Product description

The shock absorber springs are part of the SUSPENSION GROUP-REAR and serve as a replacement or upgrade component for the rear suspension. The progressive spring rate achieves a variable spring hardness, which feels soft under low load and gradually increases under higher load. This improves driving stability and comfort, especially in changing road conditions or different payload weights.

The springs have a robust chrome finish that protects against corrosion and supports a long service life. The 238mm length is designed for the rear mounting position and meets the requirements of the 12-Series shock absorbers. The product is supplied as a pair to ensure equal spring action on both sides of the rear wheel.

These shock absorber springs are suitable for heavy-duty applications and are intended for users who value reliable and resilient suspension. The simple progressive spring rate enables comfortable basic suspension with additional reserves under increased load.
