HRATF75PR148 - Progressive Rate Front Spring Set 1:10 Arrma 4X4 3S

Set of progressive rate springs designed to replace the stock suspension springs on Arrma 1/10 3S RC vehicles. The progressive coil‑rate design provides softer initial travel for small bumps and increasing stiffness toward the end of travel for improved bottom‑out resistance and handling stability. These springs help balance ride compliance with control during aggressive driving and jumping.

• progressive rate coil design delivers smooth initial compression and firmer end‑stroke support

• optimized spring lengths and rates suit Arrma 3S scale shock absorbers

• improves traction and bump absorption with reduced harsh bottom‑out feel

• compatible with front or rear suspension setups on Arrma 1/10 3S vehicles

• high‑quality spring steel resists fatigue and deformation under repeated use

• consistent manufacturing tolerances help maintain balanced suspension performance

• set includes four springs for complete shock replacement
