Hell and Back Elite In-Frame Kit — X15 CM2350 (CPL 4343)

Hack Nation's Hell and Back Elite Series in-frame kit for the Cummins X15, CM2350 (CPL 4343).

The X15 version of the Elite Series in-frame kit: rebuild a CM2350 X15 in the truck with the coated, upgraded parts already in the box.

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.
• Coating about 1 mil thick. Factory bearing clearances are unchanged, so the kit assembles like OEM.
• 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.
• Elite Series. Hack Nation's premium coated kit line, a step above its standard kits.

Why it matters

• Built for trucks that work hard and sit between jobs. Coated bearings matter most on dry starts, which is where bottom ends get hurt.
• More than a standard kit. Hack Nation's standard kits share the same core parts; the Elite Series adds the coated bearings, coated piston crowns and superfinished wrist pins.
• 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.
