2022-2026 Toyota Tundra (XK70) & 2023-2026 Toyota Sequoia (XK80) 7642TK Direct-Mount Front Big Brake Kit
The TTSPORT 7642TK is a Direct-Mount Series front big brake kit engineered for 2022-2026 Toyota Tundra (XK70) and 2023-2026 Toyota Sequoia (XK80). It pairs a 6-piston forged aluminum caliper with Ø345 mm × 32 mm high-carbon iron rotors to add real braking margin under towing, payload, larger tires, and long mountain descents.
Why Toyota Tundra XK70 & Sequoia XK80 Builders Choose the 7642TK
Full-size Toyota trucks and SUVs put serious thermal and mechanical load on the front axle. Bigger tires, roof racks, trailers, and overland gear all push the factory front brakes into fade territory faster than most owners expect. 7642TK is sized to restore confident pedal feel and braking consistency without forcing a track-only setup.
63.5 cm² Piston Area
63.5 cm² total piston area per caliper helps increase front brake authority while keeping response controllable for daily, tow, and trail use.
Application-Correct Rotor Size
2022-2026 Toyota Tundra (XK70) and 2023-2026 Toyota Sequoia (XK80) use the 7642TK Ø345 mm × 32 mm front rotor specification.
Forged 6-Piston Caliper
Two-piece forged aluminum body with 34 mm × 2 and 38 mm × 4 heat-insulated pistons with dust boots.
High-Carbon Iron Rotors
One-piece, internally vented, directional rotors with Wave Slot face pattern for repeated braking and heat cycling.
Stainless-Steel Braided Lines
Three-layer PTFE / SUS304 / PVC lines help maintain firmer, more consistent pedal response under load.
