Pro Tru Street pistons kits, each .............................................................from $655.99 DSS Racing Forged Pistons DSS Racing forged pistons come in multiple bore diameters, styles, and compression ratios—call us or visit SummitRacing.com to find yours. Made in the USA. SX Series Pistons These pistons are forged from high- silicon, low-expansion 4032 aluminum alloy with fully CNC-machined crowns, heavy-duty piston pins with precision-finished pin bores, dual True Arc locks, oil drainback windows, side reliefs, and diamond-turned skirts. They also have generous valve reliefs that accommodate performance head and cam combinations, forced pin oiling, and drilled bottom-land intercepting oil grooves. It all adds up to a piston capable of handling increased compression and moderate levels of boost or nitrous, all at an affordable price. SX Series pistons, set ............................................................................ from $559.95 FX Series Forged Pistons These pistons are built to handle high rpm, boost, and nitrous injection. They feature patented X Groove skirts for improved cylinder and ring life, plus thinner ring grooves with optimized ring lands for incredible strength. Other features include precision-honed forced-oil pin bores with heavy-duty pins, additional CNC milling in non-critical areas, plus drilled bottom ring lands intersecting oil groove drain backs, deep CNC-machined valve pockets, and more. Choose from 4032 high-silicon low- expansion alloy, 2618 high-strength low-silicon alloy, or 2618 alloy with XR extreme duty wrist pins and horizontal gas porting for 1,500-plus horsepower capability!

SRP Street/Strip Pistons These CNC-machined street/strip pistons from SRP are some of the highest-quality aluminum slugs you can get at a price that’ll leave you with money to burn. They’re made from low-expansion 4032 forged aluminum alloy that’s lighter and 50% stronger than comparable cast aluminum pistons. They feature forced pin oiling and oversized valve reliefs, plus CNC-machined ring grooves, skirts, and pin bores for drop-in performance right out of the box. All pistons work with press- fit or floating pins, and use 1/16" top, 1/16" secondary, and 3/16" oil control rings (sold separately). Multiple compression ratios available (actual ratio dependent on cylinder head volume and deck height). Sold in sets of 8 with Spirolox and wrist pins included. Applications available for Chevy, Ford, and Mopar engines—call us or visit SummitRacing.com for Made in the USA status, more details, and to get yours. SRP street/strip pistons, set of 8 ............................................................from $624.99 Speed-Pro Hypereutectic Pistons Ideal for performance street, street/strip, and even mild forced induction applications, Speed-Pro hypereutectic pistons have high-end features— without the high price. They’re cast from 16.5% silicon FM425 alloy for high tensile strength, excellent scuff resistance, and minimal material growth. That means you can run tighter bore clearances for less noise, improved cylinder sealing, and more power. Plus, they’re treated to an exclusive DUROSHIELD® moly-graphite skirt coating that reduces friction and prevents damage from inadequate start-up lubrication.
