluid from gelling down to -40°F.

Built for Trucks, Jeeps, and Off-Road Builds

With an eye towards high-quality steering solutions for all brands of trucks and Jeeps, PSC brings a DIY attitude to each one of their pump kits, gearboxes, and steering kits. Their flush products reflect that same philosophy — straightforward, high-performance maintenance solutions that protect the hardware you've already invested in. Whether you're doing a full system rebuild or a routine fluid service, starting with a thorough flush using PSC's purpose-matched products ensures the best possible foundation for long-term steering performance.
