Caterpillar C15 ACERT Inframe Overhaul Kit — MXS, NXS, BXS, (18:1 compression ratio piston)

Product Description

Restore the power, efficiency, and long-term reliability of your Caterpillar C15 ACERT engine (MXS, BXS, NXS serial prefixes) with this premium Interstate-McBee Complete Overhaul Kit, engineered with the correct 18:1 compression ratio to match original factory specifications.

Unlike a standard inframe kit, this FULL OVERHAUL solution is designed for a more comprehensive engine rebuild, replacing a broader range of critical internal components to return your engine to near-new operating condition.

This kit restores lost horsepower, improves fuel economy, reduces oil consumption, and significantly extends engine service life — helping you avoid premature failures and repeated repairs while minimizing costly downtime.

Manufactured to meet or exceed OEM standards, these heavy-duty components deliver the durability required for commercial trucking, construction, agricultural, and industrial applications where reliability is mission-critical.
