Atomic Steel Main Girdle – EF–AU Ford SOHC 6-Cyl | 10mm Thick | Bottom-End Strength Upgrade
Description:
When you start pushing big power through a Ford SOHC 6-cylinder EF–AU engine, bottom-end integrity becomes critical. Flex, cap walk, and crank movement under load can destroy bearings and ruin your build — unless it's properly reinforced.
The Atomic 10mm Steel Main Girdle ties the entire lower end together to significantly improve crankshaft stability and block rigidity under boost and RPM. Laser-cut from 10mm steel plate, this girdle is engineered to eliminate main cap movement, reduce crank flex, and deliver confidence when you're chasing serious horsepower.
✅ Key Features:
✅ Suits Ford EF–AU SOHC 4.0L 6-cylinder engines
✅ 10mm thick precision steel plate – laser-cut for strength and accuracy
✅ Dramatically reduces main cap walk and block flex under load
✅ Increases bottom-end rigidity for boosted and high-RPM engines
✅ Ideal for high-horsepower street builds, drag cars, and track use
✅ Trusted in Atomic-built SOHC engines making 600–1000+hp
✅ Compatible with factory and aftermarket fasteners (clearance check recommended)
