HRATF90PR148 - Progressive Rate Rear Spring Set 1:10 Arrma 4X4 3S

This product is a set of rear progressive‑rate suspension springs engineered for 1/10 scale Arrma vehicles to improve handling and ride quality. The progressive wind‑up design means the spring rate increases as it compresses, offering softer initial suspension action for small bumps and firmer resistance for heavy landings or aggressive driving. Made from high‑quality spring steel with a protective finish, these springs resist fatigue and corrosion. They enhance rear traction and stability while helping reduce bottom‑out on rough terrain.
