Experience the best of both worlds with the MRP Progressive Spring. Coil suspension has always been superior for small bump sensitivity, but always fell short not being progressive. The MRP Progressive Spring has solved this dilemma for their Hazzard rear shock. Experience a coil shock that is supple off the top and ramps up at the bottom. Finally run a coil shock on your favorite bike, even if it doesn't have a progressive suspension curve.
MRP Progressive Springs are the only non-linear shock springs on the market. They increase in rate late in stroke to provide additional bottom-out support and open up the use of coil shocks on frames previously only suited to air shocks.
As with our Enduro SL springs, these springs are offered in a single free length per rate that fits most shocks from 200mm (7.875") to 230mm.* They accomodate up to 65mm of shock stroke. A 1.5" / 38mm ID fits our Hazzard natively and spacer kits are available to use with other makes and models.
