Parabolic Front Leaf Springs - Familar With These?
Parabolic Front Leaf Springs - Familar With These?
Is anybody here familiar with these taper leaf (parabolic) leaf springs? Mine OEM springs are shot. Ive read mixed results about skyjackers softride and the alcan (sp). The First Gen link seems to be about this Candian supplier. Leafs look rather thick.

The consensus seemed to be that, off the shelf, these parabolic springs are a bit too stiff. As Oliver stated, at least one thread involved an attempt to soften them. In another thread Jim Lane confirmed his success with some thin leaf springs from a California company called Atlas Suspension.
I have the 2" lift ones. They are stiffer. 
My goal is to re-work the shackle angle (dead vertical right now) to achieve more suspension movement for the minimal spring flexing.
Plan B is to add more weight up front (battery, bumper, winch).
Plan C is to replace the lower leaf with a factory overload (also a tapered/parabolic type leaf).

I've been considering them for a while but decided that I'll try polyurethane spring tip inserts in between a stock 6 leaf setup that isn't sagged right out.
Jim Lane did it to his rear spring pack and said it really helped the ride. As far as I know no one has tried them in the front with the original springs.

Merry Christmas to you!

Truck rides nice, not like a new truck, but nice for me. Much better than the stock springs were.
BTW... The spring inserts eventually will fail, as they're being crushed over time. Been a couple years now, and they're thinner than they were. Oh well..... live and learn..
Way back in the early days, like earlier than 1950, some if not most leaf spring packs were packed in grease and wrapped in burlap and sheet metal to retain the grease.
I have the spring tip inserts in the front of my 92. Granted the springs are beefed up, larger main spring, added another leaf, 2.5" rise in height, new bushings.....

Would you recommend taking the time to put inserts in the front and rear for the improvement in the ride you gained? I was thinking of adding a leaf or 2 as well to gain an inch or so.








I bet worn out leaf springs were never heard of back then
