I don't. It will do 60 in the rough sand washes in Farmington easy, but would need more shock if you want to go faster in the rough stuff. The radius arms/3 link work really well for high speed runs! Super stable running fast and doesn't ever unload like some 4 links.
Worked really well in the Hammers, I hit my fastest in it which was upper 70's but I started to feel loose on the lakebed by Hammertown, so, I shut it down. It's not an Ultra4 but it also doesn't crawl like one, that's a good thing, bc it crawls better.
If it's not to wet out, I might be able to get a vid of a fast run next week sometime.
Give me a call or text if you have more questions.
