I'm looking for something on my Armada for more tire clearance. Anyone ever use this? Looks like a good idea to me, but thought I'd see if anyone has one first hand experience.

Thanks.

never used it but it looks sweet!

I know I saw one on a vehicle at RESO, but can't remember which one.

i got one on my crew cab probably the one you seen. it works great so far. ABS makes very good products we use them all the time.

if you dont mind me askin TCB, how much you pay for that bad boy? i looked at the link and all i saw was around $1,200.
