Product Details

ARP 200-2903 Pro Series Flexplate Bolt Kit

These high performance bolts are forged from an aerospace alloy and heat-treated before machining and thread rolling. These bolts have a larger-than-stock shank diameter for improved flywheel register and are rated at 190000 psi.

Flexplate bolts play an important role in the performance and safety of race cars and street machines alike. That's why the fastener experts at ARP developed special bolts that are far superior to OEM hardware. Originally developed for NASCAR Winston Cup competition, this Pro Series Flexplate bolt kit is forged from aerospace alloy, rated at 200,000 psi, and heat-treated prior to thread rolling and machining. It features an exclusive, flat, 12-point head design and larger than stock shank diameter for increased strength and improved register.

  • Complete with washers and nuts where applicable
  • .500 under head length, and thread size is 7/16-20
  • Rated at 200,000 PSI, which is considerably stronger than Grade 8 hardware
  • Forged from aerospace alloy and heat-treated prior to thread rolling and machining
  • Far superior to OEM flexplate bolts

So far so good. Disappointment in shipping...

Easy to use the page, and navigate. Good description of part and vehicle, fast check out.

Was good and fast



Parts were actually in-stock unlike every other retailer I tried. Quick shipping too.

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Recent purchased new Hawk HPS brakes for my 2010 Hyundai Genesis Coupe 3.8 Track.<br><br>The order was processed quickly, packaged very well, and was the correct items I had ordered. <br><br>Not only did I experiece great customer service and quick shipping/processing, Autoplicity also had the LOWEST price of any vendors for these parts I could find online.<br><br>Great service + Great pricing = Match made in heaven!

The best price I could find and it arrived in 2 days! I'll be doing business again.

Had problems using the search tool so I called direct. They helped locate Air Lift shocks I needed and told me that I.E. browser is sometimes a problem. They were helpful and my items got shipped the next business day.

Amazing prices
