Kodiak Stainless Disc Brake Kit – 13" Rotor – 8 on 6-1/2 – 7K Axle – 1/2" Bolts

Part Number: K71-2R-133-7-8-SSS

Premium Stainless Disc Brake System

Upgrade to Confident, Consistent Braking

This Kodiak stainless system delivers a major step up from drum brakes—stronger stopping power, smoother engagement, and long-term reliability in harsh environments.

High-Torque Braking

13" vented rotors paired with a 2-1/2" stainless piston deliver increased braking force—roughly 30% more than many standard systems.

Marine-Grade Durability

Full stainless steel construction resists corrosion with a 1,000-hour salt-spray rating—ideal for boat trailers and coastal environments.

Runs Cooler, Lasts Longer

Vented rotor design dissipates heat quickly, reducing brake fade and protecting components during long hauls or steep grades.

Balanced, Low-Drag Performance

Self-adjusting calipers apply even pressure and retract efficiently, reducing heat buildup and improving towing efficiency.

Simplified Installation & Service

Kodiak’s slip-on rotor design installs over your existing hub—no need to replace full hub assemblies. This makes conversions faster and maintenance significantly easier. When service is needed, rotors can be removed independently without disassembling the entire system.

Reinforced Mounting System

Heavy-duty stainless brackets feature enhanced embossing for improved thread engagement. The side-support design transfers braking forces into the bracket structure rather than the mounting bolts, increasing long-term reliability.

Where This Kit Excels
