2022-2026 Toyota Land Cruiser 300 (LC300) & 2022-2026 Lexus LX600 OR6 Direct-Mount Front Big Brake Kit
The TTSPORT OR6 front big brake kit is built for loaded Toyota Land Cruiser 300 and Lexus LX600 builds — armor, winches, long-range fuel, drawers, fridges, roof tents, trailer tongue weight, and 33–35" tire packages. A forged 6-piston direct-mount caliper, Ø345 mm × 34 mm heat-treated high-carbon rotors, stainless lines, and a high-temperature pad compound work together to keep the pedal predictable when the truck is heavy, hot, and working downhill.
Why LC300 & LX600 Builders Choose the OR6
Consistent Pedal Feel
Two-piece forged aluminum caliper, 6-piston layout, and heat-insulated pistons hold a linear pedal under sustained braking.
Application-Correct Rotor Size
Toyota LC300 and Lexus LX600 use the OR6 Ø345 mm × 34 mm front rotor specification.
Direct-Mount Application
Direct-Mount Series uses vehicle-specific mounting geometry and brake-line fittings for the LC300 and LX600 platform.
Street-to-Trail Pad Window
Pad compound operates from 0–600 °C with an average friction coefficient of 0.38 for loaded highway stops, mountain passes, and trailer towing.
Long-Grade Thermal Control
Internally vented, directional high-carbon rotors manage repeated heat cycles from mountain passes and washboard descents.

2. Spoke Clearance
Minimum spoke clearance: 91 mm. Wheel diameter alone is not enough; spoke shape, offset, and barrel profile affect real clearance.

Any toy that last over 2 days with a Belgian deserves 5 stars.
I purchased this for my pup's 2nd birthday. She loves it. Within in 24hrs all the tabs were chewed off but the ball itself is still holding up. She plays volleyball with it, catch, Chase, and chews on it. It is going on a month and it is still around. Thank you. It is difficult to find a toy that lasts with a Belgian and they are hyper dogs that need toys.

A MUST for busy dogs!!
Color: Green, Size: Medium
The tags are a hit! My border collie entertains herself with this ball. The longer black tag is PERFECT for her to grasp it and fling it in the air.
