Our new super strong solid flexplate is an awesome value. Strong enough to stay together behind even the highest horsepower applications, these work great for hot street cars as well. These are the SAME EXACT FLEXPLATE as our aftermarket SFI 29.1 flexplate, however we DO NOT include the SFI sticker with these. We found that most of our customers were using these in street/strip applications and wanted the extra strength of these solid flexplates without having to pay extra for the "approval" sticker. So, now we also offer them at an EVEN LOWER price if you don't need the official "SFI approval" sticker. These includes all possible bolt patterns; Large with 5/16" bolts, small with 5/16" bolts, and 7/16" bolts for all aftermarket high performance and racing high stall converters. These are for internal (neutral) balance, they have no weights welded on them. This flexplate fits all standard 6 bolt crank flanges, and works for both big block AND small block applications!!
