Product Description If you own a BoXXer Race, Team, RC, R2C2 or World Cup from model year 2010 (35 mm chassis), you can upgrade your fork with the Charger Damper™ Upgrade Kit. The Charger™ provides consistent damping, reduces vibration and is nearly 100 grams lighter than the traditional BoXXer shock. The kit includes the complete right inner workings, as well as the breather kit including oil.

Improved bladder material The extruded bladder material is incredibly durable, withstands damping changes on long descents and has virtually no offset for perfect response to small shocks.Manufacturer Number:00.4018.783000 Contents:1 x RockShox Charger upgrade kitincl. bleed kit Manufacturer: SRAM LLC 1000 W.
