Overview

The DSS Racing D.S.S. FX-Series Forged Piston and Ring Kits are designed for high-performance engine builds. These kits feature forged aluminum pistons with a 4.030-inch bore and a -10.00cc dish volume, suitable for stock stroke applications. The pistons are constructed from a premium aircraft quality 2618 alloy and include a DSS XP piston ring set with gas nitrided steel top rings.

The FX Series pistons incorporate a patented X Groove skirt design to reduce skirt, cylinder, and ring wear from fuel wash down and debris. They also feature forced pin oiling, drilled bottom land oil groove drain backs, precision honed pin bores, and high-strength wrist pins. These pistons are engineered for naturally aspirated, nitrous, or boosted engines, offering a balance of strength, power, and longevity.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
