Buying Guide

Need a strong flexplate? These parts handle lots of power. Let’s find you the perfect SFI plate.

Users love how SFI plates boost performance. They also feel safer with a strong, reliable part. Now, explore the best options to find the perfect fit for your build.

Here’s what to think about when you buy:

  • Engine Compatibility: The flexplate must fit your engine. Check it works with your engine type and year. Pick a flexplate that fits right.

  • SFI Certification: SFI certification means the part is safe. It can handle high speeds and power. Always choose an SFI-rated flexplate.

  • Material Strength: Look for flexplates made from hard stuff. Chromoly steel and billet steel are great choices. These materials last longer.

  • Balance Type: Know if your engine is internally or externally balanced. The flexplate must match this. An unbalance part hurts your engine.

  • Tooth Count: Make sure the tooth count matches your setup. Common counts are 153, 164, and 168. The wrong count means trouble with your starter.

  • Thickness: A thicker flexplate is often stronger. Check if it’s thicker than the old one. This handles power better.

  • Welding Quality: Good welding makes the flexplate stronger. Look for double-welded rings and MIG/TIG welding. Strong welds mean it lasts longer.
