So I know you could get a 2500 Burb with Quadrasteer and a 6.0 liter, I've seen them and driven them. But was the Quadrasteer option available along with the 8.1 big block?
You could get a 2500 Suburban / YukonXL with either Quadrasteer, or an 8.1L big block, but NOT both. You had to choose.
The Quadrasteer rear steering axle uses a Dana 60 with Dana's friction disc "Trac Lok" limited slip. That particular limited slip arrangement has an input torque limit that the 8.1L engine exceeds.
