Oh, please. If you do the suspension work to the Chebbie to get it to do what the Raptor does, its tow rating will be far below its stock rating, just like the Raptor's tow rating is far below the FX4's. There are trade-offs to everything.
LOL Have you ever built an offroad truck?
You do realize a Raptor is nothing but an F150 with a 6.2, some better A arms and Fox shocks. Plus 4.10 gears and selectable lockers.... Pretty simple stuff and can be done to most any truck fairly cheep.
The rest is just looks and bells and whistles, adds nothing to prefirmance.
The New 1/2 ton 6.2 GM has a tow rating of 12k lbs. So even if it lost a little, it would still stay well over the 6000 mark set by the Raptor.
