IPD CAT C15 ACERT Inframe Kit Low Compression 16:1 3466615 MXS, NXS, BXS, SDP

IPD Caterpillar C15 ACERT Low Compression Conversion Kit — 16:1 CR 3466615 

Applies to ESN Prefixes: MXS / NXS / BXS / SDP

Engineered by IPD — a globally recognized leader in Caterpillar aftermarket components, this premium Low Compression Conversion Kit is designed to convert C15 ACERT engines from the original 18:1 compression ratio to a more durable 16:1 configuration.

Lowering the compression ratio significantly reduces peak cylinder pressures and internal stress — a critical advantage for high-mileage engines operating under heavy loads. The result is improved durability, reduced risk of catastrophic failure, lower operating temperatures, and enhanced long-term reliability in severe duty applications.

This kit is most commonly used when converting a Twin Turbo ACERT (Compound Turbo) engine back to a Single Turbo configuration, making it the preferred solution for fleets and rebuilders seeking simplicity, reliability, and reduced maintenance costs.

At the core of the kit are IPD’s heavy-duty One-Piece Steel Pistons, engineered to withstand extreme combustion forces while delivering superior strength, stability, and longevity compared to traditional multi-piece piston designs.
