Good morning Brian: Just got back on here to check things out - I'm sorry but the snubber is sold pending the payment - the other person was just ahead of you, but if the deal falls thru I'll get back to you - but to answer your question the lowest adjustment would be 4 3/4" - the highest 5 3/4" - I wasn't able to use this on my 70 Duster in it's present form - I had to lower the unit by 1" to make it work - I had a welder friend cut out a section of the tower and then cut off the same amount on the threaded snubber itself - it worked - just another pain in the butt when modifing cars - Thanks David
