ATK High Performance Engines: Engine Parts & Accessories Built Better Than New
When it comes to sourcing engine parts and accessories from a brand with genuine engineering depth, ATK High Performance Engines stands apart from the crowd. With a lineage stretching back to 1936 and a dedicated High Performance Division launched in 2007, ATK brings decades of accumulated powertrain knowledge to every component it produces.
A Philosophy Rooted in Reverse Engineering
One of ATK's defining characteristics is its use of reverse engineering. Rather than simply replicating original factory designs, ATK analyzes OEM engines to identify known weaknesses and potential failure points — and then addresses those areas through upgraded components, improved machining practices, and tighter quality control. This means that when you select an ATK engine part or accessory, you're not just getting a replacement — you're getting a component that has been deliberately improved upon.
Quality Standards That Set the Bar
With over 70 years of building experience and having achieved ISO/TS 16949 quality certification — the highest level offered — ATK was prepared to launch its High Performance Division with serious credibility behind it. Today, ATK operates one of the finest high performance engine shops in the country, featuring state-of-the-art dyno equipment, climate-controlled clean rooms, and a fully trained staff capable of building any high performance engine combination.
ATK was also the first to offer a "new car" style warranty — an exclusive 24-month/unlimited mile warranty on every engine. That same commitment to standing behind their products carries through to their parts and accessories lineup.
Built for Every Performance Level
ATK offers its GM, Ford, and Chrysler performance engines and components in three stages to help enthusiasts achieve their specific performance goals. Whether you're sourcing parts for a street build, a classic restoration, or a dedicated track application, ATK's engine parts and accessories are engineered to complement the brand's proven crate engine lineup.
ATK specializes in building custom, stroker, crate, and turn-key performance engines — and their supporting parts and accessories are developed with those same builds in mind. Every component is chosen to work in concert with ATK's broader engineering philosophy: eliminate factory shortcomings and deliver reliable, repeatable power.
