IMPORTANT NOTE: Due to premature upper control arm ball joint wear on 2019+ GM 1500 trucks (including AT4 & TrailBoss), BDS Suspension highly recommends 121253 upper control arms to be purchased with this lift system. BDS Suspension adds to its lineup of heavy duty upper control arms (UCA) with new kits available for the new 2019-2020 Chevy Silverado and GMC Sierra 1500 trucks. These new UCAs are designed for improved strength, great looks, and increased suspension droop travel. They are built from high strength 1.5" OD x .120-wall tubing, fully welded for strength and durability. They use an indexed ball joint cup to correct the ball joint positioning to be used with most levelign and full lift kits on the market. The frame mounting ends feature durometer-specific rubber bushings for long lasting durability and reduced NVHs. At the other end they utilize premium quality greaseable ball joints for smooth, quiet operation and superior corrosion resistance to arms that feature uniballs, poly bushings or heims. These control arms come finished in a durable semi-gloss black powder coat and include a billet aluminum machined ball joint dust cap that can be removed to easily service the greaseable ball joints. They integrate a mounting tab for the factory ABS lines so there's no need to zip tie the lines as is the case with other kits on the market. The control arms come fully assembled for easy install right out of the box compatible with most leveling and lift kits on the market to increase wheel travel. In addition to the arms, optional weld-on steering stops are supplied for trucks using factory wheels as well as a wheel spacer for clearance in the event the factory spare tire needs to be installed. Get more from your new late model GM truck with this Performance UCA Kit from BDS Suspension.
