Supertech BMW S42/M42/M50/S50/M52/M54 Dual Valve Spring Kit
Supertech valve spring kit for BMW M54 applications are designed for racing reliability and high-RPM use. Key specs: Spring type: Dual Valve Spring, Seat pressure: 80lbs @ 35.70mm, Open pressure: 195lbs @ 10.00mm, Spring rate: 11.50lbs/mm, Max lift: 12.70mm, and Safe RPM: 8000. Each kit is matched as a complete valvetrain package — springs, retainers, locators and locks — so installation is straightforward and clearance issues are eliminated. Built to control valve motion at high RPM, reduce valve float and support aggressive cam profiles. Compatible with most aftermarket and OEM camshafts within the rated lift range. Installation requires verifying installed spring height with the included shims and confirming retainer-to-seal clearance. Recommended for any build running aggressive cams, increased RPM ceilings, or forced induction. Backed by Supertech's reputation for valve spring engineering and racing reliability.
