Title: Mounting hard bags over rear shock springs
Post by Oldfeller on 12/23/16 at 12:42:43

I am mounting a set of hard mounted bags over my rear shock springs on my Barcalounger. I expect to see some "loaded bag deflection" when going over bumps and I am seeking some actual knowledge of folks who have done this sort of situation before.

How far out from the springs should I space the bags ??? Opinions ??

I seem to swing from no offset (let it rest lightly against the springs for constant alignment support) to 1/4" to 3/8" to only allow occasional contact during bumps.

Are you mounting hard or soft saddle bags?

For soft saddle bags, I would leave a 3/8" to 1/2" gap.

For hard saddle bags, you need to make sure that the shocks will not come into contact with the bags when compressed.
I found out the hard way and the shock was starting to wear a spot in the left saddle bag from it rubbing on compression. Mind you, they were cheap Mutazu plastic saddle bags.

They are "semi-hard" bags made up of fake leather viewing exterior with a polyethylene hard "inside toward the springs" wear surface.

I foresee a 3/8" offset naturally deflecting over time to partial constant engagement.

If I set it up at a continuous light contact I fear having it turn quickly in the direction of simple wear through.

I guess I am thinking once I see some attempted wear through I would drop in a 1/8"thick sheet aluminum wear surface that could be renewed as needed.

Your point about spring squat making the spring diameter grow is a good one .....

Hay ?

What about some "Gliding" Material between the Bag and Shock ? Maybe fastened (zip-tied) to the top of the shock ?

;)

Ditto that. They should not be allowed to contact the shock at any time. I did the same thing to my Mutazu bags, and some throw over bags.
If possible, you need to put a "dummy bag" where the real bags will be going, then take it out and bounce the bejeeze out of it so you see where it will touch the shock.
