Product Details

The 4302-48020 brake kit is engineered around OE-style fitment and braking consistency for rear axle service on GM trucks and SUVs. The DFC GEOSPEC rotor coating helps resist rust better than conventional paint or zinc finishes, while the machined rotor surface and balance inspection support smooth operation. The 3000 Ceramic pad compound is formulated for reliable friction, low dust, and fade resistance across a wide temperature range, making this kit a practical choice for daily driving and towing-focused use on Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD platforms.

Common Problems This Kit Can Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or poor pad-to-rotor contact
