2022-2026 GWM Tank 500 OR6 Direct-Mount Front Big Brake Kit
The TTSPORT OR6 front big brake kit is built for loaded GWM Tank 500 builds — overland weight, larger all-terrain tires, armor, winch, roof equipment, passengers, and recovery gear. A forged 6-piston direct-mount caliper, Ø345 mm × 32 mm high-carbon cast-iron rotors, and stainless-steel braided lines deliver predictable pedal feel on long descents, washboard roads, and daily street use.
Why GWM Tank 500 Builders Choose the OR6
A built Tank 500 rarely weighs what it did from the factory. Add passengers, recovery gear, fridge, water, fuel cans, sliders, bumpers, winch, and 33–35 in tires, and the front brakes are working much harder on every grade. The OR6 kit raises clamp force and thermal headroom so the pedal stays consistent during repeated speed checks, slow technical descents, and long highway tows back to camp.
Forged 6-Piston Caliper
Two-piece forged aluminum body with 40 mm × 4 and 43 mm × 2 pistons for stable pressure under heavy vehicle load.
Heat-Insulated Pistons
One-piece heat-insulated pistons with dust boots help resist heat soak and keep trail grit away from the piston seal area.
High-Carbon One-Piece Rotors
Heat-treated high-carbon cast-iron rotors, internally vented, fixed, directional, and left/right specific.
Braided Brake Lines
PTFE inner liner, SUS304 stainless-steel braid, and PVC protective outer sheath help maintain firm pedal feel on rough access roads.
Direct-Mount Front Fitment
Direct-mount front configuration with vehicle-specific brake line fittings and no rotor hats or caliper brackets.

GWM Tank 500 OR6 Big Brake Kit FAQ
Will OR6 fit 2022-2026 GWM Tank 500?
Yes. This OR6 front kit is configured for 2022-2026 GWM Tank 500 applications. The correct rotor specification is Ø345 mm × 32 mm. Hi4-Z is not available.
Will this fit my GWM Tank 500 with stock 18-inch wheels?
OR6 requires 17 in or larger wheels with at least 91 mm of spoke clearance. Stock wheel clearance should still be verified with a clearance template before installation because spoke shape and barrel profile affect real fitment.
Does this OR6 kit fit the Tank 500 Hi4-Z?
No. The GWM Tank 500 OR6 application uses Ø345 mm × 32 mm front rotors, but Hi4-Z is not available.
What rotor size does this application use?
2022-2026 GWM Tank 500 uses Ø345 mm × 32 mm one-piece front rotors in the OR6 Direct-Mount Series. Do not use the older Ø380 / 405 mm × 34 mm rotor-option layout for this application.
Does this kit include rotor hats or caliper brackets?
No. This is a Direct-Mount Series OR6 application with one-piece rotors and direct-mount calipers. Rotor Hats and Caliper Brackets are not used on this configuration.
Is this kit suitable for a heavily built overland Tank 500?
Yes. The 6-piston forged caliper, Ø345 mm × 32 mm high-carbon vented rotors, and braided lines add clamp force and thermal capacity for trucks running armor, winch, roof equipment, added cargo, and larger tires.
Are the pads street-friendly and off-road friendly?
The included pads run 0–600 °C with an average μ of 0.38. They are balanced for mixed street, highway, towing, and off-road service and are intended for iron / steel rotors only.
Do I need to bed in the brakes?
Yes. A proper bedding-in procedure is required to transfer pad material evenly to the rotor face and reach stable friction performance.
What is included?
The kit includes OR6 forged 6-piston front calipers, Ø345 mm × 32 mm one-piece directional rotors, brake pads, vehicle-specific stainless-braided brake hoses, and direct-mount hardware. Rotor Hats and Caliper Brackets are not used on this Direct-Mount Series configuration.

Durable, even for a Great Dane!
Color: Ultra, Size: XXL
I've bought many tennis ball sized ChuckIt balls in the past (for medium sized dogs we've owned), so when we knew we were going to be babysitting our daughter's Great Dane, I bought a bigger one for her. The 4" is perfect for her! She plays catch with it, but also likes to gnaw on it. It holds up great!

Another great product from Chuckit!
Color: Ultra, Size: XL
Exactly the high quality that I've come to expect from Chuckit! The plastic/rubber used in their products is extremely tough yet gives enough that it's hard to actually pierce the it and tear apart. We have had Chuckit! Sticks and Balls with launcher for years and love them all. This particular ball is pretty big so my 45 pound pit mix struggles to pick it up but that's part of the fun for him. My 85 pound pit mix can pick it up no problem. The only "complaint" is that the two of them have been having so much fun with their new ball, they have already knocked something over and broke it.

Perfect for my mid size pit bull
Color: Ultra, Size: XL
Updating my review, the ball only lasted 5 days. I left the 5 stars because we had enough fun those 5 days to be worth the small price. She has dog has a lot of jaw strength, so I’m not surprised
We have a mid size foster pit bull. This ball is her favorite toy. It’s durable and the perfect size for her to play ball safely.

Good quality
Color: Ultra, Size: Large, Color: Ultra, Size: Large
Great quality. I purchased for my daughter’s dog who destroys all toys. This toy holds up. I didn’t realize it was a large and the chickit stick she had was a medium. The large ball ended up working out good for playing inside the house. The dog likes it a lot.
