Optimize your Peterbilt truck’s engine mounting system with the Kustom Truck Rear Engine Mount Bracket Kit, designed for Caterpillar C15 or 3406E engines or Cummins ISX engines with a 10-degree tapered flywheel housing. These painted engine-side brackets serve as OEM replacements for 2012 and older Peterbilt trucks equipped with 2-hole donut style frame mounts or are essential for engine swaps in any Peterbilt model year when paired with 2-hole donut style frame mounts (e.g., Kustom Truck P/N 19917009 or similar) 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 Caterpillar or Cummins side-mounted flywheel bracket system, this kit requires swapping 2-hole donut style frame mounts to ensure compatibility. The kit includes two rear engine mount brackets and Grade 8 bolts, flat washers, and lock washers to attach the brackets to the side of the flywheel housing, providing secure engine alignment and effective vibration isolation. Perfect for mechanics and fleet owners upgrading models like Peterbilt 389, 388, 386, or 367, this kit excels in custom builds, fleet maintenance, and engine swap projects. Note: Engine mounts are only compatible with the corresponding frame mounts (i.e., 2-hole donut style frame mounts are only compatible with 2-hole donut style engine mounts); confirm compatibility with your Peterbilt truck’s frame mounts and bushings by contacting Kustom Truck.
