54mm (OEM size) Cam Bushing Set

54 mm OEM-Size Cam Bushing Set

Standard 54 mm camshaft bushings for Cummins engines running factory-diameter cam journals. They restore correct journal clearance during a rebuild and give the camshaft proper support — and they are required if a steel camshaft is going into a cast iron block.

Key Features

• Standard 54 mm size, for factory 2.124" cam journals
• Restores correct journal clearance on a rebuild
• Required for steel camshafts and for springs over 450 lb nose pressure
• Made in the USA

Installation Notes

• Professional installation and camshaft-clearance verification required
• 12-valve engines typically use one bearing on the first journal; some common-rail engines use one on the first and one on the seventh

Fitment

1989–2018 Dodge and Ram 5.9L and 6.7L Cummins using the standard 54 mm cam journal.
