2021-2026 Ford Bronco & 2022-2026 Bronco Raptor PB6 Direct-Mount Front Big Brake Kit
The TTSPORT PB6 is a Direct-Mount Series front big brake kit engineered for the Ford Bronco (U725) and Ford Bronco Raptor (U725). It pairs a 6-piston forged aluminum caliper with Ø340 mm × 34 mm internally vented one-piece high-carbon iron rotors, stainless-steel braided brake lines, and vehicle-specific fittings for stronger front-axle braking under larger tires, armor, trail use, towing, and repeated downhill braking.
Why Ford Bronco & Bronco Raptor Builders Choose the PB6
The U725 Bronco platform is often modified with 35–37 in tires, steel bumpers, recovery gear, roof loads, and trail equipment. The PB6 adds front-axle piston area, rotor mass, and stainless-braided line response while keeping the installation vehicle-specific and direct-mount.
6-Piston Forged Caliper
Two-piece forged aluminum caliper with 28 mm × 2 / 34 mm × 2 / 40 mm × 2 racing pistons.
55.6 cm² Piston Area
55.6 cm² total piston area per caliper helps deliver controlled front-axle clamp force for heavier Bronco builds.
Ø340 mm × 34 mm One-Piece Rotor
Heat-treated high-carbon cast-iron rotor, internally vented, fixed, directional left/right specific, with curved slot / Grain Slot face pattern.
97 mm Spoke Clearance
Recommended for 17 in or larger wheels with at least 97 mm minimum spoke clearance.
Racing Piston Service Note
PB6 uses racing pistons without dust boots. After mud, sand, deep water, or salted-road driving, inspect and clean the piston area as part of normal maintenance.

Squeaker inside toy breaks after 2 days
Size: Mini, Color: Gator (Pink)
Bought for my 8 lb chihuahua for Christmas. I have 3 little girls. The youngest loves her toys and of course she took this one over immediately. She just loved everything about it. The material on the gator is amazingly durable and I believe would hold up for a good while. The squeaker inside the toy however, broke after 2 days of my girl playing with it. It's now a noiseless toy that she does not like too much as it does not squeak because it only had the one squeaker in it.
I would recommend that 2 squeakers be inserted into this gator. I would not purchase again due to the longevity of the squeaker...only lasted 2 days.

My dog loves these toys.
Size: Mini, Color: Gator (Pink)
Not a huge toy, nor is my dog. But we have lots of goDog toys. Practically indestructible and my dog likes to carry these in his mouth and bring them onto the foot of our bed. Brilliant colors and good squeaker but my dog is afraid of the squeak. Fair value for cost.

When they said strong...
...they weren't kidding. Our pup would chew through everything she could get her sharks teeth into. Like my arms. Nothing lasted as long as a week or maybe two. But she has had Dino for months now. She loves him. He is the go to toy for when she wants to play tug. The material used to make this toy is every bit as strong as the seller claims. I will definitely buy from them again. And I will not wait for this one to rip. I may be waiting a long time. If your pup likes to tear stuff apart, feel safe in buying this toy,
UPDATE: 2/9/2023
Dino finally succumbed to the torture. His back ripped open and despite trying to repair him with ordinary thread he couldn't withstand the pressure, His stuffing was removed and spread all over the living room. Completely emptied he is still a good toy. Strong enough to withstand the forceful play of tug-o-war.
Only thing I would suggest is to use something stronger when closing his back. The rest of him is great. I will be replacing him soon.
