Optimize your Peterbilt truck’s engine mounting system with the Kustom Truck Frame Side Rear Engine Mount Kit, designed for 4-bolt Trelleborg style Paccar frame mounts compatible with Cummins or Caterpillar engines. These painted frame-side brackets serve as OEM replacements for 2017 and newer Peterbilt trucks equipped with 4-bolt Trelleborg frame mounts or as upgrades for earlier model years (pre-2017 trucks with 2-hole donut style or 2-bolt Trelleborg frame mounts), provided the frame mounts and corresponding engine mounts are upgraded to 4-bolt Trelleborg style (e.g., Kustom Truck P/N 19917012). Ideal for engine swaps, including replacing Paccar engines, which use an incompatible rear-mounted flywheel bracket system, this kit requires swapping 2-hole donut, 2-bolt Trelleborg, or Paccar frame mounts with 4-bolt Trelleborg frame mounts to ensure compatibility with side-mounted Cummins or Caterpillar engine flywheel housing brackets. The kit includes two frame-side rear engine mounts and six shims for precise fitment and adjustment. 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., 4-bolt Trelleborg style frame mounts are only compatible with 4-bolt Trelleborg style engine mounts; 2-hole donut or 2-bolt Trelleborg frame mounts require matching engine mounts); confirm compatibility with your Peterbilt truck’s engine mounts by contacting Kustom Truck.
