FPS Tappet plate reinforced spring for V2/V3 gearboxes

The FPS MARSV2/V3 Reinforced Tappet Plate Spring is a high‑quality, Italian‑engineered upgrade designed to deliver reliable feeding and eliminate the dreaded “mid‑cap syndrome” in V2 and V3 AEG gearboxes. Built in collaboration with leading industry partners, this spring is manufactured from burnished, pre‑hardened carbon steel wire enriched with silicon and chromium (EN10270/2) — a material blend chosen for its exceptional elasticity, fatigue resistance and long‑term stability.

Immediately after forming, each spring undergoes a 400 °C thermal stabilization process for 30 minutes, dramatically increasing durability and ensuring consistent tension even under rapid‑fire or high‑stress conditions. Whether you’re refreshing a worn tappet system or completing a full gearbox rebuild, this is a simple, effective and long‑lasting upgrade.

Key Features:

• Reinforced tappet plate spring for V2/V3 gearboxes
• Designed to resist pressure from fully loaded mid‑caps
• Eliminates or drastically reduces feeding issues
• Made from EN10270/2 silicon‑chromium carbon steel wire
• Heat‑treated at 400 °C for maximum lifespan
