Suspension for towing
I finally got my '21 Tahoe set up to tow out 5000# Apex Nano camper. This Tahoe doesn't have the factory air bags, it does have ZLG trailering package. The factory hitch is limited to 10% of the tow capacity (see the sticker on the hitch) so 790# tongue weight is all you get on that load point...- 301Bobbo

21+ IRS SAG issues when towing product design (looking for someone in Michigan)
Agree. Without Max Tow package ($5K) or factory air shocks why even have an 8400# tow rating. The hitch has a sticker says only 840# allowed.- 301Bobbo

Suspension for towing
When you go to order and update with make and model those bags are removed. IRS won't allow aftermarket bags or jounce springs. Bilstein 5100s seem to be the only option and a WDH- 301Bobbo

2021 Denali (Yukon XL) Transmission cooler standard?
Without the max tow option you will have a significant sag at the hitch (2"+) a smaller radiator and no trans cooler. Another option is the ZLG and the air shocks options. If you tow a 5000# trailer with a WDH you will likely not be limited by payload (see B post info) or tow weight but may be...- 301Bobbo

Bilstein 5100 Review
5100s 24-3177474 have been BOd for a while but are now ordered for my '21 RWD. The IRS coil over damper suspension is quite problematic to solve the 3" sag when towing the camper. No sumo springs, bump stop, or air bags are made for this or newer model years. WDH can only take out 1" so I'm...- 301Bobbo

Tow package / Max tow package ________ Brake controller????
My '21 Tahoe LT has Advanced tow package (ZLG) that has an integrated electric brake controller. Works quite well on our 25' Apex Nano camper. If ordering, get the Max Tow package bc the ZLG has no way to take out the 2+" of rear sag when you put 650+ on the hitch ball. My WDH only takes it up...- 301Bobbo

I'll get a pic up soon. The '21s and newer now have independent rear which precludes air bag or jounce lifts like on a live axle.- 301Bobbo

New here looking at ordering a 2023 Yukon Denali
Got a '21 Tahoe and due to the new independent rear, no air bags or Sumo springs can be installed. Maybe this.- 301Bobbo

RV Towing
My wife wanted a bigger camper so we bought the '21 Tahoe 5.3 because the '19 Canyon diesel made my life miserable towing. Too much trailer push for that short wheel base. New camper is 25', 5100# loaded (Apex Nano), 680# on the tongue. With hardly anything in the SUV (payload), the Tahoe rear...- 301Bobbo

Cylinder deactivation for the 2021-2023's?
If you have tow/haul I don't think it'll deactivate cyls in that mode. But that's hardly a fix.- 301Bobbo
