Upgrade Your Haul: IPD Steel Piston Kit – Truckers' Durability Dynamo for CAT Engine Endurance

BPS Diesel is an official stocking distributor for IPD, ensuring you get top-tier parts like the 3406E inframe kit in stock and ready for immediate shipment with free shipping within the lower 48 states—no extra hidden charges. This IPD 3406E/C15 inframe kit is a C15 durability upgrade for non-Acert off-highway applications, transitioning from articulated (1807352) to 1-piece steel pistons with a 16.6:1 compression ratio matching the original. It includes the 1599778CSWS cylinder liner (0.001” oversized ID) to help prevent scuffing, delivering enhanced strength and longevity for engines facing extreme loads and conditions. The kit contains six pistons with pins/rings, six liners with crevice seal design, seven main bearings, six rod bearings, one thrust bearing, and one upper gasket set (note: IPD does not include the oil pan gasket as per Caterpillar guidelines deeming it reusable; add it for an extra $149 if needed). Ideal for heavy-haul operators, this upgrade minimizes downtime, boosts efficiency, and extends service life in rugged terrains where reliability is non-negotiable.

Key Features

• 1-Piece Steel Pistons with Pins/Rings: Upgraded from original articulated design (16.6:1 compression ratio) for superior durability and performance under high-stress trucking demands.
• Crevice Seal Liners (0.001” Oversized ID): Specially designed to prevent scuffing, ensuring smoother operation and longer life in non-Acert off-highway applications.
• Main Bearings (STD): Seven high-quality bearings provide robust support and reduce friction for reliable engine rotation during heavy hauls.
• Rod Bearings (STD): Six bearings engineered for strength, minimizing wear in high-vibration environments common to diesel rigs.
• Thrust Bearing (STD): Essential for axial load management, enhancing overall engine stability and efficiency on demanding routes.
• Upper Gasket Set: Comprehensive seals for a leak-free rebuild, promoting optimal compression and performance without including reusable oil pan gasket (optional add-on for $149).
