Progressive spring part number?

blue05twin · July 05, 2006, 08:19:43 AM

Got a quick question for your suspension guru's out there. I have read several post about the progressive springs and I have noticed that two different part numbers are mentioned / used. So which one is correct?

111128

OR

111138
?
Maybe the 28's are for 2002 and younger while the 38's are for 04's and up?

My 1998 model took the 28's.

Noone knows the difference? Wow I'm shocked

Progressive doesn't even seem to know.

In their Product Search application, the GS500 does not appear in the MODEL list for any year after 2002.

Believe it or not, the prgress web site mentions a heavy duty model of the springs for riders over 200lbs. But I couldnt find much info on them.

I believe the pre 04 bikes were 11-1128.

You're right, but I think you mean the "pre '04" bikes.

Hmmm my 28's just came in Fedex today. . . will install them anyway. If I don't like them or they don't work can always give them to a GS member and order the 38's. Didn't realize that the front forks were different on +04's.

I don't think they are. I used RaceTech springs for an '01-'03 GS and they worked just fine.

I forget. I think I found it through the board, but now this 111128 number is coming up, so I dunno which is which.

Thats the number found on the site when I did a search yesterday. As I mentioned above, they said something about HD springs for the gs but dont list a part number for them.
If they were available, Im sure they would probably have a spring rate close to the sonics or racetech springs.
Ay, I said "close", Alpha
