Optimize your Peterbilt truck’s engine mounting system with the Kustom Truck Frame Side Rear Engine Mount Kit, designed for 2-hole donut style flywheel mounts compatible with Caterpillar, Cummins, or Detroit engines. These frame-side brackets serve as OEM replacements for 2012 and older Peterbilt trucks equipped with 2-hole donut style frame mounts or are ideal for engine swaps in any Peterbilt model year when paired with corresponding 2-hole donut style engine mounts (e.g., Kustom Truck P/N 19317001, 19917008, 19117009) and bushings (e.g., Kustom Truck P/N 19917002 or similar). Ideal for replacing Paccar engines, which use a unique rear-mounted flywheel bracket system incompatible with side-mounted Caterpillar, Cummins, or Detroit flywheel bracket systems, this kit requires swapping Trelleborg (2-bolt or 4-bolt) or Paccar frame mounts with 2-hole donut style frame mounts (e.g., Kustom Truck P/N 19917009 or similar) to ensure compatibility. The kit includes two frame-side rear engine mounts, which can be rotated 180 degrees to accommodate engine installation when used with the specified Kustom Truck engine-side brackets. For Caterpillar, Cummins, or Detroit engines with Kustom Truck P/N 19317001, 19917008, or 19117009, mount the bracket with the #2 at the top; for Detroit Diesel engines with OEM Flywheel brackets, mount with the #1 at the top. Orientation may differ with non-Kustom Truck flywheel housing brackets. Perfect for mechanics and fleet owners upgrading models like Peterbilt 389, 388, 386, 379 or 367, this kit excels in custom builds, fleet maintenance, and engine swap projects. Note: These mounts are only compatible with corresponding two-hole flywheel housing mounts (i.e., two-hole donut style frame mounts are only compatible with two-hole donut style engine mounts); confirm compatibility with your Peterbilt truck’s engine mounts and bushing by contacting Kustom Truck.
