Hey guys. I recently took ownership of my dad's 2005 Avalanche Z71. It's at 199,000km, and runs great, aside from being a pig on gas. I just had to change all the brakes on it, have to fix a transfer case leak and rear main seal leak, but then other than rust under the paint, it'll be in great shape.
I'm looking to use this as a tow rig for highway use, and don't have much a need for any offroad ability. It's going to be pulling my racecar around.
What gets me about the truck is both the fuel economy, and the suspension feeling. It's definitely not optimized for cruising down the highway at speed, and I'm sure a lower setup would help with that. But what is there on the market that will work to lower it, as well as still be good for towing?
Also, how are these with O2 spacers should I want to make some test pipes to see if the cats are what's causing it to run at 16.5L/100 highway cruise (was around 9 when new). I'd rather not live with a check engine light until it's reflashed out, which I'm not looking to do immediately
