Default Droop/sag question.

So I've just cleaned and rebuilt my shocks, silicon oiledy o rings and have loosened the bottom collars a quarter turn with a drop of thread lock. Running 15wt oil and they are super plush. Even better than new. My question is is what do you guys prefer, max articulation or donyou run stiffer to pull yourself over obstacles, also side hilling... Is droop better as a lower COG or does it make it more difficult with sag?

I run about 70% droop on my rig with 15wt oil. I have tried no droop, 40%, 60% and full droop. I have found the sweet spot that I like on my rig by testing over and over. No droop made it more top heavy. Full droop I wasn't getting clearance that I wanted on my tires. I think it's all a personal preference. Allot of the guys that run full droop also run really heavy shock oil in the 60wt-80wt range. I have been thinking about switching to 60wt just to give it a shot. Your best bet is to set yourself a few gate course, slow crawl, watch what you're suspension does, watch what you're chassis does and adjust from there. That's what I did and it really helped me improve my truck's ability. Hope this helps you some. Let us know what you come up with. Good luck!

What weight is the stock Traxxas shock oil that comes in the kit?

I think I have my lower collars to tight after reading this. I’ll loosen and re-try.

I have my droop setup where there is no tension on springs and 20 weight team associated oil. Keeps my center of gravity low and crawls like a champ

This is an area where you just need to test different spring rates, oil viscosity, weight, etc. for yourself. What works for me may or may not work for you and you just need to try different settings until you find a setup you like. For reference, I run about 60% droop with .30 springs and 20t oil.

I like the way the suspension moves unfortunately you can actually see the tires bouncing off the ground in some shots which is exactly what shocks are designed to prevent.

I wonder if something as low as 5-10wt oil ( do they even make 5wt) would calm the shocks down enough to prevent the tires from hopping off of the ground?

Any shock damping action will help. I run 10wt in some of my rigs and they move very much like the video. I have never filmed them so I could watch the movement in slow motion.

If all I was doing was speed runs across washboard surfaces I might give that a try. I'd be interested to see this setup on the rocks.

My truck sits "static" at about 2/3 sag. It weighs 9.5-lb with Associated (Lucas) 10-wt oil and Traxxas' .30 springs. We mostly rock crawl and I found this set-up seems to work the best, so far. The light oil (and loosened bottom caps) lets it move free and easy, and the softer springs let it settle, but lets me tighten the collars enough to keep a little spring pressure at full extension. That helps keep the tires on the ground when it rides the skid-plate. Just my 2 cents. It really comes down to where and how you drive too.

Yep I run 15wt, very smooth.

I just rebuilt all 6 of my TRX-6 shocks again, but THIS TIME using the white spacers from the Ultra Shock rebuild kit. THIS is exactly how it should come from the factory... that thinner white spacer allows you to torque down on the lower cap AND the shocks are Über smooth now. I still used some green slime too.

So now I’m running the orange .39 springs up front, yellow .22 springs for the intermediate, & .30 white springs on the rear axle. All Shocks have Factory Team Associated 15wt (150cst). I’m also running a different geometry using Samix parts & some slight alpha angle. I’m getting about 50-60% sag and the stability is 400% better than stock.
