Mahle Motorsport has launched an all-new GM LSX Combo that is meant for high output, and naturally aspirated power adder applications. The new product is the outcome of the company’s focus on innovation, versatility and cost-conscious budgets. Mahle says that the new PowerPak kit offers high strength with the incorporation of an all-forged 2618 aluminum alloy piston to facilitate increased detonation resistance and a combination valve pocket design. This design will cover LS1, LS3 and LS7 cylinder heads.
In case the valve pocket layout is unknown when assembling the short block, these pistons have the capability to accommodate an LS1 style cathedral port, LS3 style rectangle port and also LS7 style cylinder heads. The new Combo PowerPak Piston Kit does not restrict users into a single configuration with listings for flat tops, dishes and domes. Hence, changes can be made as needed.
Compression ratios are available from 10:1 through 14:1 while the bore options can range from 4.000-inch to 4.185-inch. The kit also includes an HV385 coated steel oil ring set: 1.0mm top, napier 1.0mm 2nd and 2.0mm.
The PowerPak pistons can be used by aspiring racers and professional racers. They are all dual-coated with a phosphate coating that accounts for the characteristic gray appearance of the piston. The phosphate coating is a dry lubricant that provides a lubricant film protection in the pin bores and ring grooves. Each slipper skirt has also been treated with Grafal, Mahle’s proprietary coating which can minimize wear, drag, scuffing, friction and piston noise.
