This part is super easy to maintain with only the loosen of a nut and turn of a knob (can be done while engine is running) while only needing attention every 500-750 miles depending how heavy your foot is on the gas pedal!

 The tensioner body and turning knob are made from 6061 billet aluminum. The internals are made from 17-4 stainless steel.

Stainless steel ARP bolts are included.
