Hey guys, on June 1st I ordered a 4x2 black monotone Longhorn with cattle tan interior and 392 rear. On train now with july 7 arrival date. Super excited, especially since reading all these forums. taking to Speed and Truck world right away for a 2' level kit, westin bull bar, 325/60r18 terra grapplers with 970 series moto blk/machine rims and flat blk bush wacker fender flares. I have a mobile personal training company here in Miami so I basically go to peoples homes all day and work out of my truck bed, I have about 300lb of equipment in truck bed year round,,,do you guys think that will make the back sag?? should I add a 1" block to the back to accompany the 2" level kit??
