Hell and Back Overhaul Kit — 1LW/2WS/6NZ

The famous 6NZ kit: Hack Nation's Hell and Back coated overhaul kit for Cat 1LW, 2WS and 6NZ.

A Hell and Back coated Hack Nation overhaul kit for the Cat 3406E and C15, with the gasket kit packed right on top.

What makes it better

• Hell and Back coated rod and main bearings. Hack Nation's bearing coating holds a film of oil on the bearing surface, protecting the bottom end on dry and cold starts and helping it survive oil starvation or fuel dilution.
• Ceramic-coated piston crowns. The coating reflects combustion heat back into the power stroke instead of into the piston, for better efficiency.
• Superfinished, mirror-finish wrist pins. About Ra 1.5–2.0 against roughly 6–8 on a factory pin, for less friction and wear.
• Aviation gasket paste included. Packed with every Hack Nation Cat kit, with instructions, for the metal-to-metal gasket joints.
• Gasket kit packed with it. The overhaul gaskets ship in the same package.

Why it matters

• Independently verified. An independent diesel shop tore down and measured a Hack Nation Cat 3406/C15 overhaul kit on video: coated two-piece piston, superfinished wrist pin, and liners and gaskets all in spec.
• Built for trucks that work hard and sit between jobs. Coated bearings matter most on dry starts, which is where bottom ends get hurt.
• Proven coating. In Hack Nation's 7,300-mile loaded-bulker test on Texas hills, its piston coating stayed on 100% while a competitor's came off completely.
