Are there any options for the frontend on a 07 suburban other than a strut spacer. I am not looking for anything extreme just something with enough clearence for 33's. Are any of the parts for the newer silverados compatable?
I installed an Icon coilover providing 2" of lift on my 2007 Yukon running 285/70/17 Nittos. It's a little more "sporty" on the street and works well off-road for the long rollers. In the chop it's worse because the suspension tops out quickly. I've been considering the BMS upper arm but haven't pulled the trigger because it would give me a reason to take a vehicle off-road that really has no business going off-road.
The Bilstein adjustable spring seat strut rides decent but as with any spacer / coilover / strut replacement that provides lift you end up reducing the amount of rebound travel at ride height and this doesn't make for a very smooth ride off-road or on crap SoCal roadways. The BMS upper arm and a coilover / strut designed to provide additional rebound travel is the hot setup if you want minimal lift and good on and off-road performance. Nothing wrong with the spacers either, just make sure it's a 1-piece dealio that doesn't increase the preload on the springs.
