Big Block Mopar Timing Cover Chrome

The PROFORM Big Block Mopar Timing Cover in chrome is a precision one-piece OEM replacement designed for big-block Mopar B-series and RB-series engine platforms, including the legendary 426 Hemi. This timing cover assembly arrives complete with integrated seal and timing tab, eliminating the need for secondary purchases and reducing installation time in the shop or field.

Built from steel with a bright chrome finish, this cover delivers both corrosion resistance and the classic aesthetic demanded by restorators and performance builders. The one-piece construction ensures proper bore concentricity and eliminates the fit variation issues that plague multi-piece alternatives. The included factory-specification seal maintains compression integrity and prevents oil seepage at the critical crankshaft interface. The timing tab positioning is factory-indexed, eliminating guesswork during installation and ensuring accurate ignition timing reference when using dial-back degree-wheel or magnetic timing methods.

This cover suits restoration projects where originality matters, as well as high-performance builds where reliable sealing and precise timing references are non-negotiable. Whether you're rebuilding a show truck, a street/strip combination, or diagnosing timing issues on existing big-block iron, this PROFORM unit provides confidence that the front end is sealed and indexed correctly.

PROFORM has positioned itself as a trusted supplier of Mopar performance and restoration parts, with particular strength in small-block and big-block engine timing and accessory covers. This timing cover maintains that reputation by adhering to original specifications while delivering modern manufacturing consistency.
