A friend of mine wants the ASP UD Crank Pulley for his 3.1 Camaro.Is it possible to reuse the stock belt?? Those belts are an extra $40 and his is basically new (Month Old) Could the tensioner give up the extra slack so that the stock belt can use a underdrive crank pulley?

 

No it wont he will have to get a new one.

 

if u go to aspracing.com they will give u the part number for the new belt u will need
