The TTSPORT OR6 front big brake kit is built for loaded Ford Bronco and Bronco Raptor (U725) builds running larger tires, armor, winch, roof tent, and recovery gear. It targets predictable pedal control on long descents, washboard roads, and slow technical sections — not headline bite numbers.
Stock front brakes were sized for stock weight and stock tire diameter. Add 35s, a steel front bumper, a winch, sliders, and a rooftop tent, and the front axle is doing more work every time you slow down. Heat builds faster, pad bite changes through a descent, and the pedal starts to feel different from corner one to corner ten.
OR6 increases front clamping capacity and thermal headroom so the pedal stays consistent when the truck is loaded and the grade is long.
Forged 6-piston front calipers with 79 cm² total piston area per caliper for managing added curb weight.
2021-2026 Ford Bronco and 2022-2026 Ford Bronco Raptor (U725) use the OR6 Ø340 mm × 32 mm front rotor specification.
Heat-treated high-carbon iron rotors, internally vented, sized for sustained heat on long downhills.
One-piece heat-insulated pistons with dust boots and PTFE / SUS304 stainless braided lines for trail dust, vibration, and heat cycling.
Direct-Mount Series caliper configured for the Ford Bronco and Bronco Raptor (U725) front axle — not a universal bracket workaround.
The included pads run a 0–600 °C operating range with an average μ of 0.38, tuned for loaded trail and overland use rather than peak track bite.

For 2021-2026 Ford Bronco (U725) and 2022-2026 Ford Bronco Raptor (U725), the correct OR6 rotor specification is Ø340 mm × 32 mm. Do not use the older 335 / 345 / 355 mm × 34 mm option layout for this application.
2 × OR6 forged 6-piston front calipers, left/right specific.
Brake pads for both front calipers, rated 0–600 °C and intended for iron / steel rotors.
2 × one-piece front rotors, Ø340 mm × 32 mm, heat-treated high-carbon cast iron, internally vented and left/right specific.
2 × vehicle-specific stainless braided brake lines with PTFE inner liner, SUS304 braid, and PVC protective outer sheath.
Vehicle-specific direct-mount hardware for Ford Bronco / Bronco Raptor (U725) front-axle installation.
Direct-Mount Series uses one-piece rotors and direct-mount calipers. Rotor Hats and Caliper Brackets are not included because they are not used on this OR6 application.
OR6 calipers require 17 in or larger wheels with a minimum 91 mm spoke clearance. Most 17 in off-road wheels with open spoke designs clear, but wheel diameter alone is not enough — confirm your specific spoke shape, offset, and inner barrel profile before ordering.
17 in or larger wheels are required.
Minimum spoke clearance: 91 mm. Confirm the wheel's inner spoke geometry against the caliper outline before installation.
Application: 2021-2026 Ford Bronco (U725) and 2022-2026 Ford Bronco Raptor (U725), front axle, with Ø340 mm × 32 mm rotor specification.

Yes. This listing is the OR6 front axle big brake kit for Ford Bronco and Bronco Raptor (U725). It does not include rear hardware.
The included pads run a 0–600 °C operating range with an average μ of 0.38, tuned for predictable modulation on loaded trail and overland use rather than peak track bite.
Yes. A proper bedding-in procedure is required to transfer pad material to the rotor face and stabilize friction before heavy use or long descents.
Yes. The kit includes three-layer stainless-steel braided lines with PTFE inner liner, SUS304 stainless-steel braid, and PVC protective outer sheath. Caliper-side and chassis-side fittings are vehicle-specific.
