2009-2023 Toyota Land Cruiser Prado, 2012-2017 Lexus GX400 & 2010-2023 Lexus GX460 AR6 Direct-Mount Front Big Brake Kit
The TTSPORT AR6 Direct-Mount Series front big brake kit is engineered for Toyota Land Cruiser Prado / LC150 / J150, Lexus GX400, and Lexus GX460 builds that need stronger front-axle braking under towing, added weight, larger tires, armor, roof loads, and repeated downhill use. It pairs a forged 6-piston caliper with Ø362 mm × 32 mm two-piece front rotor assemblies, stainless-steel braided lines, and vehicle-specific fittings for firm, predictable pedal response.
Why Toyota LC150 Prado, Lexus GX400 & GX460 Builders Choose the AR6
Heavy body-on-frame SUVs generate serious front-axle brake load when fitted with larger tires, steel bumpers, drawers, roof gear, trailers, or recovery equipment. The AR6 adds caliper stiffness, piston area, rotor diameter, and thermal capacity while keeping the system direct-mount and vehicle-specific.
6-Piston Forged Caliper
Two-piece forged aluminum body with 30 mm × 2 / 34 mm × 2 / 38 mm × 2 heat-insulated pistons and dust boots.
55.0 cm² Piston Area
55.0 cm² total piston area per caliper helps deliver controlled clamp force for heavier front-axle braking loads.
Two-Piece Rotor Assembly
Ø362 mm × 32 mm internally vented front rotor assembly with fixed mounting, directional design, and curved-slot face pattern.
102 mm Spoke Clearance
AR6 requires 17 in or larger wheels and at least 102 mm of spoke clearance to the front caliper.
Stainless Braided Lines
PTFE inner liner, SUS304 stainless-steel braid, and PVC protective outer sheath help reduce hose expansion under braking load.

2. Spoke Clearance
Minimum spoke clearance: 102 mm. Check spoke shape, offset, spacer use, and inner barrel profile before ordering.
3. Vehicle Model

LC150 Prado, GX400 & GX460 AR6 Front Big Brake Kit FAQ
Will this AR6 front kit fit Toyota LC150 Prado, Lexus GX400 and Lexus GX460?
Yes. This AR6 Direct-Mount front kit is configured for 2009-2023 Toyota Land Cruiser Prado / LC150 / J150, 2012-2017 Lexus GX400, and 2010-2023 Lexus GX460. The correct front rotor specification is Ø362 mm × 32 mm.
What axle and rotor size does this AR6 kit use?
This is a front-axle kit using Ø362 mm × 32 mm two-piece, internally vented, directional front rotor assemblies with a curved-slot face pattern.
What wheel size and spoke clearance are required?
17 in or larger wheels are required, with at least 102 mm minimum spoke clearance to the front caliper. Wheel diameter alone is not enough; spoke shape, offset, spacer use, and inner barrel profile must be checked before ordering.
Is the AR6 rotor one-piece or two-piece?
The AR6 uses a Ø362 mm × 32 mm two-piece front rotor assembly. Do not describe this application as a one-piece rotor setup.
Does this kit use caliper brackets?
No. This is a Direct-Mount Series AR6 application with direct-mount front calipers and vehicle-specific front mounting geometry. Caliper brackets are not used on this configuration.
Are the included pads street-friendly?
Yes. The included pads operate from 0–600 °C with an average μ of 0.38, suitable for street driving, towing, and loaded SUV use on iron or steel rotors.
Do I need a rear upgrade as well?
This is a front-axle kit. Many owners run it with the OE rear setup, but a matched rear upgrade is recommended for heavily loaded, towing, or overlanding builds. Contact TTSPORT for axle-balanced recommendations.
Do I need to bed the brakes in?
Yes. A proper bedding-in procedure is required to transfer pad material evenly to the rotor face and reach stable braking performance.

My doggo's go-to toy!
It's not the most durable of toys (she's on her third in five years) but I will buy her as many as she needs because she is OBSESSED with it!

Defective toy and inconsistent quality.
Size: X-Large, Color: Raccoon, Size: X-Large, Color: Raccoon
My initial review was 5 stars based on my experience with a previous order (blue raccoon) and the fact my puppy was immediately interested in it. However, I did not give it to her to play with until this past Friday (May 21, 2026) because she had the first one I bought. In a matter of 2 days the seam on the back and at the base of the head unraveled and all of the stuffing was scattered all over the room. I thought I’d found some good, high quality, toys for her but apparently this one was defective because the first one had had a lot of use and I’d still in decent shape. This is too much money to pay for a dog toy that only lasts a day or two so be advised they aren’t all good.

Bigger, louder, crinklier, softer, than expected!
Size: X-Large, Color: Rabbit
My dog was gifted a collection of used toys and he really likes a very long stuffed pig which, unfortunately, another dog that is a destructive chewer, totally destroyed. I decided to break down and buy him another long stuffed toy today and since he's always blissfully watching rabbits in the yard and neighborhood I chose the rabbit version. This thing is huge which is great for him- he's 62 lbs and 7 months old and only half grown. He loves it, it has multiple LOUD squeakers, lots of crinkly spots, and fun ears/legs to grab hold off. He's a big fan and it's made with K9 Tuff Guard which LASTS. Super soft and easy to wash.
Update after 2 months- easy to wash and looks new after a washing. very durable so far, standing up to indoor and outdoor use. He is not a destructive chewer but whips them around, tramples on them, steps on them while running top speed and chomps on the annoying squeaker for hours. one squeaker has a hole and its tune is now slightly muted (thank god)

It’s been several months and all 3 still intact!
I have to be very selective because MOST toys labled recommended for “aggressive chewer” last about 20 minutes. Not kidding. These are the real deal. I’ve had these for several months now and all 3 are shockingly still completely intact and look like they did the day I got them.
