FPS Tappet plate spring for V2/V3 gearboxes

Description

The FPS MASV2/V3 Tappet Plate Spring is a high‑quality replacement spring designed for Version 2 and Version 3 AEG gearboxes, offering reliable feeding performance and long‑term durability. Manufactured in collaboration with leading industry partners, this spring is made from burnished, pre‑hardened carbon steel wire enriched with silicon and chromium (EN10270/2) — a material choice that ensures excellent elasticity, fatigue resistance and stability under rapid cycling.

Immediately after forming, each spring undergoes a 400 °C thermal stabilization process for 30 minutes, significantly increasing its lifespan and maintaining consistent tension even in demanding builds. Whether you’re refreshing a worn tappet system or completing a full gearbox rebuild, this is a dependable, Italian‑made upgrade that restores smooth, reliable nozzle movement.
