I am trying to come up with some information on all the lower pulleys. Knowing that the tuners make the pulleys in different sizes and they put a # on them (IE- lbs over stock). I would like to have a measurement of all the pulleys that are out in production. I just measured my JLP 8# pulley and was 9.5". Please measure the pulley at the top of the grooves and not the side edge. Thanks for your help.

 

ASP pullies:

4# ... 8.47"
6# ... 9.00"
8# ... 10.00"

 

Thanks for the info, anyone know the size of JDM's 8# pulley or JLP's 10#?

 

Well my JLP 5# lower is very close to 8.5"

 

Is there a more complete list of pulley sizes?

 

this has been done in the past a couple times maybe you can find the missing info in the search...

 

easter,

here are some lower pulley diameters I found from a search:


2# = 7.90"
3# = 8.17"
4# = 8.50"
5# = 8.75"
6# = 9.00"

I have a supposed 2lb and 6lb lower. The measurements are 7.36" on the 2lber and 8.9" on the 6lber. Those measurements are from the top of the grooves. I'm wondering about the 2lber because the stock is supposed to be 7.5"...???

 

Just remembered that one of our members over a year ago put a spreadsheet together that goes over blower RPMs and stuff.. It has sizes on it

I'd like to see a new version showing all the Lower pulley brands that are available. Seems there is a difference (ASP/PSP/Metco seem to be on the smaller side vs. JDM & JLP) Be nice to see a break down of them.

JDM 2,4,6,8
JLP 2,3,4,5,6,8,10
Metco (same as LFP) 2,4,6
ASP (same as PSP) 2,4,6

My old ASP 2# & 4# were smaller than friends JDM 2#& 4#

Seen a JLP 5# that was same size as a Metco 6#
