Just installed my new ADD Pro front bumper....Some thoughts...
1) there is a shutter box that needs to be completely removed, but instructions were somewhat vague..
2) After removing the shutter box, there is a rubber sealing piece across the top where the stock bumper was...No instructions on what to do with that...We left it in place and drilled holes in the lower grille shell to zip-ty the rubber piece AND the small wire harness that runs right across the IC space...(see photo 2 sorry bad lighting) and left it to fit under the bumpers main tube...
3) The bumpers lower section where the new skid plate is bolted to is to bolt back up to the same x-member as factory, HOWEVER..the new bumper piece is flat and the secondary skid plate has ribs embossed on it, and simply bolting on the new portion on top of the embossed plate would just "squish" it flat...we added several flat washers to take up the small gap on the rib so we could tighten it up without flattening the secondary skid plate...
4) All the hardware fit just fine, as did the bumper and ADD did a great job bending the main tube to fit the contours of the front of these trucks...real tight and correct...Very happy with fit and finish...and looks better in person then the photos...
Took just under 2 hrs and we spent extra time making sure the harness wasn't going to fall down later...Oh yeah...ADD gives you an ass load of very HD brackets to bolt on just about any light system...
