My issues were mostly front a-arm and Diff stripping. If I ran plastic a-arms, they broke; If I ran aluminum a-arms, the pins and retainers bent or broke. I couldn't tell you how many diff. gears and pinions I went through, but It was a lot. The only drive train issue I've had on my mostly stock 8ight-T after almost a year of racing was the front cvd pins sliding out but a little lock-tite and heat shrink solved that problem. It has the original a-arms on it and I haven't even ever shimmed the diffs. Just change the fluids and drive. I'm not saying the LSP is a bad truck, especially considering the price. But if you spend the money on the modifications needed to make it a little more durable, you've spent what you would have(or close anyway) on an 8T. Of coarse, it's only my opinion.........
