ValveMaster ProClamp™

Make valve service safer, faster, and more precise with the ValveMaster ProClamp™ Valve Spring Compressor Kit, a complete professional-grade solution for removing and installing valve springs on automotive engines, small engines, motorcycles, ATVs, and more. Designed for mechanics and engine builders, this all-in-one kit provides every tool needed for accurate, damage-free valve work.

Built with a heavy-duty forged steel C-clamp, the ProClamp™ delivers exceptional strength and rigidity, ensuring it won’t bend, flex, or twist under high compression loads. The oxide-finished steel construction provides long-lasting rust and corrosion resistance, maintaining smooth operation in tough workshop conditions.

The kit includes 5 precision collet sizes, extension screws, and pushers to ensure proper fitment on a wide range of valves and cylinder heads. Whether you're working on compact small-engine valves or larger automotive cylinder heads, the ValveMaster ProClamp™ provides perfect alignment and stable compression for safe and efficient removal or installation.

Using the compressor is straightforward and secure:

1. Position the tool and close the C-clamp until it contacts the spring’s center rod.

2. Insert the compression fork into the coil spring.

3. Carefully compress the spring to remove or install retainers.

4. Release tension only when the spring is properly seated.
   Always follow safe handling techniques.

For portability and organization, the entire set is housed in a rugged, custom-molded storage case that keeps each component secure, accessible, and protected for years of reliable use.

Durable, precise, and workshop-ready, the ValveMaster ProClamp™ is the essential valve spring compressor kit for anyone performing head repairs, valve maintenance, and engine rebuilds.
