Detailed Description

The Melling MR-848 rocker arm is engineered for Pontiac valve train applications that call for a stock-style, shaft-mounted component. Its stamped steel construction and anti-rust finish provide a practical replacement option for rebuilds where original-style operation is required. This part number, MR-848, is listed for 1969-1970 Pontiac Bonneville, Catalina, Executive, Firebird, Grand Prix, GTO, Laurentian, LeMans, Parisienne, Tempest, and 1970 Pontiac Strato-Chief with the Ram Air IV engine and stock configuration. Melling also notes that rocker arms are offered for domestic and import applications, with material selection based on OEM design requirements.

Common Uses

• Worn rocker arm replacement during engine rebuilds
• Restoration of stock valve train geometry
• Correction of noisy or inconsistent valve train operation
• Replacement for damaged or fatigued stamped rocker arms

Installation Notes

Install MR-848 with the correct matching valve train components for the engine build. Melling recommends replacing rocker arms and related components during a rebuild to support long engine life and efficient performance. Verify shaft mounting style, self-aligning design, and application details before installation.

Quality Assurance

Made in the USA, the MR-848 follows Melling's standard replacement approach for engine valve train service. This part cross-references Monroe Shocks & Struts (e.g., 74-2848, R-383-4) for the same application.
