Upgrade your cooling system's stability with the extreme durability of ATRO High-Temp Polyurethane.
The ATRO EM75-61001-HT is a premium Charge Air Cooler (CAC) Mount Kit specifically engineered for late-model Kenworth and Peterbilt trucks. Unlike standard rubber mounts that crack and degrade under under-hood heat, this High-Temp (HT) kit uses ATRO’s proprietary polyurethane to provide superior vibration dampening and a significantly longer service life.
This kit is designed for the rigorous environment of the '08–'10 Kenworth T800 and Peterbilt 389, as well as a wide range of newer aerodynamic models. It provides all the hardware and bushings necessary to securely mount the charge air cooler, preventing the cracked headers and boost leaks often caused by excessive vibration and failed OEM rubber.
Each kit services the cooler with heavy-duty components:
(4) Polyurethane Mount Bushings: High-temp rated for maximum longevity.
(4) Polyurethane Washers: Provides a cushioned seal and prevents metal-on-metal wear.
(4) Flange Bolts: Zinc-coated for corrosion resistance.
(4) Flange Locknuts: Ensures a secure, vibration-proof hold.
(4) Flat Washers: Distributes pressure evenly across the mounting surface.
Primarily used for Charge Air Cooler Mounting on:
Kenworth: T370, T440, T470, T660, T680, T700, T800 (2008-2010), T880, T2000, W900
Peterbilt: 389, 365, 367, 567, 579, 587

Chemical & Heat Resistant: ATRO’s High-Temp formula is unaffected by oil, grease, and the extreme temperatures found in the engine compartment.
Maintains Alignment: Prevents the CAC from shifting, protecting your boots and clamps from premature failure.
Direct OEM Upgrade: Replaces the standard N4751001 series with a more durable material that won't rot or "mushroom" over time.
