The performance of your shock is directly related to the quality of your spring. Sprindex springs stand out amongst the competition by offering their proprietary on-the-fly adjustable design. With an inbuilt adjustable wedge which, when rotated, will alter your spring rate in 5lb increments, you can fine tune your ride for any terrain in seconds. Similar to other springs on the market, Sprindex springs have been optimised and constructed out of high quality steel. This allows for the same performance and durability you’d expect from a standard steel spring whilst using less material, and as a result, Sprindex have achieved a lighter weight final product.
