Every MAHLE Motorsports piston is backed by 90+ years of racing heritage and technology. From the invention of the first aluminum piston to the most advanced design and machining processes being used today, MAHLE delivers unmatched performance and durability. MAHLE’s light-weight, low-drag, design specific forgings are machined with close attention given to ring groove quality, tolerances and consistency. All MAHLE Motorsports pistons are dual or triple coated, adding protection and maintaining consistent performance over the life of the engine. There is no secret why top professional race teams use MAHLE Motorsports pistons.

Nothing supports the MAHLE Group's technology leadership as strongly as our achievements supplying the motorsports/racing industry including Formula 1 seasons with 16 out of 18 race wins supporting six of the ten teams, nearly two decades of straight wins at Le Mans, championships in all three top levels of NASCAR® and he majority engine supplier to the Indy Car Series.

However, product development for race engines results in more than just sporting achievements. It is often the top technology used by MAHLE in today's motorsports products that end up in tomorrow's production automotive models. Transversely, MAHLE’s involvement in a wide array of OE production programs that include extensive R&D testing covering many aspects other than peak power and strength can provide technology from a different point of view that can be incorporated into motorsports products. A 24hr Grand Prix race is a severe test stand as you can imagine as is an industrial engine producing 1500+ cylinder pressures 24 hours a day 7 days a week for months on end. In providing products that succeed in any environment, allows MAHLE to master the everyday requirements from public roads to the most grueling motorsports competitions.

Power Pak pistons
The MAHLE Motorsports Power Pak kit is our high volume shelf stock program developed for high performance enthusiasts and sportsman class racers. The Power Pak pistons are predominately made from 4032 aluminum alloy to allow for tighter cylinder to wall clearances, and improved temperature stability. Some applications require 2618 alloy including the Power Pak Plus category. Each kit is complete with a set of high performance rings, containing a low drag 1.5mm, 1.5mm, 3.0mm set or 1/16’, 1/16”, 3/16” high performance Ring Pak standard with big block kits.

Power Pak feature includes:
- Forged piston for performance applications
- Fully-machined crown
- Grafal anti-Friction coating on skirts*
- Phosphate-coated to reduce micro-welding and pin galling**
- Pin bores binished on CNC boring equipment
- Deburred
- High strength, light weight steel pins
- Race proven round wire locks
- Low drag ring pak
- Light weight slipper kirt forgings


ProSeries pistons
The MAHLE ProSeries piston was developed to meet the demanding needs of professional racers. The set is race-ready and designed for—asphalt and dirt circle track racing as well as drag racing. MAHLE Motorsports gives you a competitive edge with pistons that are meticulously finish prepared right out of the box. MAHLE machines the correct valve reliefs, dome profiles, and ring grooves for upper level competition.
The pins are CNC machined with proper clearances, and every piston is hand deburred. Plus, with factory applied phosphate and GRAFAL® skirt coatings, you eliminate the expense and uncertainty of aftermarket coatings.

ProSeries features includes:
- Race proven quality pistons forged from 2618 aluminum alloy (the 2 barrel pistons are made form 4032)
- Ring grooves machined for light-weight low-drag racing ring packs
- Asymmetrical valve pockets
- Lateral gas ports for improved sealing, generating improved horsepower
- Precision milling for additional weight savings
- GRAFAL® anti-friction coating on skirts*
- Phosphate-coated to reduce micro-welding and pin galling**


* 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.
