ATP Valve Spring Compressor C‑Clamp Service Kit — 10‑Piece Black‑Oxide Set with 5 Collets & Molded Case

ATP Solid Valve Spring Compressor C-clamp Service Kit is a heavy-duty 10-piece tool set engineered to compress and release valve springs on most cars, motorcycles and small engines safely and efficiently.

This ATP kit pairs a robust C-type jaw and ergonomic hand lever with five collet adapters and extension screws stored in a molded carry case. Built from heat-treated steel with a black-oxide finish, each component resists corrosion and is dimensioned to handle the stresses of spring compression so you can remove and install valves without improvised fixtures.

How does this kit make valve spring removal easier?

The kit centralizes everything needed to compress valve springs into one compact, portable package so you avoid jury-rigging or multiple trips to the bench. The C-clamp jaw aligns straight to reduce slipping while the range of collet sizes adapts to different valve retainer geometries.

• Includes five push adapters (16, 19, 23, 25, 30 mm) to fit varied retainers.
• 1.7 mm heat-treated steel parts resist bending under load.
• Max jaw opening 9-1/2" covers many cylinder head thicknesses.
• Molded case keeps tools organized and protected during transport.

What parts are included and what are their roles?

The set contains the components you need to compress valve springs and support different service scenarios. Collets engage retainers, extension screws alter reach for deep seats, the C-type jaw provides firm clamping, and the 4" hand lever applies controlled force.

• Five push adapters for engaging various retainer sizes.
• Three extension screws (two 4.4" and one 3") for reach adjustment.
• One solid C-type jaw with aligned ends to reduce slippage.
• One 4" hand lever for manual compression control.

Will this kit work on my vehicle or engine type?

The ATP compressor is designed for broad compatibility with most light automotive and small-engine applications. It fits many cars, motorcycles, ATVs, UTVs and small vans, but verify retainer diameter and head clearance before use to ensure fit and safe operation.

• Adapters cover common retainer sizes from 16 mm to 30 mm.
• Maximum jaw opening of 9-1/2" suits thicker heads and assemblies.
• Extension screws increase reach for recessed valves.
• Intended for professional and home mechanic use; check specific engine specs.

Who is this for? ATP's Solid Valve Spring Compressor C-Clamp Service Kit is built for mechanics and DIYers who perform valve jobs on light vehicles or small engines and want a durable, all-in-one solution. If you routinely remove retainers across multiple engine types or need a portable set for fieldwork, this tool set streamlines the job while protecting parts and reducing the need for makeshift tools. Always follow engine manufacturer guidance and proper safety procedures when compressing valve springs.
