The Wilwood TX6R rear big brake kit pairs radial-mount six-piston calipers with 15.50 in GT-60 Spec-37 alloy rotors to deliver consistent stopping power and high-heat durability for heavy-duty applications. Kits replace factory discs while retaining the OE parking brake assembly and include radial mount brackets and installation hardware. For 2011–2015 GM 2500 trucks and SUVs; braided stainless flex lines may be needed separately.
