Help!!! I own a 1936 half tn pickup that I have restored and it's been so long I can't remember how the overload springs mount; Do they mount under the leaf springs or on top? Are they secured with the leaf spring U bolts or have a separate set? Anyone have any diagrams or ideas. Thanks so much for your help. olgzer

Olgzr,

You've got me there! My original equipment '36 pickup has no overload springs to my knowledge...just the 8-leaf springs it was born with. Here's a photo of the right rear. Are the overloads just extra leaves?

Overloads usually go on top of the main springs with longer u-bolts, however I did not see overloads listed in my parts book for that model. Only as posted above an 8 leaf spring so perhaps it was a local add on. Also they should be in a position to contact a frame bracket. That should give some indication of where they mount.

There is a cast iron part that sets on top of the axle held in place by the extra long "U" bolts that hold the bottom leaf springs on. The overload springs are attached to the cast iron part on top of the axle by shorter "U" bolts. The overload springs rub (when in use) against rubber bumpers pads that are attached on the frame. These are at point of contact near end of spring area. I can send you an email attachment showing how mine are mounted.

I'm sure Olgzr would appreciate that-his email is listed on his profile.

hi there,
overload springs weather aftermarket or OEM are mounted on the top of the original spring so that the additional load is taken up gradually and distributed to the vehicle spring. I have a series on land-rover and many fit overload springs to gain extra loading capacity, that is how I know.....

I have sent you pictures via email of the ones on my '36 truck. The rub pads are riveted to the frame.
