Hi!

I've been offered an underdrive lightweight pulley kit.

I already have a Perrin crank pulley mounted so wouldn't need the underdrive crank pulley.

Nevertheless could i use the power steering und the alternator pulleys of the underdrive kit?

Are these two pulleys stock size? Can i use my stock belts then?

Not sure if only the crank pulley is smaller and the other both are stock size - but it looks like.

Cheers,
Andy

 

Why not fit the whole kit and get the benefit of an underdriven pulley set. It may come with the right belts which will be shorter and if not you can easily swap belts for something a little smaller in circumfrence. Not a big problem and quite easy to do.

 

Thanks mate! I'd rather stick with the Perrin pulley. Do you know if i could use the stock belts when using the powersteering and alternator pulleys of an underdrive set?

 

Can anyone help?

Are the power steering and the alternator pulleys of an underdrive GFB set stock size?

 

Underdriven pulley kits have shorter circumfrence belts but you have quite a lot of adjustment on your pulleys in the first place as the alternator can travel through 2 or 3 inches. Getting the right belts is no big deal, just go to a motor factors such as Andrew Page.
