HRSLF63FS261 - Progressive Rate Fs Rear Spring Set TRA Slash/Stampede 4x4

This product is a pair of progressive rate rear springs designed to improve suspension performance on 1/10 scale RC vehicles. The progressive coil design provides a softer initial rate for small bumps and increased stiffness as compression deepens, enhancing both traction and bottom-out resistance. Made from high-quality spring steel, they offer consistent performance and durability under aggressive driving. These springs help balance handling and support weight transfer in off-road and racing conditions. The specified 63 mm free length and tailored spring characteristics ensure predictable response throughout the suspension travel.
