Engine Rocker Arm Overview

The Melling MR-1340 is a standard replacement engine rocker arm built for a wide range of domestic and import applications. It uses a roller design, cast steel construction, and a shaft mounting style to match the specified valvetrain setup.

Compatible with many Buick, Chevrolet, Cadillac, GMC, Pontiac, Saturn, Saab, and Oldsmobile applications, this rocker arm is listed for stock configurations and select exhaust applications. The MR-1340 is a fitment-based choice for owners servicing GM and related platforms such as the Chevrolet Malibu, Buick LaCrosse, and Cadillac CTS.

  • Roller rocker arm design for reduced valvetrain friction
  • Cast steel construction with anti-rust finish
  • Self-aligning design for specified engine assemblies
  • Shaft-mounted configuration for direct replacement use
  • Standard replacement grade for rebuild and service work

Detailed Application Notes

Melling MR-1340 is intended for engines that call for a self-aligning, shaft-mounted roller rocker arm. The cast steel body and anti-rust finish support service use in rebuilds and repairs where the original valvetrain geometry must be maintained. This part number, MR-1340, is listed across multiple GM-family platforms including Chevrolet Malibu, Buick Regal, and Cadillac CTS applications.

Common Problems This Part Can Address

  • Worn or noisy rocker arm operation
  • Loss of proper valvetrain motion from a damaged rocker arm
  • Corrosion on an existing rocker arm surface
  • Service replacement during engine rebuilds
  • Fitment issues when the original shaft-mounted rocker arm is no longer serviceable

Installation Notes and Tips

Verify engine code, valvetrain layout, and application notes before installation. The MR-1340 is specified for shaft-mounted, self-aligning use, so the matching rocker arm geometry and related components must be confirmed during service. Melling recommends replacing rocker arms and related components during engine rebuilds to maintain long-term engine performance.
