Piston Assembly Kit (April 01, 2009)

The release of Mahle Motorsport’s Oldsmobile PowerPak piston assembly kit offers 4.155 and 4.185 bore sizes for a 4.500 stroke. These drop-in performance-built pistons give a 10.1 to 1 compression ratio. Each PowerPak includes forged pistons, round wire locks, high quality steel wrist pins, and three low drag, racing rings (1/16″, 1/16″, 3/16″). Precision CNC finish machined pin bores for reduced piston to pin clearance, phosphate dry film lubricant and Mahle’s Grafal anti-friction coatings ensure consistent, durable performance. High quality steel pins (145 grams), radiused valve pockets and forced pin oiling come standard with the PowerPak.
