In fall of 2018 we announced our new leveling and SST lift kit offerings for the all-new GM 1500 trucks. We specifically did not include the factory lift kit-equipped GMC AT4 and Chevy Silverado Trail Boss. The AT4/Trail Boss are factory equipped with a 2" front lift. This front lift includes a longer front shock/strut assembly. When combining a traditional leveling kit on these factory lifted trucks, several issues present themselves including binding problems with the factory control arm ball joint and contact concerns with the lower strut/CV axle assembly. The ReadyLIFT 66-3921 1.75" leveling kit is similar to our popular 66-3086 leveling kit for pre-2019 trucks. The 66-3921 leveling kit provides required amount of lift without causing conflict with the factory strut geometry and clearances. In light of the factory upper control arm's lack of dynamic range when the AT4/Trail Boss truck is further lifted, this leveling kit includes our popular tubular upper control arms with corrected ball joint cup angles, heavy-duty replaceable ball joints and out new Terrain Control Technology (TCT) maintenance-free pivot bushings with side-biter washers to improve alignment retention. Includes DOM tube steel upper control arms with TCT maintenance-free pivot bushings and 1-ton ball joints CNC machined aircraft-grade billet aluminum top and bottom strut spacersKIT COMPONENTS Heavy Duty tubular steel upper control arms with TCT maintenance free pivot bushings and heavy-duty 1-ton ball joints.CNC machined billet aluminum top and bottom mount strut spacers.ABOUT THE MANUFACTURERReadyLIFT® Suspension Inc. was founded in 2006 on the principals of developing a line of economical yet innovative suspension leveling products that would allow Truck and SUV owners to be able to “level” their vehicle in order to install Plus-size wheels and tires. ReadyLIFT realized that there was a huge consumer market that didn’t want a big lift kit that would compromise fuel economy along with the factory ride and handling. The original ReadyLIFT line of suspension products was developed to provide consumers with a cost-effective alternative for their needs, essentially designing the exact product they were looking for – clearance for bigger wheels and tires, an improved ‘leveled’ stance, and that “factory” ride & handling.ReadyLIFT Suspension Inc. was acquired by Mangrove Equity Partners in 2015. This ownership group is committed to growing ReadyLIFT and its subsidiaries into strong, capable aftermarket equipment brands. To that end ReadyLIFT acquired All Sales Manufacturing in 2016 to bolster its manufacturing and machining capability. The acquisition also yielded a wonderful brand ready to blossom – AMI Styling. AMI Styling is a leader in billet accessories with products including emblems, door handles, fuel doors, antennas, knobs, grab handles, levers, and recovery products including Demon Hooks.ReadyLIFT is the most widely known and consequently the most successful manufacturer of leveling, mild and complete ‘big’ lift kit systems in the market today. By providing quality products designed and manufactured to give the customer exactly what they want without compromising ride or handling quality, the message has been well received.Ask us about saving money with our PACKAGE DEALSCP Cometic ACL Ferrea and ARP KitsCustom Made Package DealsAEM Package DealsPackage DealsAsk us about combining purchases for package deal auctionsPistonsRodsBearingsHead and Main Studsand more...ShippingWe ship via UPS/USPS/FEDEX/ONTRAC ground depending on the address of buyer unless instructed to do differently.We also offer expedited shipping at an extra cost.International shipping rate applies to addresses in all other locationsCustom/duty/brokerage fees, if any, on Canada and international orders are the responsibility of the buyer.Item ships within one business day after the payment has cleared or same day if paid by 12pm PST unless additional handling stated.
