My ride improved dramatically after I changed my shocks to KYB Monomax. I simply took the old shocks off which were twin tubes then I upgraded to a monotube and man did that changed my ride on my 2000 Escalade, the shock I used was KYB Monomax a monotube shock absorber.
This is the same process to change the front shocks for the following models: Chevy suburban, Chevy Tahoe, GMC Yukon XL, GMC Yukon
If you do any type of towing or you haul heavy loads you might want to upgrade to a monotube shock absorber. My SUV seems to glide down the street now. I was using a twin tube shock Excel G, based on how the monotube has made my SUV handle there’s a good chance I would never go back to twin tube.
