Brembo 2H3.9003A2 GT Series Rear Big Brake Kit 380x32mm Red Calipers Type-3 Slotted

The Brembo GT Series 2H3.9003A2 is a complete rear axle big brake upgrade kit engineered for Chevrolet Silverado 1500 trucks. This high-performance braking system delivers motorsport-derived technology with dramatic improvements in stopping power, heat dissipation, and fade resistance for both street and track applications.

Complete Rear Axle Kit Includes:

• Two 4-piston aluminum calipers with red powder-coated finish
• Two 2-piece floating rotors measuring 380mm x 32mm (15 inches diameter)
• Type-3 slotted rotor design with optimized venting for superior cooling
• High-performance brake pad set with Brembo FM1000 friction material
• DOT/TÜV approved stainless steel braided brake lines
• CNC-machined billet caliper mounting brackets
• Complete mounting hardware and installation instructions

Advanced Engineering Features:

The cast aluminum 4-piston calipers provide rigid, consistent clamping force across the entire brake pad surface. The 2-piece floating rotor design separates the aluminum hat from the iron friction ring, reducing unsprung weight while maintaining thermal stability. Type-3 slotted rotors feature precision-machined slots that evacuate brake dust and gases while providing consistent pad bite throughout the temperature range.

Performance Benefits:

• Significantly increased rotor diameter and thermal mass over factory brakes
• Enhanced heat dissipation prevents brake fade during aggressive driving
• Improved pedal feel with reduced pedal effort and travel
• Pre-assembled for straightforward installation
• Two-year limited warranty against manufacturing defects

The Brembo GT System is designed for vehicles at original ride height and requires minimum 18-inch wheels for proper clearance. Professional installation recommended. This kit is intended for Silverado 1500 models with aluminum knuckles (2014-2018 GMT K2XX platform).
