Hey guys what underdrive pullies do you recommend?

Also where to get them and the part number thanks!

4.8 v8 05 silverado

Looking for a crank and alt pulley so i dont lose power just doing the crank by itself. thanks!

 

Powerbond under drive pulley. Scoggin Dickey has them for $199.99 & includes what appears to be an ARP bolt & both belts. The ALT pulley is separate, about $30

 

Who r what is scoggin dickey? Thats a good price

 

I recommend the stock ones

 

Srsly? Look to the right of your screen & you'll see a box that says SDPC. I got my UDP from them. I bought the ALT pulley from Summit. You can tell Scoggin Dickey that you want a specific part # for the belt. The belt part #s/lengths can be found on Thunder Racing.com's website. The A/C belt is a certain size, the serpentine belt length depends on whether you are running the ALT pulley or not. I think without the ALT pulley, I ran 14.2 volts, once I changed the ALT pulley, it went back up to 14.4 volts.

 

Need a tool to press the new pulley on? Don't risk using the stock bolt to press it on and possibly ruining the threads of your crank.

 

Anyone have any photos of the install? Does it look stupid with the 2 belts?

 

Ur truck already has 2 belts. will look the same.

 

i bought mine off summit, trick flow udp with alt for 200$ but it did not come with a belt
