Return spring designed for consistent push-rod tension and fast recovery in V2/V3 gearboxes. Manufactured from pre-hardened, blackened carbon steel (EN10270-2) with thermal stabilization to resist relaxation and fatigue, the MASV2/V3 spring improves reliability under heavy-use scenarios including mid-cap feeding. Ideal for routine maintenance and performance rebuilds.

Warnings & usage information (GPSR compliant)

Do not tamper with or alter the spring: modification can change spring rate and compromise safety.

Ensure replica is unloaded and springs are de-tensioned before installation; follow correct gearbox disassembly procedures or use a qualified technician.

Use appropriate tools and check the hook engagement on the push-rod after fitting.

Perform low-power static and dynamic checks after installation to verify timing.

Store dry, avoid chemical exposure and dispose of packaging according to local rules.
