Toyota 4Runner (4th Gen 4WD, Non-Sport) M-Line Caliper Upgrade Kit (03-09)

Powerbrake M-Line Performance Caliper Kit – Front – Toyota 4Runner (4th Gen 4WD, Non-Sport)

Enhanced performance without the complexity of a full big brake conversion.

For 4th Gen 4Runner models using the 319mm front rotor platform. Not for Sport models using the larger factory brake package.

Powerbrake M-Line kits improve braking feel, clamping efficiency, and overall control while maintaining compatibility with the OEM-sized rotor platform. This makes M-Line the ideal upgrade for vehicles with added weight, larger tires, or more demanding real-world use.

• High-performance 6-piston Powerbrake M-Line calipers
• High-performance brake pads included
• Optional matched Powerbrake D-Line rotor kit available at package pricing
• Designed for straightforward installation and excellent daily drivability

M-Line is a smart next step for customers who want more braking control and confidence without moving to a full larger-diameter rotor system.
