2024-2026 Toyota Land Cruiser Prado (LC250) & 2024-2026 Lexus GX550 OR6 Direct-Mount Front Big Brake Kit
The TTSPORT OR6 front big brake kit is built for loaded Toyota LC250 Prado and Lexus GX550 overland and off-road builds — armor, winch, drawers, roof tent, larger tires, and real cargo weight. Forged 6-piston calipers and Ø345 mm × 34 mm heat-treated high-carbon rotors deliver predictable pedal feel on long descents, washboard, and mixed terrain.
Why LC250 Prado & GX550 Builders Choose the OR6
Predictable Pedal Under Heat
Two-piece forged aluminum caliper with one-piece heat-insulated pistons and dust boots helps resist fade on long grades.
Application-Correct Rotor Size
Toyota Land Cruiser Prado (LC250) and Lexus GX550 use the OR6 Ø345 mm × 34 mm front rotor specification.
Off-Road Service Focus
Internally vented, directional one-piece rotors plus stainless-steel braided lines support consistent response in dust, mud, and water crossings.
Larger Contact Patch Friendly
Sized to recover braking authority lost when running 33–35 in tires and heavier wheels.
Direct-Mount Installation
Direct-Mount Series uses vehicle-specific mounting geometry and brake-line fittings without rotor hats or caliper brackets.

Excellent Quality and Value
Color: Light Blue White Plaid, Size: Small
This shirt is an excellent value, looks great on my husband and comes out of the dryer looking perfect. However, I ordered this plaid and another plaid pattern and received 2 of this same plaid. I will seek out this brand in my future purchases for the high quality.
