For me they rubbed like crazy and wouldn't work.
First picture is with them at stock height.
Second is with a 2 inch blocks and a 1.75 inch t-bar crank.
You judge for yourself. Just keep in mind, each one of these trucks came off the production line at slightly different heights, so no one experience is atypical. That is why they worked for one guy, but not for the other guy.
Personally I spent around $100 for the two inch lift since it was just 2 inch blocks and a t-bar crank. It was a small investment considering my tires alone ran me $1,000 and $600 for the rims.
Just my .02 cents.
