For Toyota 4Runner (2010+) & Lexus GX460 (2010+) — 6-Piston / 1-Piece Rotor Kit
Powerbrake’s X-Line 4x4 Big Brake Kit is the ultimate braking upgrade for modified overland vehicles. Featuring race-bred calipers, directional rotors, and Dakar Rally-proven tech, this bolt-on kit transforms your 4Runner or GX460’s braking performance under load, heat, and rugged terrain.
Key Features
- Billet 6-Piston Calipers — lightweight, rigid, and pre-loaded with performance pads
- 1-Piece 350x34mm Directional Rotors — 48 curved cooling vanes with MTR paint
- Billet Caliper Mounting Brackets — precision fitment, no guesswork
- Stainless Steel Braided Brake Lines included

Built for Overland Performance
Modern 4x4s carry more weight than ever — rooftop tents, bumpers, long-range tanks, drawer systems, and larger tires all reduce braking performance. This kit compensates for the extra load with:
- Reduced stopping distances under load
- Drastically reduced brake fade under high heat
- Improved pedal feel and modulation
- Race-proven engineering trusted by Dakar and FIA Cross Country teams
Kit Includes
- (2) 6-piston billet aluminum calipers (pads pre-installed)
- (2) 1-piece 350x34mm rotors with directional cooling vanes
- Billet mounting brackets
- Stainless steel braided brake lines
- Mounting hardware and full instructions
- Note: Brake fluid not included
