Description
Product Overview
The ATPEAM Valve Spring Compressor is engineered for mechanics and DIY enthusiasts who demand precision and durability when working on engine valve trains. Crafted from high‑strength steel and finished with a rust‑resistant black oxide coating, the tool maintains its integrity under the high tension of compressed springs. The kit includes five interchangeable valve spring adapters to accommodate a wide range of bore sizes, a heavy‑duty C‑clamp for secure compression, extension bolts for added reach, a solid compression bar, and lapping tools for fine adjustments. All components are housed in a rugged, compartmentalized case that protects the tools and simplifies transport.
Usage
Designed for versatility, this compressor excels on motorcycles, ATVs, UTVs, passenger cars and small engines such as lawn‑mower or generator units. Whether you are performing routine maintenance, rebuilding a valve train, or conducting a complete engine overhaul, the tool provides consistent pressure and easy access in tight engine bays. Its ergonomic design reduces hand fatigue, allowing prolonged use in professional shops or home garages.

FAQ
What types of engines can this compressor be used on?
The tool is suitable for motorcycles, ATVs, UTVs, passenger cars and small engines such as lawn‑mowers, generators and go‑karts.
How do I select the correct adapter size?
Measure the diameter of the valve spring you are working with and choose the adapter that matches that size; the kit includes a range of common sizes to cover most applications.
Is the black oxide coating enough to prevent rust?
Yes, the black oxide finish provides excellent corrosion resistance for typical workshop conditions, but we still recommend storing the tool in a dry environment.
Can the compressor be used for repeated spring removal without loss of accuracy?
Absolutely. The heat‑treated steel components retain their dimensional stability, ensuring consistent performance even after many cycles.
What is included in the storage case?
The case holds all five adapters, the C‑clamp, extension bolts, compression bar, lapping tools and a user manual, each in dedicated slots for easy organization.
