Progressive shocks and forks

Post by Mgrubbs1 » Sun Jul 02, 2017 7:52 am



Rebuilding an 83 GL1100 and looking to replace the entire air shock system and go to progressive shocks and forks.

Has anyone done this and what is the best brand?

I put Progressive 416's on my GL1100, and that was a tremendous upgrade, but those are also air shocks. They do however have a non-air version that has had good reports - a 410 or 412, if I recall correctly?

412 I have these on my 83 Interstate along with Progressive springs in the forks. When I drained the forks the oil was nothing more than a grey sludge....only 29K original miles...age is the killer...cleaned the fork lowers out with diesel fuel before i reassembled them. I ride solo without a heavy load of cargo and run the rears on the softest setting.

That would be the 412"s for the rear. Best upgrade I ever did. Did the front with progressive springs. There aint no way you can go wrong with progressive! The rear shocks are 5 position adjustable, and they also include the wrench. Forget the air assist- you wont need it. I surfed the net, and the best price I found for the 412 was $300 on e-bay. $100 for the front springs. Money well spent. Let us know what you decide on. Regards, Johnny

How well do they work with a passenger? We bottom out on every bump unless I over pressurized the stock shocks.

I have 416's on my 83 Aspencade (progressive springs in front) and 412's on my Interstate. I'll take the feel of the 412's over the air shocks in a heartbeat, much firmer than the air. Unfortunately, the Aspencade is the bike that the better half like to ride on, and she prefers the cushy air shocks. No matter, the Interstate is my daily rider!

Do you have any advice for the correct type of progressive spring set for the front forks on a '82 GL1100 Interstate that removes the nead for the air ride?
