Kit Type

This kit is the clean, correct way to change power steering fluid and start fresh. It’s 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.

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.

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.
