Key Features & Benefits
- 6-Piston Cast Monoblock Caliper — Rigid, single-piece construction eliminates flex under extreme braking loads, delivering consistent and progressive pedal feel even during repeated hard stops.
- 380x34mm Two-Piece Rotor Design — Larger rotor diameter dramatically increases thermal mass and leverage, reducing brake fade during sustained high-performance or off-road use where heat buildup is a constant challenge.
- TY-3 Slotted Rotor Profile — Brembo's proprietary TY-3 slot pattern continuously sweeps debris and gases away from the pad surface, maintaining maximum bite and extending pad life under aggressive driving conditions.
- Black High-Temp Caliper Coating — Durable black powder-coat finish resists corrosion, heat discoloration, and brake dust buildup while delivering an aggressive, race-inspired aesthetic through your wheels.
- Two-Piece Rotor Construction — An aluminum hat mated to a cast-iron friction ring reduces unsprung rotational weight compared to a full cast rotor, improving suspension response and steering precision.
- Direct OEM Fitment — Engineered specifically for the 2024+ Ford Ranger Raptor with no cutting, drilling, or custom fabrication required for a clean, factory-quality installation.
- Brembo Motorsport Pedigree — Brembo supplies braking systems to Formula 1, MotoGP, and WRC teams, bringing proven performance engineering directly to your street and trail truck.
- Improved Fade Resistance — Upgraded thermal capacity over the OEM system means consistent stopping distances lap after lap or descent after descent, even when towing or running at high speed off-road.

Fitment & Compatibility
This Brembo GT Big Brake Kit is engineered exclusively for the following applications:
- 2024+ Ford Ranger Raptor — Front Axle
Always verify wheel clearance before purchasing a big brake kit. A minimum wheel diameter of 20 inches is typically required to clear the 380mm rotor and 6-piston caliper assembly on the Ranger Raptor. Consult your wheel manufacturer or use Brembo's official fitment guide to confirm compatibility with your specific wheel setup. This kit is designed for vehicles retaining the OEM front suspension geometry.
Installation
The Brembo GT BBK for the 2024+ Ford Ranger Raptor is a direct-fit, bolt-on upgrade that uses the factory caliper mounting points — no cutting, welding, or fabrication is required. Installation requires basic hand tools, a brake line wrench, and a torque wrench. A professional brake system bleed is mandatory upon completion. Brembo recommends professional installation by a qualified automotive technician to ensure proper torque specifications, brake line routing, and system bleeding. Allow for a proper bed-in procedure following Brembo's guidelines to fully seat the pads to the new rotors and achieve optimal performance.
Is this kit CARB compliant? This is a performance brake kit intended for competition and off-highway use. Please verify local emissions and vehicle modification regulations before installation on street-driven vehicles in your region.
