ARP 2442901 Pro Series Flexplate Bolt Kit for Gen III/LS Series Small Block Chevrolet

ARP 2442901 Pro Series Flexplate Bolt Kit for Gen III/LS Series Small Block Chevrolet

Q: I'm doing a 4l80 swap in my silverado 1500 which had a 4l60, are these bolts the correct length to go through my flex plate and it's spacer?

I used these in a tci flexplate conversion for th350/th400 also using converter spacer and they worked perfectly

Q: will these fit the LSA crankshaft and flexplate without a spacer?

The LSA crankshaft is an 8 bolt so you'll need to buy 2 sets and it fit on my LSA in my 09 CTS v with no issues

Q: Are these bolts a replacement or upgrade to gm performance flexplate bolt gm ls-series part number 19257940?

They are both! They replace factory LS flexplate bolts. I have a turbo 6.0 LS and it will destroy factory bolts on a good launch and these arp bolts have been in about a year and have not let me down yet

Q: Will these fit a 2006 gmc sierra 1500 with the 5.3? I only have 3 bolts

These bolts goes from the flex plate to the crank.The three bolts goes from the flex plate to the torque convertor if these 3 you need,you may try this number ARP 230-7304.Hope this helps.Good luck.
