MRP Progressive Springs are the only non-linear shock springs on the market. Progressive Springs 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.
- Effective rate - 350lb
- @ 25% Sag - 350lb
- @ 90% Travel - 375lb (51-60mm stroke) - 400lb (63mm+ stroke)
As with MRP's 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 a MRP Hazzard shock natively.
Spacer kits can be purchased separately to use with shocks of other brands.
