Bolt on a set of ICON Vehicle Dynamics rear hydraulic air bumpstops to improve the on or off-road capabilities of your 2005-UP Toyota Tacoma when using maximum suspension travel. ICON’s race proven hydraulic air bumpstops are tested, tried and true, from Cabo to Canada in all conditions. This vehicle specific tuned hydraulic air bumpstop system offers both smooth engagement, maximum bottom resistance, and smooth controlled return while being used in extreme conditions. The true value to using a compression and rebound tuned bumpstop is the exponentially increasing force is smooth, not abrupt or harsh like the OEM bumpstop.; As part of the kit, ICON includes an industry first selectable install height for the hydraulic air bumpstop so up travel is not limited with use of an aftermarket thicker leaf pack. This allows you to upgrade your leaf springs down the road, and retain maximum up travel without having to purchase a new bump stop bracket kit.
