IPD - Caterpillar 3406E/C15 Single Piece Steel Piston Upgrade kit - KIFSPC15W/02/CS

As an official stocking distributor for IPD, BPS Diesel offers the premium Caterpillar 3406E/C15 Single Piece Steel Piston Upgrade Kit (KIFSPC15W/02/CS)—a robust inframe overhaul solution designed to enhance durability and performance in non-ACERT applications. 

This upgrade transitions your engine from the original 2-piece articulated pistons (1807352) to advanced 1-piece IPDSteel® welded pistons, maintaining the same 16.6:1 compression ratio while providing superior strength, heat resistance, and longevity under extreme loads and conditions. Featuring crevice seal liners with a 0.001” oversized ID to prevent scuffing and ensure smoother operation, this kit minimizes downtime, reduces wear, and extends service life for heavy-haul trucking, construction, and industrial operations. Engineered with a shorter piston pin to accommodate the 1-piece design, it requires no additional modifications. Ideal for operators seeking reliable, high-value aftermarket upgrades without warranty implications.
