Springs are compatible with MRP Raze and Hazzard shocks, as well as most other brands with the appropriate spring spacer kit (click here for more compatibility info). They feature a 1.5” ID and can accommodate shock strokes up to 65mm.

Enduro SL springs feature an advanced wind that reduces weight and length compared to traditional steel springs, giving you all the benefits of coil suspension without the weight penalty of standard steel springs or the expense of more exotic material options.

Progressive springs increase in spring rate late in their stroke to provide additional bottom-out support and open up the use of coil shocks on frames previously only suited to air shocks. Rate progression ranges from 20 to 27% depending on spring rate.
