Just thought I'd share with you the size difference between a 13lb & 10lb lower. Installed the 13lb today with the help of STL01SVT I will be getting dyno tuned on Aug. 26th.

It was really hard driving home and not getting on it.

 

Glad to see you didn't scrape that pulley on a speed bump on the way home.

 

What is the diameter of those pulleys? All 10lber's are not created equal...

 

13lb= 11in
10= 10 1/4in

 

TRU....

 

Geee look at that.

 

Thanks Goose...I wish we in the Lightning world got into the habit of listing the lower pulley diameters like the uppers... Especially the vendors!!!
