Designed for direct-fit applications on popular Peterbilt and Kenworth models, the M136109K assembly pairs a robust exhaust mount with engineered poly bushings and corrosion-resistant fasteners to withstand heat, road stress, and exhaust movement.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit improve exhaust stability on a working truck?\u003c\/h3\u003e\n\u003cp\u003eThe kit replaces worn or failing components that allow excessive exhaust travel and metal-to-metal contact, which can cause noise, stress on the piping, and faster wear of adjacent parts. The poly bushings absorb movement and hold the pipe in the intended position, restoring factory alignment and reducing strain at mounting points.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes a pre-assembled exhaust mount for straightforward installation.\u003c\/li\u003e\n  \u003cli\u003eTwo bushings engineered to resist heat and fluids better than rubber.\u003c\/li\u003e\n  \u003cli\u003eHardware pack (shaft, washers, E-clips) secures the bushing and keeps the assembly tight.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this fit my Peterbilt or Kenworth model?\u003c\/h3\u003e\n\u003cp\u003eThe M136109K is specified to fit multiple Peterbilt and Kenworth chassis used in medium and heavy-duty trucking. Confirm fitment by comparing the listed models to your truck: Peterbilt 348, 379, 388, 389 and Kenworth T600, T680, T800, W900.

The poly bushings resist cracking and swelling from oils and fluids, while metal parts are treated to lower corrosion risk. That translates to a longer service life and less frequent replacements under typical trucking conditions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePoly bushing material resists temperature and fluid degradation.\u003c\/li\u003e\n  \u003cli\u003eMetal mount and shaft designed to manage road vibration and torque.\u003c\/li\u003e\n  \u003cli\u003eWashers and E-clips provide secure fixation and ease of reassembly.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat comes in the box and what warranty is offered?\u003c\/h3\u003e\n\u003cp\u003eThe package arrives with everything needed to replace the exhaust mount and associated bushing hardware, which makes the job faster and cleaner.
