The new LC250 and GX550 are designed to be used – and most owners don’t keep them at showroom weight.
Once you add steel bumpers, sliders, underbody protection, drawers, fridge, roof tent and extra fuel or water, the braking system is working much harder than the original spec assumed. The 7642TK front kit brings the front end up to par with that overland reality.
If your LC250 or GX550 is being built as a real long-range tourer rather than a school run SUV, 7642TK is the front brake upgrade that gives you back some margin on the way down as well as on the way up.
The 7642TK LC250/GX550 kit uses our heavy-load 6-piston architecture, tailored to the new platform’s chassis, weight and intended use.
