Description

The Trick Flow GenX 280 HD cylinder head is engineered for GM LS3 engines, offering enhanced performance capabilities. This head features a 4.000-inch minimum bore diameter and is constructed from durable aluminum. The CNC-machined ports, with 280cc intake runners and 87cc exhaust runners, are designed for optimal airflow. Key specifications include a 67cc combustion chamber volume, 2.165-inch intake valves, and 1.600-inch exhaust valves. The head is designed to support a maximum valve lift of 0.650 inches and includes valve springs. It also comes with new rocker arm rail mounts, specifically for use with LS3 1.7 ratio rocker arms, and features a 6-bolt pattern for secure mounting. Designed for performance applications, these cylinder heads are suitable for GM LS3 and LSX engines. They are compatible with engine sizes ranging from 6.0L/364ci to 6.2L/376ci and potentially up to 7.0L/427ci. The product is sold as a pair.

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.
