Now available for long-bed iterations of the 2011-2012 Ford F-450, the R4Tech kit is a hybrid air/leaf suspension setup that replaces the factory leaf springs. Claimed benefits include an improved ride by adjusting to the conditions using the variable spring rate of the air spring to stiffen when the truck is loaded and soften when it’s unloaded. It also improves headlight aim and driveline angles. The complete kit includes leaf plates, lower trailing link, J-spring, spring perches and mounting brackets, as well as the air springs and onboard compressor.

MSRP: $2,298
