2 years ago i did 2/4 drop on my 2016 Yukon Denali with NorcalSS kit and kit come from Beltech part # 753. I still have OEM autoride shocks. Did everything by instructions. From day 1 rear end was hard. Now its getting worse. Its bouncing much more. Denali have 70k and about 10k on drop kit. I know my autoride shocks are still good no leaks and and airbags still holding pressure. I also did free travel mod and installed DJM swaybar links and also swapped Beltech rear shock extenders for DJM units. That helped with clunk noise since pinion angle was wrong with Beltech unit. But bounce/hard rear end is still there

Did anyone else have this issue ??

I would be curious about this also... my '17 Yukon Denali with 60K miles when I bought it rides the same.... bouncy .... like the rear shocks are frozen.
My truck is 100% with the factory 22" rim option which isn't helping with a smooth ride.

What size rims/tires are you on?

Im gonna play with adjusting rod on the rear. It may ride on springs only. Adjusting rod from 2.6" to 2.8" may help. But its too damn cold outside. -17 in Missouri

You may not think the magneride shocks are shot…but I bet they are! Ride quality went bad fairly quickly when they were going out…to almost totally freezing up…mine didn’t leak and held air…nothing visibly indicated they were worn out but they absolutely were….replaced mine with passive Arnott’s and ride was improved immediately!

It's more than likely the Magna ride rear shocks. They can go bad and not show any psychical signs. the best way to tell is to take the shock loose at the rear mount remove the air line and try to compress it by hand. You should be able to compress it with moderate pressure. If you can't than you have your answer bad shock.

Thanks

Making rod 0.100 longer helped a little. Im gonna order new aluminum M5 turnbuckle rods from McMaste-Carr and cut them to my length
