MAHLE MOTORSPORT -2.5CC INVERTED POWERPAK PISTON KIT CHEVY LS7 4.000 STROKE 4.125 BORE Product Description:

Overview

The MAHLE Motorsports PowerPak kit is a high volume shelf stock program developed for high performance enthusiasts and sportsman class racers. The PowerPak pistons are predominantly made from 4032 alloy to allow for tighter cylinder to wall clearances and improved temperature stability. Each kit is complete with a set of high performance rings, containing either a low drag 1.0mm, 1.0mm, 2.0mm set, a 1.5mm, 1.5mm, 3.0mm set, or a 1/16", 1/16”, 3/16” high performance Ring Pak standard with big block kits.

PowerPak features include:

Made from 4032 alloy.
Forged pistons.
Fully-machined crown.
Grafal® anti-Friction coating on skirts.*
Phosphate-coated to reduce micro-welding and pin galling.**
Hand deburred.
High strength, light weight German steel pins.
Race-proven round wire locks.
Low drag ring pack.
Light weight slipper skirt forgings.

* MAHLE’s GRAFAL® skirt coating reduces drag, scuffing, friction and cylinder bore wear; reduces piston noise.

** Phosphate coating provides the grey appearance to the MAHLE piston. This dry lubricant coating (not to be confused with a thermal film coating) provides a lubricant film in the pin bores and ring grooves until the oiling system of the engine reaches operating pressure; particularly useful during the initial start-up or break-in of engines to protect against galling and microwelding. The piston crown is still machineable.

Designed for GM LS7 style V8 engines.
