Z55 coil spring options

[LeakySeals]

My Escalade has a broken rear coil spring. It has the Z55 auto-leveling suspension. The rear air shocks and compressor have been replaced recently so I'd like to keep it rather than do a conversion. But they don't sell the Z55 coil springs anymore. Just conversion springs which are different. wondering if anyone has advice and if there is any information about z55 springs. Like what the height is relaxed and with weight and how much weight does spring support I can't find anything OEM just aftermarket info. Any information would be helpful thank you

I would look into GM part # 15182556 or 15182558 . It's the rear coil spring for the Tahoe/Yukon with Z55 suspension. They share the same shocks so the spring has to be close. In fact, some places online list 15182556 as compatible with the Escalade Z55. If those part numbers are discontinued, I apologize, as multiple online sources said they were still available.
