My truck sits too high - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**425HP409** · 02-16-2018, 01:46 PM

When I restored my truck, i replaced the rear springs because they had sagged and the center coils were sitting on each other. It now sits too high, like an original truck with the original type overload springs that I installed. Does anyone make lowering springs, or can I install air bags in the original spring perches? Or should I get the torch out and "lower" the springs?

Here is Summits listing on some of what you can get. About a 3" spring would get you sitting level.

Stock GM that were like the original overload ones. They had wide coils at the top and bottom and narrow coils in the middle.

Don't use a torch, use a cut off wheel. You could cut one coil off and see where it puts you. Free to try out.

Negative. I wouldn't cut the rear springs. You lose the pigtail when you do that and then have no way to retain the spring. Now the fronts on the other hand, you can always hack a coil off of those!

and they make a virtual bolt in rear air bag kit for trailing arm rear ends .

I was more interested in who made the springs and maybe a part number. Some of the aftermarket springs they list as heavy duty are for use in a suburban. They have a higher spring rate and will sit really tall in a truck. This may be the issue you have. You may want to try just a set of standard truck springs and see how that works.
