WP AER 35 Fork Kit designed and constructed by Lainer Suspension Racing - requires an Installation Pin Socket to fit

Designed to create a closed cartridge fork. You install a piston with valving shims which can be tuned to different settings based on the rider's weight and riding style - plus it gives increased sensitivity to the original adjusters (which don't work well from stock).

Supplied with the kit is a spring to increase comfort in the first part of the fork travel and a hydraulic bump stop to dampen the end of the stroke.

Included in the kit is an optional nitrogen valve to install in the fork leg.

The final result is a suspension similar to a WP AER 48 from KTM and Husqvarna 250's & 450's.

Please Note: Shims are not included in the kit - please see our 8mm Inner Diameter Shims and 12mm Inner Diameter Shims pages to buy in packs of 10.
