I'm running the stock 4" pulley and i want something smaller for a little more boost. A 3.8 or 3.6 would be perfect. Let me know what you have and at what price. Thanks

 

Somebody has to have one laying around

if you change the jrsc pully you need to change the Idler Pulley i have one $10

 

I already have the upgraded crank pulley i need a smaller supercharger pulley, so no idler pulley needed, i already have both belts.

 

Alright just bought a 3.8 but i'd still like a 3.6 or 3.4, let me know if you have one

i got a 3.4 pully on my hatch the only problem is finding a belt to fit it right the smallest belt i found is a 23 inch round and i need a 20 inch

 

I'm not worried about the belt i have that covered, you want to sell that 3.4?

 

i bought my 3.4 pully from jrsc for $135 and that was too much. ebay hae some for cheep that were i should of went first...let me ask u a question were are you going to get the belt from ....cause i will need a belt that 20 inch round can you give a stock #

 

You can't buy pulleys for the older d-series JRSC, they don't make them anymore, especially the 3 rib pulleys. I want to know how your even using a 20 inch belt, that's the size of a regular alternator belt. Go to any parts store and ask them for a 20 inch 3 or 4 rib belt, whatever your uses. Finding short belts is cake, my belt is i believe 44 inches long.

got any extra 4 rib pulleys?
