Gear Up Your Rig: IPD 16:1 Overhaul Kit – Truckers' Twin-to-Single Turbo Transformer for CAT C15 Conquest

BPS Diesel is an official stocking distributor for IPD, with the Caterpillar C15 IPD Low Compression (16:1) Conversion Inframe Rebuild kit in stock and ready for free shipping within the lower 48 states—no extra hidden charges. This kit is for converting a C15 ACERT 18:1 compression ratio to 16:1, recommended for taking a twin turbo C15 and converting it back to a single turbo engine in BXS, MXS, NXS applications. It features IPD's special steel welded piston (3466615, 16:1 CR) and includes the 1599778CSWS cylinder liner (0.001” oversized ID) to help prevent scuffing, ensuring enhanced durability and efficiency for off-highway use. The 6-cylinder kit is complete with pistons, liners, rings, retainers & seals, upper gasket set, rod bearing kit, main bearing kit, and thrust washers (IPD does not include the oil pan gasket as per Caterpillar guidelines deeming it reusable; add it for an additional $149 if needed). Perfect for heavy-haul operators facing rugged terrains, this upgrade minimizes downtime, boosts torque, and extends engine life without the failures of high-compression setups.
