Mahle LSX Combo PowerPak Piston and Ring Kits

Mahle Motorsports offers GM LSX Combo PowerPak piston and ring kits, designed for high-output, naturally aspirated, power-adder applications. These Combo PowerPak kits offer the best of strength in an all-forged 2618 aluminum alloy piston to allow for increased detonation resistance, and a combination valve pocket design that will cover LS1, LS3 and LS7 cylinder heads.

Features and benefits of these LSX Combo kits include:

* PowerPak pistons are all dual-coated with Phosphate coating to provide the piston’s characteristic gray appearance (dry lubricant provides a lubricant film protection in the pin bores and ring grooves)
* Each slipper skirt is treated with Grafal; Mahle’s proprietary coating to reduce wear, drag, scuffing, friction, and piston noise
* If the valve pocket layout is unknown when assembling the short block, these pistons will accommodate an LS1-style cathedral port, LS3-style rectangle port, and also LS7-style cylinder heads
* With listings for flat tops, dishes, and domes, these Combo PowerPak piston kits will not lock you into a single configuration, allowing for changes that can be made, as needed
* Compression ratios are available from 10:1 and cruise all the way up to 14:1 with bore options ranging from 4.000 in. to 4.185 in.
