So this is a thought I’ve had for a while- why hasn’t GM replaced the live axle on the Tahoe, Yukon, Suburban, Escalade with IRS like the Expedition by now? The one benefit of the live axle is better capability offroad, but the new GM SUV have such a long wheel base and an air damn hanging off the front bumper that’s only ~4 inches off the ground that you can’t seriously offroad them anyways. Are they just being lazy and saving the investment to switch the platform to IRS? I don’t know how everyone feels, but considering a loaded up Escalade can hit almost $100k, I’d expect for them to have switched to IRS by now.
