Xiaoyudou Exhaust Mount Bushing Kit M136109K for Peterbilt & Kenworth — Poly Bushings, Shaft & E‑clips

The Xiaoyudou M136109K exhaust mount bushing kit secures and cushions your truck's exhaust assembly with a durable poly bushing, shaft, washers and E-clips engineered for Peterbilt and Kenworth models.

Built to replace worn or failing exhaust supports, this complete kit includes the exhaust mount, two poly bushings, a shaft, two washers and two E-clips. It is compatible with a wide range of heavy-duty trucks — including Peterbilt 348, 379, 388, 389 and Kenworth T600, T680, T800, W900 — and is intended to reduce excessive movement, vibration and metal-to-metal contact under highway conditions.

How does this kit improve exhaust stability and reduce noise?

The poly bushings absorb vibration and isolate the exhaust from the chassis, preventing chafing and lowering noise caused by metal contact. The included shaft and E-clips lock components in place so the mount maintains correct alignment over time.

• Poly bushing material resists degradation from heat, fluids, and road contaminants
• Shaft and E-clips provide positive retention to stop lateral movement
• Two washers help distribute load and prevent bushing pinch

Which truck models and applications does M136109K fit?

This kit is specified for common Peterbilt and Kenworth platforms; it fits typical exhaust mounting points for the listed models. Check your OEM part reference and mounting geometry to confirm compatibility before installation.

• Peterbilt: 348, 379, 388, 389
• Kenworth: T600, T680, T800, W900
• Supplies one mount and the full bushing hardware set for a single support location

What materials and durability features should I expect?

The bushings are made from a high-performance polymer chosen to withstand high temperatures, hydrocarbons and road debris better than conventional rubber. The metal shaft, washers, and E-clips are treated to resist corrosion so the assembly remains secure in demanding service.

• Heat- and fluid-resistant poly bushing for extended service life
• Metal shaft and clips engineered for repeated removal and reinstallation
• Designed to tolerate highway vibration and heavy-duty loading

How easy is installation and what comes in the package?

The kit arrives ready for a straightforward swap: remove the old mount, position the new poly bushing and mount, slide in the shaft, and secure with washers and E-clips. Basic hand tools are typically sufficient; no special presses are required for most installations.

• Contents: 1 exhaust mount, 2 bushings, 1 shaft, 2 washers, 2 E-clips
• Designed for bolt-on replacement at a single exhaust hanger location
• Installation generally requires common wrenches and pliers

It’s a practical choice when you want to restore proper exhaust alignment, reduce noise from vibration, and avoid premature wear on adjacent components.
