Remove overload springs with drop?

I guess I wasn't previously too well versed on the suspension options of these trucks. I am to the point of reassembling my (coil) rear suspension with the CPP adjustable track bar, shock relocator kit, and 3" drop coils. On top of that I had to build new mounts for the differential, and I made them about 1.5" taller to give a bit extra drop as I had the springs in before the restoration and the rear wasn't quite low enough (The CPP 3" coils sat higher than the cheapo 3" coils I took out).

So anyway, today I am working on getting everything together and notice there are significant clearance issues with the overload spring pad and the track bar mount for the passenger side trailing arm. So that got me wondering, took a look at my parts truck and it hasn't got overload springs.....I guess they were an optional part? I could clearance the pad to make it work, but I have to wonder if there is much point in keeping the overload springs in a non-hauling application? Chopping them at this point would suck seeing as the frame is painted, but I guess it really isn't a big deal either.

Re: Remove overload springs with drop?

I'd remove every part associated with them. No need for the extra clutter and weight.

Re: Remove overload springs with drop?

My bottomed out on the slightest little bump with them with a 2/4 drop, so, they need to go.

Re: Remove overload springs with drop?

I would see if you can make them work. One day you'll be loaded with something, be it a load of kids in a parade or a bunch of something or another you need moved NOW... and you'll wish you had them. It's not like they weigh 150 pounds or somethinhg.

You always have a lot of good input and your Quotes are cool, too.

Re: Remove overload springs with drop?

with 4 inch springs and 2 harlys in the back, your axle was on the frame most likely (I would suspect that even with a C notch.) I have 3 inch (if memory serves) drop coils on the back of my burb and it would slam the axle into the frame just from stomping on the throttle before I put the helper bags in the coils.

It is unlikely I'll have a need to haul, the tailgate is shaved and I will have a hard box cover. However, I'm glad you support keeping them. It won't take much work to keep them, and I figured worst case scenario I wear out the rubber bumpers often.

Its not as simple as just keeping them, if they are the kind I had. Mine bottomed out so hard that it almost bounced off the seat if I hit a bridge or big bump in the road. Mine was the big single overload spring that bolted on the rear of the frame. If I was going to be towing with lowered truck, I'd go with air bag helpers. I really saw no reason to keep the helper springs.
