Peterbilt Trelleborg Style - 4 Bolt - Caterpillar or Cummins - Taper Flywheel Housing

Upgrade your 2017 or newer Peterbilt truck with the Kustom Truck Rear Engine Mount Bracket Kit, designed for Cummins or Caterpillar engines with a 10-degree tapered flywheel housing and Trelleborg style 4-bolt Paccar frame mounts. These powdercoated engine-side brackets serve as OEM replacements or are ideal for engine conversions, ensuring secure engine alignment and effective vibration isolation when paired with corresponding 4-bolt Trelleborg style frame mounts (e.g., Kustom Truck P/N 19917011 or similar). The kit includes two rear engine mount brackets, Grade 8 bolts, flat washers, and nylock nuts, and Grade 10.9 flange bolts to attach the brackets to the flywheel housing and secure them to the frame-side brackets. Perfect for mechanics and fleet owners maintaining or upgrading Peterbilt models like 389, 388, 386, or 367, this kit supports custom builds, fleet applications, and engine swaps. 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); confirm compatibility with your Peterbilt truck’s frame mounts by contacting Kustom Truck.
