Overview

The Howards Cams ProMax 2618 Forged Race Pistons are designed for ultimate performance in Chevrolet Small Block V8 engines. These pistons are forged from 2618-T61 billet bar stock, a material chosen for its superior strength and ability to maintain shape under extreme pressure and high RPMs, unlike higher-silicon content pistons that can become brittle. The ProMax pistons feature CNC-turned skirts for proper operation under intense heat and severe side loads, reducing the risk of scuffing or splitting cylinder walls.

Standard features across the ProMax line include forced pin oilers, accumulator grooves for improved ring seal, and lock removal indents. Each set comes with lightweight .150" wall, heat-treated aircraft quality wrist pins and double spirolox for secure locking. These pistons are intended for a 4.040" bore with a 3.480" stroke and 5.700" connecting rod, resulting in a 357ci engine displacement.

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.
