The Powerbrake X-Line 4x4 big brake kit represents the pinnacle of brake upgrades globally for 4x4 vehicles, meticulously crafted using technology directly transferred from our championship-winning R-Line off-road racing systems. For over a decade, our race-proven brake systems have dominated the world's most challenging motorsport events, including multiple FIA Cross Country World Championships and the legendary Dakar Rally, across diverse terrains from blistering deserts to snow-blanketed forests.
The booming trend of customizing civilian 4x4 vehicles has created a pressing need for superior brake performance. Adventure seekers are loading their Tacomas with rooftop tents, bull bars, extended fuel storage, water reservoirs, battery setups, and oversized wheel and tire combinations - all of which substantially increase vehicle weight and compromise braking efficiency. Our X-Line kits provide enhanced braking performance, reduced brake fade, and superior pedal sensation and control that surpasses standard disc and pad upgrades.
Why Upgrade Your Tacoma Brakes?
Modern 4x4 customization significantly impacts braking performance through:
- Increased Vehicle Weight - Rooftop tents, storage systems, and additional equipment add substantial mass
- Larger Wheel/Tire Combinations - Heavier wheels create additional rotational mass affecting brake performance
- Enhanced Engine Performance - Supercharged vehicles generate higher speeds and increased brake temperatures
- Extended Stopping Distances - Factory brakes struggle with heavily loaded adventure-ready vehicles
Available Options
Stage-1 Kit
Perfect balance of performance enhancement and value, featuring single-piece discs with exceptional cooling capacity.
Stage-2 Kit
Ultimate civilian brake system utilizing dual-piece floating disc assemblies that bring you as close as possible to our World Championship-winning race brake technology.
