Wholesale only · Full payment before shipment · Send your machine nameplate to confirm fitment
Description
Compression springs are typically made of high-strength steel wire that can withstand the high temperatures and pressures generated within the engine. The compression spring must be properly sized and calibrated, which is important to ensure efficient and reliable engine operation. A compression spring is a spring of helical design that gains compression and tension through spring compression (shortening) as more load is applied.
Features
