Top Features
| Feature | Buyer Benefit |
|---|---|
| Smooth & Fast Braking | Disc design paired with premium ceramic pads provides shorter, controlled stopping distances. |
| All-Stainless Build | Stainless rotors, calipers, and brackets fight rust and corrosion in harsh marine, saltwater, or winter environments. |
| Vented Slip-On Rotor | Integrated drainage holes shed heat and moisture quickly to maintain performance and extend pad life. |
| Hassle-Free Install | Slip-on rotor mounts directly over standard idler hubs without needing a complete hub replacement. |
Important Fitment Note: Verify all measurements, specifications, mounting points, side orientation, connector style, compatibility details, and included components before installation. OEM or platform references describe application fitment only unless OEM status is specifically verified.
R&P Knowledge Hub
Compatibility: Designed for standard 7,000 lb capacity trailer axles utilizing 5-bolt brake mounting flanges and 8-bolt wheel hubs (8 on 6-1/2"). Verify wheel stud diameter (1/2") and rim clearance prior to ordering.
Vehicle / System Fit: Ideal for heavy-duty marine, boat, livestock, equipment, and utility trailers operating in high-corrosion or heavy-load environments.
Installation Notes: Slip-on rotors slide directly over existing idler hubs with matching bolt patterns, significantly reducing installation time and eliminating the need to pack new inner wheel bearings or install new hub grease seals.
Performance Insight: Vented rotor engineering combined with 2-1/2" diameter pistons maximizes clamping force while rapidly shedding heat and water, minimizing fade under continuous heavy braking.
Features
Stops Smooth and Fast
Disc design with ceramic pads gives shorter, more controlled braking performance under heavy loads.
Fights Rust and Corrosion
All-stainless rotors, calipers, and brackets stay strong and resist degradation in saltwater or snow exposure.
Runs Cooler for Longer Life
Vented, slip-on rotors with drainage holes quickly shed heat and moisture to prevent brake fade.
Installs With Less Hassle
Slip-on rotors fit directly over standard idler hubs—no full hub teardown or replacement required.
Built for Heavy Loads
Precision-rated for 7,000-lb axles with robust 13-1/8" rotors, 2-1/2" pistons, and 8 on 6-1/2" bolt configuration.
Simplifies Maintenance
Laser-etched caliper instructions provide clear step-by-step guidance for bleeding lines and pad changes.
