Description
The included ICON billet aluminum upper control arm kit is designed to improve overall performance with corrected front-end geometry, increased on-vehicle camber and caster adjustment, improved suspension component clearance, and when paired with the extended travel front shocks, increases wheel travel over the OEM configuration to maximize suspension performance. Additionally, replacing the OE ball joint with the serviceable and rebuildable ICON Delta Joint Pro HD allows for full bump and droop travel of the front suspension while eliminating bind. The included torsion keys install onto the factory torsion bars and allow for 2-3.5” of front lift height adjustment to allow for a level stance and larger, more aggressive wheel and tire fitment. ICON rear leaf packs provide improved ride quality while maintaining factory rear ride height. These full replacement leaf back lowers the rear spring rate approximately 20% compared to stock as well as shifts the overload transition point higher in the suspension travel to improve small bump compliance. While driving the construction site or trails to your favorite dirt bike location, ICON wants you to get there in comfort, just like your drive to work.
