Default Rear leaf spring

I need a new leaf spring since the one on the car has started to crack.

What type and from where do you recommend me buying?

Any other upgrades I should do at the same time?

Thanks guys.

I'd check with Mirrock for a used one.

GM tested these springs for millions of cycles. I think they wore the machine out twice, the spring was fine.

Hyperco probably made the originals, have had one on the back for many years. I believe they are available through Vette Brakes. You will have to paint it black.

I found a pair of originals, both front and rear, so it worked out in the end.
