Re: Rear suspension question

It’s an overload spring. It only touches under a heavy load and helps bear the weight.

Re: Rear suspension question

Thank you my initial thought was they were something like that. Now that i know what they are called. I quick Google search gave me some great info. Helper springs seems to be another common name for them.

Re: Rear suspension question

Usually helper springs are an add on for leaf springs. The overload leaf on your truck is a GM factory option for the coil spring rear.

Re: Rear suspension question

It is a 12 bolt. But main has nothing to do with the rear axle. Enjoy your truck as it sounds like you are!

Re: Rear suspension question

Unless you’re using your truck to cart heavy loads on a regular basis you could probably remove them. They weigh a fair bit and are relatively easy take off or replace if you need.
My truck leads an easy life now so I took mine off.

Re: Rear suspension question

Pop the cover off your differential to see if you have a 12-bolt posi, and drop the oil pan to see if you have a 4-bolt main motor...Enjoy your classic ride!
