well i have been wanting some for a while and i finally went and bought them. here are the pics from the install that took all of 30 minutes.
this is what came in the box: two timbrens, two mounting brackets, and two bolts.
this is the timbrens attached to the brackets
as you can tell there is a great difference compared to the stock bump stops and the timbrens.
this is the timbrens installed on the truck... the only thing that i found about them so far is that they picked the rear of the truck up a few inches and made it ride ruffer... i think they just need to break in a little.. if there is someone else out there that has them some input on how they do unloaded would be appreciated..
