Air bag spacers

I just ordered the firestone ride rite kit. I've got 1.5 inch shackles on the back. Anyone know if I need spacers for it?

 

Are they coachbuilder shackles? He can tell you if you need a spacer either way.

 

They're the Toytec shackles. I'd talked to coach awhile ago and he had said I would need them with 1.75 lift. I'm thinking about dropping it down to 1". With the bags I won't have to worry about the tear end sagging under a load.

 

I run a 2" coachbuilder spacer with 3.5" lift in the rear (dakar leaf spring and 1" coachbuilder shackles), pics below. I'd say install the airbags, then see how it looks. Lower it after you install if its not looking good. Daystar also makes a shallower spacer (http://daystarweb.com/videothumbnails/AirBagCradle.jpg)

 

Yeah, I was thinking about putting them on to see what it looks like. What am I looking for? The bag making good contact without having to pump them way up?

 

I had the Toytec shackles with Firestone airbags. I ran them for a few months without a spacer and they were fine. When I had the truck on the lift at work I realized the rear axle would droop to the point of over extending and possibly damaging the bags. I eventually installed the Daystar cradles.

 

Thanks Chris, I'll just get the cradles. Got a smokin deal on the kit, what's a couple more bucks.

 

Yeah, I had a 71 f250 back in the day. That thing was a beast, I used it to haul firewood. It could handle 3000 lbs easy with stock springs.

 

Just purchased a new 30-ft camp trailer! Sag's a bit! Have a 6-in suspension lift, just ordered Firestone Ride-Rite air suspension kit! What size spacers do I need under the bags?
