The Rhino Ramps do work with a lowered truck. No draging, plenty of clearence. Makes work under the truck very easy. Wish I would have bought them sooner.

 

I bought them too but my garage floor is to slick for them to work... they keep moving while I am trying to pull up on them... the rubber deal on the bottom doesn't help.

 

FWIW, I gave away all my metal/plastic ramps and built my own with 2X10's from Home Depot. Much more stable and dirt cheap. Just ask the guy at the saw to cut them down with a 45 degree angle to make it easier to drive up on.

 

To keep your ramps from sliding get one of those throw rugs, that the wife has decided no longer matches the decore, and put it under the ramps. If that does not work got to Wally World and get a kitchen rug that has rubber backing.

No more slipping!!!

 

Love mine!
