As Ard stated, suspension wise, go with whatever OEM is. FCP is good about giving that info. It will be the same thing the truck came with, and will still be substantially cheaper than OE.



I've never used the AT205 but have heard of others using it with varying levels of success. Anything short of fixing the actual problem is a band aid. Personally, I use Lucas oil additive and heavier oil to alleviate the smoking until I have the time to dig into the N62 and replace all the common failure points (VSS, crossover pipe, timing cover gaskets, motor mounts, alternator mount gasket, etc). But again, this too is a band aid and not a solution.
