Raybestos R-Line 5020R Front Brake Rotor

The Raybestos R-Line 5020R is a vented front disc brake rotor built for classic truck and SUV applications that need a direct-fit replacement with the correct dimensions and bolt pattern. It is sized for 6-lug front brake setups and supports a wide range of Chevrolet, GMC, and Jeep models from the 1970s through early 1990s.

Product Details

Built for front brake service on Chevrolet Blazer, K10, K5 Blazer, K10 Suburban, V10, V10 Suburban, GMC Jimmy, K1500, K1500 Suburban, V1500, and Jeep Grand Wagoneer, Wagoneer, Cherokee, J10, CJ5, and CJ7 applications, this rotor matches the fitment requirements listed for each vehicle. The R-Line product line focuses on dependable replacement brake components for everyday repair work, and the 5020R follows that approach with the correct vented rotor configuration and OE-style dimensions for these older 6-stud platforms. This part cross-references Monroe Shocks & Struts (e.g., 5522) for the same application.

What This Rotor Helps Address

  • Brake pulsation caused by rotor wear or thickness variation
  • Grooving, scoring, or heat checking on the braking surface
  • Reduced braking consistency from a worn front rotor
  • Service replacement needs on 6-lug Chevrolet, GMC, and Jeep front brake systems
  • Fitment issues when the rotor must match the listed bolt circle and center bore

Installation Notes and Tips

Verify rotor dimensions, hub fit, and bolt pattern before installation. For best results, inspect pads, calipers, wheel bearings, and hub surfaces at the same time, since uneven wear or runout in related components can affect braking performance. This rotor is listed for front position use only, and fitment varies by year, make, model, and configuration notes such as 6 stud rotor or steering drive flange requirements on certain Jeep applications.

Quality Assurance

Raybestos brake components are built for service replacement applications, and the R-Line 5020R is specified with clear dimensional data to support accurate ordering for compatible Chevrolet Blazer, GMC Jimmy, and Jeep front brake repairs. Confirm the listed fitment notes for your vehicle before installation.
