2024-2026 Toyota Land Cruiser Prado (LC250) & 2024-2026 Lexus GX550 7642TK Direct-Mount Front Big Brake Kit
The TTSPORT 7642TK is a Direct-Mount Series front big brake kit engineered for 2024-2026 Toyota Land Cruiser Prado (LC250) and 2024-2026 Lexus GX550. It pairs a forged 6-piston caliper with Ø345 mm × 32 mm heat-treated high-carbon cast-iron rotors to restore front-axle stopping margin on heavier overland, tow, and trail builds.
Why LC250 Prado & GX550 Builders Choose the 7642TK
Once you add 35s, sliders, a bumper, drawers, recovery gear, or a trailer, the factory front brakes work harder on every descent and freeway stop. The 7642TK adds piston area, rotor mass, and stainless-braided lines so pedal feel and heat capacity stay predictable when the truck is loaded.
Two-Piece Forged Aluminum Caliper
6-piston caliper, 3.8 kg per caliper without pads, built for front-axle stopping margin on heavier builds.
63.5 cm² Piston Area
34 mm × 2 and 38 mm × 4 pistons deliver 63.5 cm² total piston area per caliper.
Application-Correct Rotor Size
2024-2026 Toyota Land Cruiser Prado (LC250) and 2024-2026 Lexus GX550 use the 7642TK Ø345 mm × 32 mm front rotor specification.
Three-Layer Braided Lines
PTFE inner liner, SUS304 stainless-steel braid, and PVC protective outer sheath help maintain firm pedal feel under load.
Road, Tow & Trail Use
Pad operating window of 0–600 °C with average μ 0.38, suited to mixed road, tow, and trail use.

Quality good, price not.

I guess that's what you get for not having a mainstream HP brand printer like everyone and their brother

Not their finest hour

Well, the printer ink is OK as always, but, the order arrived late. I guess 2 day shipping is a thing of the past with Amazon.

Expensive but the best
Size: 2 Count (Pack of 1)
So expensive for this ink. I must admit however it’s also the best out there. If they took away all of the advertisement on the package and just shipped simple it might be less expensive to the consumers. I don’t need all the jazz. Just the performance is all I am interested in.

It's Expensive
Size: 2 Count (Pack of 1)
I bought the Epson printer that this ink goes with because it (the printer) was highly rated. Once I got it, I don't agree with the rating but that is for another review.
The ink is perfectly fine and expensive which all ink cartridges are. One just pays what one has to.
