DBA 42074S 4000 Series T3 Rear Slotted Brake Rotor for 2015-2017 Chevrolet SS

Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling. DBA's metallurgy is able to handle the increased stress and heat generated under intense braking application time and time again. Featuring DBA;s patented Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars. DBA achieves up to a 30% increase in surface are and 20% improvement in cooling efficiency compared to traditional straight vane design. 4000 SERIES T3 is the ultimate in direct replacement single piece performance brake rotors Featuring all the benefits of the 4000 Series plus DBA?s patented world renowned T3 bi directional slot design. Built on the foundations of DBA's T2 slot, the T3 slot design features additional, precise, CNC machined tri-symmetrical slots, resulting in an even quieter, more responsive and smoother brake pedal feel The T3 slot increases the number of exit points for brake pad friction dust and gases to escape through, further increasing the consistency and effectiveness of every brake stop, DBA's revolutionary universal slot design eliminates the need for separate left and right slot designs seen in traditional rotor designs, DBA's 4000 Series T3 rotors are recommended for all performance applications from street driving, 4?4 and SUV, light utility vehicles, track days, rally cars and armored vehicles, DBA's 4000 Series rotors feature: XG-150 High Carbon Alloyed Iron, TSP (Thermal Stability Profiling), Thermo-graphic paint markings (THGP), Direct replacement suitability, Moisture proof corrosion protection packaging

The DBA 42074S 4000 Series T3 rear slotted brake rotor is a direct-replacement performance upgrade for select 2015-2017 Chevrolet SS applications. Designed for demanding street driving, performance use, and track-day conditions, this single-piece rotor combines high-carbon alloyed iron with advanced thermal management to deliver consistent braking performance under repeated heat and stress.

Cast from DBA XG-150 high-carbon alloyed iron and processed with Thermal Stability Profiling (TSP), the 42074S is engineered to resist heat-related distortion and maintain dependable pedal feel during intense braking. DBA’s patented Kangaroo Paw ventilation uses 144 diamond- and teardrop-patterned pillars to increase surface area and improve cooling efficiency compared with conventional straight-vane rotor designs. Thermo-graphic paint markings provide a visual reference for monitoring operating temperatures.

The 4000 Series T3 rotor also features DBA’s patented bi-directional tri-symmetrical slot design. Developed from the T2 slot platform, the CNC-machined T3 slots provide additional exit points for brake dust and gases while promoting smooth, responsive pad engagement. The universal slot design eliminates the need for separate left- and right-hand rotor versions, simplifying installation while supporting consistent braking performance. Moisture-resistant corrosion-protection packaging helps preserve the rotor before installation.

Fitment: 2015 Chevrolet SS, 2016 Chevrolet SS, and 2017 Chevrolet SS. Confirm vehicle configuration and axle position before ordering.
