Mahle PowerPak Plus Piston and Ring Kit (930276047T) Engineered for the discerning enthusiast, the Mahle PowerPak Plus piston and ring kit epitomizes precision and performance, tailored specifically for the Chrysler, Dodge, Jeep, and Ram Mopar Hemi Gen III 5.7L engines from 2003 to 2021. Crafted from high-grade 2618 forged aluminum, these pistons are not merely components; they are a testament to Mahle's commitment to automotive excellence, designed to withstand the rigors of high-performance applications while enhancing overall engine efficiency. Design & Engineering Every aspect of the 930276047T kit has been meticulously engineered to optimize performance. The inclusion of a thermal barrier coating effectively manages heat, ensuring longevity and reliability under extreme conditions. The lightweight design, featuring low-drag slipper skirts, reduces unsprung mass, contributing to improved handling dynamics and throttle response. Each piston is precision CNC-machined, with ultra-flat ring grooves and pin bores that maintain tight tolerances, ensuring seamless integration and performance consistency.

Backed by the full Mahle manufacturer warranty. JAP is an authorized dealer — your warranty is valid from day one.

FULL MANUFACTURER WARRANTY

Every part ships new in the box with the manufacturer's standard warranty — terms and duration vary by brand (typically 1 year to limited lifetime on hard parts). We only sell through authorized channels, so coverage is never voided by gray-market sourcing.

Defects in materials and workmanship are covered. Trail damage, improper installation, modification, and normal wear items (bushings, pads, wear plates) generally are not — that's standard across every brand we carry.

SEPARATE FROM RETURNS

Warranty claims (defects after use) and returns (unused parts within 30 days) are different lanes. Not sure which applies? Message us first — we'll route it the fast way.
