Today's critical head studs and bolts, main studs and bolts, and driveline have been designed stronger than ever before to handle the extreme loads. As a result, 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 their fasteners based on using ARP Ultra-Torque. If you're not using ARP specs and ARP lube, you have no real idea what pre-load you're getting. ARP has done the testing where they can measure the torque applied and the resulting pre-loads. They've tested with ARP lube and the lube others use... and ARP has the results to back it up.

Consistent and fair shipping value!

Sensational! I was almost giving up importing to my country due to the absurd prices of shipping .. but in this shop I found the value of coherent freight and I was able to import a Weldon filter and some ARP accessories .. STMTUNED is to be congratulated and I hope to make other purchases in the future!

Thank you for the incredible feedback, Elisson! We appreciate your business : )
