SFI Flexplate for 5.7/6.1/6.2/6.4L Gen 3 HEMI with NAG1, 8HP70, 8HP90, 8HP95 915663 By ATI

If your flexplate is flexing harder than your gym selfies but still can’t handle the heat of your HEMI, it might be time for an upgrade. Enter the ATI Flexplate: forged from custom-drawn SFI-spec chromoly steel and tougher than your buddy’s opinions at the drag strip.

This beast is SFI 29.1 Certified, which is basically the high-performance version of winning student of the month—except instead of showing up early to math class, it shows up ready to handle serious RPM and high torque abuse without flinching. ATI double MIG/TIG welds each plate because single welds are for quitters (and because strength and precision actually matter).

Each flexplate is built directly from OEM drawings to make sure it fits like your favorite pair of stretchy pants—snug, reliable, and no surprises. It’s quality inspected to exceed flatness and run-out tolerances, meaning it stays truer than most dating profiles. And just to get a little extra nerdy, it’s precision balanced on Hines digital equipment down to 0.10 oz-in resolution. If that doesn’t impress you, pretend it does so the engineers feel better.

Compatible with most high-powered HEMI setups running NAG1 and ZF transmissions, including 8HP70, 8HP90, and 8HP95 AWD. Works on the mean machines like Challenger, Charger, Durango 392, Trackhawk, Grand Cherokee SRT8, and Ram TRX (unless it’s one of those maybe not scenarios listed below—sorry Jeep 5.7 friends).

Note:
🚫 May not fit 5.7L Grand Cherokee
🚫 May not work on RAM with 8-speed
🚫 Not for V6 engines (they know what they did)
🚫 Does not fit RFE transmissions

But hey—if your ride qualifies, bolt this bad boy on (longer bolts included!) and enjoy smooth, consistent passes.
