69-3030 - 3""F/2""R SST Lift Kit - GM Silverado/Sierra 2500/3500 HD For those who want a more lifted stance all the way around, we now offer the 69-3030 3""/2"" SST Lift Kit. This system provides 3"" of adjustable front lift with new forged torsion keys specialized for this 3"" front lift (not the same keys found in 66-3020). Taller differential drop spacers and skid plate spacers are included, as well as new taller bump stops, rear shock extensions and our popular OE style cast iron 2"" tall rear lift blocks with new longer U-bolts. Like the 66-3020 leveling kit, the 69-3030 SST lift kit works with trucks equipped with either the OE #84461807 or OE #84634344 factory torsion keys and requires ReadyLIFT torsion key unloading tool 66-7816A or similar for installation. We thank our customers for being patient while we have developed two very specific products for a very unique all-new truck. With thousands of miles logged testing each of these kits, we are confident that you will enjoy what our 2020-2021 GM HD leveling and SST lift kits offers in terms of performance and ride quality.
