i think you will be fine.. goto oreilys and have them order a 65/66/67 inch belt...

then go in the next day and play with them all.. the tightest one is the one to use...

With the 2.7 and Metco idler and limiter removed, I'm maxed out with the 66" right now. It is nice and tight. Adding a 2lb lower, I just wonder if an extra inch (67") will be enough?????

did you do the tensioner mod??

grind the hell outta the stop...

and you should be able to run the same belt...

its only 3 bolts... maybe 4 for the tensioner to come off...

also helps with belt slip...

ight i have an 02
i put the 2.73 upper on it and stock underdrive.
with stock idlers
what size gater back do i need or whats the part number i want it to b tight ya know no slip

DallasGT01 · 12-04-2007, 04:18 PM

with the tensioner mod i would run a 65" belt

4080650 should be the part number...

if not

K080650 is a gates belt...

you will have belt slip either way...

thats a small *** pulley without some idlers or a NON Slip pulley

03 H/D with 6 lb LFP lower kit, stock SC pulley and adding a single 90mm Idler LFP kit. which belt should I use. closest setup on the chart would be a 69.5 belt what do you guys think ??

PLEASE MAIL ME

6lb lower/3.25 upper/METCO idler pulley kit with 90mm pulley-70"

3.25 is stock upper for us idler kits are pretty close to all the same except for the MP.....

IF your tensioner tab has not been removed then most likely a 70, might be possible to get a 69.5 on her though....

Hit up GreyHD I am pretty sure he is running the same setup you will be and can confirm

myfast5oh · 12-29-2007, 10:17 AM

Tab has been removed Thanx.

bgstew6 · 12-29-2007, 10:28 AM

with the tab removed and a metco/lfp idler you might even be able to get a 68.5 on her....knocking that tab off really gives for alot of extra compression to get belts on.

I've got stock HD upper, 6lb lower, metco old style idler(w/o the hole in the center), 100mm lfp idler pulley. Which gatorback belt do I need to get?

i would say with the tensioner mod you could run a 69 or maybe a 68" belt

K080690
K080680

4080690
4080680

add 1-2 inches...

its not hard to to... you just grind the stops off to allow the tensioner to go farther...

joedpl · 03-13-2008, 10:15 AM

so do you think a 4080700 will work? I really don't want to do the tensioner (SP?) mod.

bgstew6 · 03-13-2008, 01:16 PM

I guessing 70 or 70.5
