Enough to upgrade 1 axle.

Follow directions to a T, specifically torque settings, use appropriate loc-tite. Drive around, re-inspect torque. Had to tighten one time, since then these have not budge. Going on over a year now.
Use: PSC Hydro Assist w/37s.

Timely upgrade for me; while removing my knuckle studs I found that five of them wiggled a bit (even though I torque regularly), two were stretched a little, and one had a slight bend. With my new hydro assist upgrade these bolts were going to fail or break the knuckle. New studs installed, lock tighted, and torqued. Personally it does wonders for my piece of mind.
