Progressive Suspension 31-4011 Monotube Cartridge Fork Kit

Asymmetrical design places a preload adjuster over a progressive rate spring in one leg and an aluminum-bodied, sealed cartridge damper on the other; providing superior damping and ride control combined with tunable preload and a new benchmark for high performance suspension. Improves resistance to front brake dive, front end stability, cornering and bottoming control. Adjustable to standard length or to lower the front end up to 1in. Complete fork internal replacement kit. No modification for forks required. Made in the U.S.A..
