The kit’s custom drop-forged aluminum spring seats were made to cradle the coil in perfect position to soothe away any annoying squeaks and creaks. The coil springs are as happy as a chubby 4×4 baby in a muddy diaper. (Aren’t crawling babies technically 4×4 too?) The adjustable threaded body of the EDP-coated steel base bolts securely into place on top of the rear axle. Once secured, just spin the drop-forged aluminum spring seat down onto the adjustable threaded base and set it to your desired ride height. These allow for over 1 inch of adjustment. Also don’t forget, these Adjustable Airbag Delete Kits are great for eliminating the dreaded “Left Hand Lean” found on USDM vehicles. This is why having a solution to adjust your rear suspension is such a big deal. Until now, coil spacers could get you close, but now you can get it dialed in perfectly!
