Caterpillar 3406E, C15 One Piece Piston Conversion Inframe Kit, IPD Brand

This IPD Inframe Kit is designed specifically to replace Caterpillar number 1807352 (16.6:1 Compression Ratio) pistons. These pistons included a shorter wrist pin than the factory piston uses. That difference to accommodate the thickness of the high density bronze bushing provided with our pistons. This inframe kit also includes .001" oversize ID liners to help prevent piston scuffing in high load applications.
This one piece conversion kit will work for any Caterpillar 3406E engine with 1LW, 2WS, 5EK & 6TS serial prefixes.
Since the installation of these parts requires custom tuning and was designed for high horsepower applications, there is no warranty offered. 
Inframe Kit Includes (6) Upgraded, Crevice Seal Cylinder Kits (Welded Steel Piston with pin & locks, Piston Rings, "Crevice Seal" Cylinder Liner, Liner Seals) (6) Rod Bearings (1) Main Bearing Set (1) Inframe Gasket Set* (Please see note below regarding Oil Pan Gasket)
*Please Note: Some Caterpillar engines use an "Isolation Seal" for the underframe stiffener plate. (Manufacturer Part number 1685248) This item is not included with our kits, as Caterpillar suggests reusing this gasket up to 3 times before replacement. Please inspect your isolation seal. If you require a replacement, it will need to be ordered separately.
If you require a complete lower gasket set with crank seals and are unsure which part number to order, please give us a call with your Engine Serial Number and we'd be happy to assist.
