Product details:

Featuring a Super Light Steel (SLS) construction, this mountain bike (MTB) rear shock spring is lighter than titanium springs and more affordable. It's equipped with a proprietary surface treatment and stress relief process that removes residual stresses from the spring, allowing it to withstand higher stresses. Each spring is also optimised by using a smaller wire diameter and fewer coils, creating a lighter spring. Compatible with Fox DHX2 and Van RC rear shocks from 2016 onwards.Internal Diameter: 35 mm/1.385"
