IPD - Caterpillar 3406B Enhanced Durability IPD Steel Piston Inframe Kit - KIF9314/62/CS

Forge the Future: IPD Steel Piston Kit – Truckers' Durability Dynamo for CAT 3406B Engine Endurance

BPS Diesel is an official stocking distributor for IPD, with the 3406B inframe kit in stock and ready for free shipping within the lower 48 states—no extra hidden charges. This IDP 3406B inframe kit is a durability upgrade from aluminum 3412 industrial off-highway articulated piston (9Y4004 or 3780509, 1979314 crown) to steel with approximately the same 14.5:1 compression ratio as the original standard aluminum OE piston. The IPD piston is articulated with the same CR, ensuring seamless integration while enhancing strength for extreme conditions. It includes the 1979322CSWS cylinder liner with crevice seal design to help prevent scuffing, making it ideal for converting and boosting longevity in demanding trucking environments. Note: Upgrade to piston cooling nozzle #1663650 with #1118606 bolts (3/8"-16 thread) or #2773076 nozzle with #1515925 bolts (7/16"-14 thread); change to higher-pressure oil pump #0R9449 (replaces #0R9448) or #10R0428 (replaces #0R9697), or increase relief pressure with #9Y1792 retainer replacing #9Y1800. This performance inframe kit includes pistons, skirts, crowns, thrust plates, main bearings, gaskets, retainers, pins, rod bearings, liners, and ring sets—everything needed for a thorough rebuild that minimizes downtime and maximizes uptime on rugged hauls.

Key Features

• Steel Articulated Pistons (14.5:1 CR): Upgraded from aluminum for superior durability, maintaining original compression ratio while resisting wear in off-highway heavy-haul applications.
• Crevice Seal Liners: 1979322CSWS design prevents scuffing, ensuring smoother operation and extended life under high-stress conditions.
• Main Bearings (STD Diesel): Seven bearings provide robust support, reducing friction for reliable performance during intense trucking demands.
• Rod Bearings (STD Grooved): Six bearings engineered for strength, minimizing failures in high-vibration environments.
• Thrust Plates: Two plates enhance axial stability, promoting overall engine balance and efficiency on long routes.
• Upper Gasket Set: Comprehensive seals for leak-free rebuilds, with optional oil pan gasket (+$149) as reusable per Caterpillar guidelines.
• Piston Components: Includes skirts (1630930), crowns (1979314), pins (8N1608), retainers (7E5665), and ring sets (3400RS5) for a complete, ready-to-install solution.
