Product Description:
Industrial Injection Heavy Duty Charge Air Cooler Boot Kit • Part # C27601
Upgrade the reliability of your charge-air system with the Industrial Injection Heavy Duty Charge Air Cooler Boot Kit. Built for hard-working heavy-duty trucks, this kit delivers stronger, longer-lasting boost connections you can depend on. Each boot is made from durable 4-ply reinforced silicone for added strength and heat resistance, giving you a noticeable improvement over worn factory boots. The included spring-loaded T-bolt clamps apply even and consistent pressure to help prevent blowouts and boost leaks under load.
This kit fits most Heavy Duty applications such as Peterbilt, Kenworth, Freightliner, and other common Class-8 platforms that use standard CAC boot and clamp sizes. It’s an ideal replacement option for stock boots or a reliable upgrade for trucks seeing higher boost or demanding duty cycles.
Key Features
- 4-ply reinforced construction CAC boots for improved strength and heat resistance
- Heavy Duty spring-loaded T-bolt clamps for even and secure clamping pressure
- Designed to reduce boost leaks and increase long-term reliability
- Direct-fit upgrade for most Peterbilt, Kenworth, Freightliner, and other HD truck applications
- Suitable for stock or performance-modified applications
Fitment
This Heavy Duty Charge Air Cooler Boot Kit is built for applications that use 4-inch diameter, 6-inch length CAC boots. This size is commonly found on many Class-8 heavy-duty truck platforms, including:
- Peterbilt models using 4" CAC connections
- Kenworth models using 4" CAC connections
- Freightliner models using 4" CAC connections
- Additional heavy-duty trucks and vocational chassis equipped with 4" charge-air piping
- If your truck does not use a 4-inch CAC boot, this kit will not fit. Always measure the outside diameter of your charge-air piping before ordering.
FAQ
What size are these boots?
Each boot is 4 inches in diameter and 6 inches in length, designed for heavy-duty applications with 4" charge-air piping.
Will this kit fit my truck?
It fits any heavy-duty truck using 4" CAC connections. This includes many Peterbilt, Kenworth, and Freightliner configurations.
Are these boots stronger than OEM?
Yes. These 4-ply reinforced silicone boots offer significantly improved strength, heat resistance, and durability compared to many OEM rubber boots, especially on high-mileage or high-heat vehicles.
Do the clamps help prevent boost leaks?
Yes. The spring-loaded T-bolt clamps apply consistent tension and help maintain a secure seal under boost pressure, vibration, and temperature changes.
Do I need special tools to install the kit?
Only basic hand tools are required. Ensure your CAC pipes are clean and properly aligned before tightening the clamps.
Is this a direct replacement for my existing CAC boots?
Yes, as long as your system uses 4-inch diameter boots. This kit replaces most standard 4" charge-air boots used in Class-8 truck platforms.
