Available in Basic, Basic with a new bearing (not installed), or with new stock black pulley and bearing (installed) or with an aluminum pulley and new bearing installed.

         .    We've been asked about these units and, obviously, people want to know how they work. As they used to say - Ask the man who owns one! We have endless reports from racers, dune buggy people and street performance types who have told us in no uncertain terms that they have never had a belt tension device perform as flawlessly as these idlers.

               Whether you just drive hard on the street all the way up to serious competitive racing these units are unsurpassed! Sold exclusively by Corvair Underground's GoVair division since 2000.  As written up in Seth Emerson's latest revision of How To Hotrod Corvair Engines.   The runs always sell out - Run number 10 has been out of stock since last July -
