ARP Photo Contest
Over the years, we’ve seen some amazing vehicles that use ARP fasteners. But, we can't get to every car show, track night or drive-in. If you've got a great motorcycle, ATV, jet ski or snow mobile, we want you to show us your ARP.
One entrant each month will win an exclusive ARP T-shirt. Each quarter, we will award a $200 gift certificate for ARP products.

ARP Ultra-Torque™
Fastener Assembly Lubricant
Today's critical fasteners - head studs and bolts, main studs and bolts, and driveline - have been designed stronger than ever before to handle the extreme loads. As a results, installation pre-loads - the amount the fastener is stretched during installation - are very high.
There are a lot of opinions out there about which fastener assembly lube to use and what the torque value should be. First, let's be clear: ARP provides torque specs for our fasteners based on using ARP Ultra-Torque. If you're not using our specs and our lube, you have no real idea what pre-load you're getting. We've done the testing where we can measure the torque applied and the resulting pre-loads. We've tested with our lube and the others people use...and we've got the results to back it up. (It's not like we're trying to sell more lube - we send you some free in every kit! We just want you're installation to be right.)
The slides below will show why you should use ARP Ultra-Torque:
