The Caterpillar C15 ACERT Rebuild Kit includes high quality components that meet or exceed the specifications set by the OEM. All rebuild kits are manufactured and assembled in an ISO 9001:2015 certified facility. That alone solidifies the commitment to you, the customer, that you're getting quality parts that will keep your Caterpillar C15 ACERT running for another million miles. 

This rebuild kit includes a complete upper gasket set. This means you're getting everything you need to pull the head off and put it back on again. 

Injector o-rings and your turbo installation set are also included.

High-performance, forged-steel monotherm pistons are also included in this kit. They have lower compression and higher horsepower, making them ideal for higher performance Caterpillar engines. 

Your piston pins are hardened and tempered for improved strength and wear resistance. 

Six ring set, including the heavy haul top ring, six liners, and liner seals are also included.

A complete lower-end bearing kit is included. The rod and main bearings are constructed with a Tri-Metal material for longer wear. 

Lastly, this inframe rebuild kit comes with a pan gasket set. When you're trying to completely reseal your engine, don't forget to replace the pan isolator gasket also. 

Again, this kit will meet or exceed OEM standards, so you  don't have to sacrifice quality to get the best price possible! Buying aftermarket parts can save you 30-50% off OEM pricing. And, this kit comes with a two-year parts and labor warranty.


So, if you're looking to upgrade your C15 ACERT's performance, then this is the kit for you!
