So I use my 09 NNBS rcsb as strictly a work truck. I own Valley Lawn Care, so there is always either a trailer, snowplow, or construction materials hanging off this truck. I started by purchasing the "Zone Offroad" brand add-a-leaf kit and the "Fat Bob's Garage" brand strut spacer for the front, basically giving me 2in of lift all around. This still wasn't enough for what I put the poor thing through, so next step was ordering the "Timbren Suspension Kit"
The kit cost me under $400 for front and back, which I thought was reasonably fair considering the high build quality. The install was straight forward, and could be done by any monkey with a toolbox, unless you have my luck, then the bolt head will strip INSIDE the factory rear bump stop and you will spend 4 hours and every trick in the book getting it out!!!, but lets hope you don't have my luck.
The rear system is nothing more than super big, strong, heavy duty bump stops that allow about 3 inches of travel before they assume all the weight of the bed / trailer and relieve your leaf springs. When not loaded, you get factory ride.
The front system has a bracket that bolts to the frame, and another big, strong, heavy duty bump stop sits on that bracket and will hit the lower control arm when loaded ( as in raising a plow ). Again, When not loaded, you get factory ride.
Overall it was one of the better things I have done for my truck, and it seems that I could transfer the rubber bump stops to a different vehicle if I had new brackets, which is a plus. I give it a 10/10.
This is the video that sold me on the kit,
