2008-2021 Toyota Land Cruiser 200 & 2008-2021 Lexus LX570 AR4 Direct-Mount Rear Big Brake Kit
The TTSPORT AR4 Rear Big Brake Kit is a Direct-Mount Series rear-axle upgrade for 2008-2021 Toyota Land Cruiser 200 and 2008-2021 Lexus LX570. It pairs a 4-piston forged aluminum rear caliper with Ø365 mm × 28 mm internally vented rear rotors, stainless-steel braided lines, and vehicle-specific fittings to improve rear-axle braking balance for loaded SUVs, towing, long descents, and matched front + rear brake builds.
Why Toyota LC200 & Lexus LX570 Builders Choose the AR4
Loaded LC200 and LX570 builds running larger tires, bumpers, drawers, roof loads, or trailer weight ask more from the rear brakes than stock hardware was designed to handle. The AR4 rear kit adds rear rotor mass, rear piston area, and firmer line response to help balance braking instead of forcing the front axle to do nearly all the work.
4-Piston Forged Caliper
Two-piece forged aluminum caliper body with 30 mm × 2 / 34 mm × 2 two-piece heat-insulated pistons and dust boots.
32.3 cm² Piston Area
32.3 cm² total piston area per caliper helps restore rear-axle braking contribution on heavier SUV builds.
Ø365 mm × 28 mm Rear Rotor
One-piece internally vented rear rotor adds rear thermal capacity with a directional curved-slot face pattern.
Vehicle-Specific Brake Lines
PTFE inner liner, SUS304 stainless-steel braid, and PVC protective outer sheath help reduce hose expansion and improve pedal consistency.
Balanced Rear Upgrade
Designed for towing, loaded overland driving, and matched front + rear brake builds without overpowering the rear axle.

Doggy getting warmed up to his latest toy
Size Name: Large, Style Name: Octopus, Size Name: Large, Style Name: Octopus
This is a huge push toy for the size of my chihuahua. He gets a bit overwhelmed by the size at first but slowly warmed up to it.
Can foresee he will be playing with this toy for a long time. Had quite a few toys from GoPet. Most of it still going strong after months of play.

Eyes on toy are dangerous for dogs
Size Name: Mini, Style Name: Checkers, Size Name: Mini, Style Name: Checkers
I’ve bought several Go Dog products and they have all been excellent. My dog adores the textures, robustness and squeak, plus the imaginative design.
This one though is sadly not we’ll though out because of the eyes. Fragile and easy to pull off the dog can open them and eat the stuffing and become Ill. As happened Christmas 2021. Please take heed and change the eyes on this product. Thanks

So many squeaky bits
Size Name: Large, Style Name: Octopus
While my dog destroyed the main squeaky bit in the body, most of the legs so have squeaky bits too so it keeps him entertained. Well recommended.
