Yes, this is exactly what I did. I have one of the first runs of the sc10 4x4 from tower. I ran it alot, box stock and didn't think I had any slipper issues or suspension issues...my truck seemed to be as fast as anyone else out on the track. I didn't think I had suspension issues since the truck was new, myself & everyone else was learning about the suspension and the new style shocks, and I was excited about the x-rings...they should work better in theory than standard o-rings.

So when I saw trackstar come out with their o-rings, I had to ask myself why would they feel the need to do this? So then I took my shock off and checked it out thouroughly and noticed that the shaft movement was not very smooth or as smooth as I think it should be especially with these new x-rings that have less contact than a traditional o-ring. So I plopped down $3 and got the o-rings and in my opinion they are the best bang for the buck upgrade for this truck hands down. I believe you really don't even need the nitrate coated shafts or hard anodized bodies for the shocks to be any smoother...but they do look better than the stock blue bodies!

As for the clutch basket, I bought that mostly on ALOT of peoples word of mouth here on rctech and at West Coast raceway. My stock clutch was pretty much locked and I just didn't like the fact that I had to have it almost locked for it to work properly. I have the basket on my truck now but I haven't had a chance to run it on the track yet...I'm hoping to this or next weekend and I'm excited to feel how it works based on everyone's positive feedback.
