Mahle PowerPak Pistons

Mahle PowerPak pistons are forged pistons with steel pins and wire locks. The pistons are hand-deburred and then coated with dry phosphate to protect against ring micro-welding and pin galling during initial startup. For additional performance, Mahle added its proprietary Grafal anti-friction coating to the piston skirts. Part numbers with T on the end have a cutting edge ceramic-based thermic barrier. The barrier is resistant to thermal shock, insulates the piston crown, and reduces heat transfer to increase performance. These replacement pistons are available in a wide variety of size options for fitment with specific engines and pistons.

CP Pistons MX Piston Kits

CP Piston MX piston kits are available for 4-stroke powersports applications. They are fully boxed-style pistons with a skirt coating. The wrist pin has a Diamond-Like Coating (DLC) that is harder then steel, ensuring durability unsurpassed by any other pin on the market today! These kits include the piston, wrist pin, locks, and rings. CP Pistons use X-forgings to minimize friction and weight without compromising strength. Double pin oilers add twice the amount of oil from the cylinder wall to the wrist pin. Radiused domes are use to maximize quench, while eliminating possible hot spots that promote detonation. The MX piston kits have a V-shaped groove machined into the second ring to collect excess blowby between the top and second ring. This groove is known as the accumulator groove.

Total Seal TSS Street Piston Rings

You won't lose horsepower due to blowby when you install Total Seal TSS Steet piston rings. The secret is in Total Seal's gapless second ring technology. This arrangement uses an oversize cast iron main ring, plus a chrome-faced secondary ring that overlaps the main ring's end gap. This interlocking design forms a gapless seal, which gives Total Seal TSS Steet rings a miniscule leakdown rate of just 2 percent or less, compared to the 8 to 10 percent rate for conventional gapped rings. They're perfect for street or mild race applications with 10.5:1 or lower compression ratios.
