My truck is in the shop now getting swapped out from the 7.5 RCX to the BDS 6. The angles weren't ideal and it rode pretty rough. I didn't do enough initial research so ended up wasting money on this kit. I don't think its a horrible kit since I didn't have any mechanical issues in the few hundred miles I drove it, I just think it has its place on a truck that stays on the pavement and doesn't ride in areas that have potholes. Check out my other posts and the one in "post your angles" thread to see the angles and issues I was dealing with. With that said, I feel that there is a lot of misinformation from people on this website. People are on the bandwagon and bash RC when they haven't even had one of their kits on their vehicle. They make it seem that if you put an RC lift on your vehicle its going to fall apart tomorrow. The fact of the matter is, it will run but will slowly wear your front end and will need to replace ball joints and CVs more frequently. Further, the kit is made from second line steel. While doing the install a few parts broke, including the the top of one strut when tightening and another part that I cant remember at the moment which leads me to believe that they are not near as strong enough as they should be. I don't want to say too much as I haven't seen my truck yet with the BDS but will post once i pick it up next week. One thing I've learned especially with lifts and such is that you literally get what you pay for. If you're like me want safety, ride quality, performance, and peace of mind I wouldn't put this kit on your truck. If you just want lift and don't really care then I wouldn't worry about it. Sorry for the ramble but just my 2 cents here.
Also the RC 7.5 and BDS 6 are both stretched lift kits which will cause the suspension to be different than factory. However, the RC angles are worse. Fabtech will give you a full drop but uses a strut spacer unless you get coil overs and doesn't give enough front ground clearance in my opinion. Honestly, I have read a lot about Mcgaughys and hundreds of pictures and the CV angles are good at 7 but going to 9 will be extremely similar to the RC lift and the thing that steered me away was the angle that the upper ball joint was on the Mcgaughys. It was identical to the RC angle. If you do decide to stick with the kit, make sure you check your welds and ball joints, etc. frequently. Its really just a matter of safety in my opinion.
And finally, I could not seem to get the stabilitrack to work properly with the kit. The angles of the knuckles seem to be causing the issue. I am confident the BDS kit will fix this.
I find it funny that the dude just asked a simple question and we are all telling him to swap the kit :lol:. But in all seriousness, I hope this helps in your decisions as I wish it helped me.
