Fitment & Compatibility

The supplied front applications distinguish 2019–2026 Silverado/Sierra 1500 trucks, the specifically listed 2022 LTD/Limited models, and 2021–2026 full-size SUVs. Escalade/ESV, Suburban, Tahoe and Yukon/XL retain their individual trims and year limits; Escalade-V starts in its separately listed years. Do not apply the truck start year to every SUV. Six-piston TX6R calipers use BP-22 pads and 16.00 × 1.38-inch Spec37 GT rotors with separate hats. Front hose kit 220-10979 is included. DS-1337 requires dust-shield trimming to the illustrated clearance profile, approximately 11.38 inches in diameter. Inspect aftermarket upright mounting lugs where applicable before assembly. Check the six-on-5.50-inch interface and wheel template; nominal minimum diameter is 20 inches.

Listed models: Silverado 1500; Sierra 1500; Escalade; Escalade ESV; Suburban; Tahoe; Yukon; Yukon XL; Silverado 1500 LTD; Sierra 1500 Limited. See the supplied table below for each year, submodel and equipment condition.
