I would suggest you ask Progressive that question for a better answer, Their customer service is 1-877-690-7411 Ride safe.

 

1. do you have the maximum load for the standard Shock 422? me and my wife and my bag 350 pounds Max !! 5-6 ride in the summer

 

I lowered my Heritage about a year ago so the OL could ride it. She still wasn’t comfortable on it and it rides like a freight train. As soon as I get the electrical problem fixed on it, it’s going back to stock height.

 

After riding my Deluxe lowered for a season, I saved up some cash and went with the shotgun shock air ride. Night and day from the lowering kits. It rides like a Cadillac.
Best upgrade I have done to the bike....

 

 

Another opinion here;
I ran mine lwr'd for about a year. Looked cool !!
Worse thing I ever did!!!!
I made the mistake of putting the Harley lowering fork
springs in it. Those are junk !! I ran the extenders on the rear shocks for awhile,
then I changed to the 422's.

It rode like a brick. The first time I bottomed the frame out on the ground
(Just going around a street corner) and made the rear wheel skip . . . I
put it back to stock height (as soon as I wasn't seeing stars anymore)

My wife's 03 has the HD Lwr'g kit frt & rr. It rides like a bucket of monkey nuts too.
