ARP Ultra Torque Assembly Lube (.5 to 20 oz.)
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 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.
ARP Ultra-Torque Fastener Assembly Lubricant gets you within 5% of the required pre-load on the first pull and stays consistent with each subsequent cycle-race prep, machining, pre-assembly and final assembly. Premium grade moly base with rust and corrosion inhibitors.
Effective lubrication range -30° to 550°F, with a load range of 500,000 psi.
- Eliminates preload scatter
- Remains consistent on every cycle
- Resists fastener loosening
- Saves Time - no need to re-torque 6+ times
- Maintains consistent clamping force
- An absolute "must" for any serious engine builder
