ReadyLIFT offers a premium-grade performance coil over shock upgrade kit exclusively designed for 2007-2021 Toyota Tundra trucks equipped with our 6" and 8" big lift kits. This innovative 46-5780 Bilstein coil-over shock kit based on Bilstein's renowned 8125 series reservoir coil-over shock technology was developed in collaboration with Bilstein's shock research team to provide optimal performance for Tundra big lift kits especially those fitted with large off-road tires. The 46-5780 kit is tailored for 2WD/4WD Tundras (excluding TRD Pro models) and has been highly anticipated. It incorporates Bilstein's 2.625" monotube design reservoir coil-overs meticulously tuned through over a year of testing by ReadyLIFT and Bilstein engineers for custom valving. The lower rod ends feature 3/4" bearings and proprietary high misalignment spacers while ReadyLIFT-specific 90-degree reservoir fittings ensure ideal canister placement and hose fitment. Collaborating with Eibach ReadyLIFT introduced a unique ERO coil spring specifically crafted for this application distinguished by its silver powder coat finish with the ReadyLIFT brand name. The compatibility with our 6" and 8" lift kits is achieved through our heavy-duty plate steel upper shock mount engineered to seamlessly integrate this performance coil over with the market's most popular Tundra lift kit. The combination of these top-notch lift kits and performance reservoir coil over shocks coupled with premium coil over springs results in an exceptional product. Made in the USA these performance coil-overs offer unmatched ride quality with the added advantage of rebuildability if necessary. Plus they enhance the aesthetic appeal of your Tundra once installed. Experience the ultimate in Tundra suspension with ReadyLIFT's 46-5780 upgrade kit.
