Detailed Description

Built for rear brake service on Chevrolet P30, Chevrolet G30, GMC P3500, and GMC G3500 platforms, the Raybestos R-Line 5925R rotor is specified for vehicles that require a conventional, solid disc brake rotor. Its 349.100 mm outside diameter, 39.000 mm nominal thickness, and 37.200 mm discard thickness provide the dimensional reference points needed when replacing a worn rear rotor. The 16.750 mm mounting bolt hole diameter and 184.150 mm bolt circle diameter support proper hub alignment on the listed applications.

Raybestos R-Line parts are positioned for straightforward replacement work where accurate dimensions matter. If you are servicing a rear brake rotor on a Chevrolet P30 or GMC P3500, the 5925R gives you the fitment and sizing details needed to match the original brake configuration.

What This Rotor Helps Address

  • Brake pulsation caused by rotor wear or thickness variation
  • Scoring, grooves, or heat checking on the rear braking surface
  • Rotor replacement needs during rear brake service on heavy-duty vans and chassis applications
  • Fitment issues when the original rotor uses a 10-bolt, conventional solid design
  • Dimensional mismatch on Chevrolet P30, Chevrolet G30, GMC P3500, and GMC G3500 rear brake systems

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, center hole diameter, and overall height against the removed part before installation. Clean the hub mounting surface thoroughly so the new rotor seats flat, and inspect pads, calipers, and wheel bearings for wear before completing the brake job. For best results, confirm the rear brake configuration on your Chevrolet P30, GMC P3500, Chevrolet G30, or GMC G3500 before ordering the Raybestos 5925R.

Quality Assurance

The Raybestos R-Line 5925R is a specification-based replacement rotor built to match the listed application dimensions for rear brake service. Raybestos is a long-established brake parts brand, and the R-Line product line focuses on direct replacement coverage for common service applications.
