STOP Traction Rolling | Losi Super Baja Rey Shock Tuning & Spring Upgrade

Shock tuning is critical on the Losi Super Baja Rey to get it to run better and stop traction rolling. I found that by upping the shock oil, and adding slightly stiffer springs from GPM the body control vastly improves.

So in this video, we will go through how to tune the shocks and how to make the truck handle better. This is an absolute must for any Losi Super Baja Rey especially if you drive on high traction surfaces and keep rolling your truck.

I'll need to try this for when I'm on grass. The stock tune is fun to watch because it's so plush and squishy but the traction roll !

[jamiea]

Sbr2's sound so angry loud ! Ive had one or two peeps ask me if it's nitro 😂.

I’ll definitely need to tune the shocks for mine because I’m running a 12s system.

If anything, front shock oil should be heavier since front springs are stiffer. Also you should bleed the shocks. Fill to the top. The only air inside should be above the bladder, not below it. Loosely put the cap on, then compress the shock to push air and excess oil out. Keep it compressed and screw the top all the way. Some people like some rebound, but you have full rebound with excessive air and pressure.

The main thing is adding a second shock piston in the rear behind the existing shocks, but you can probably leave the spring off. That adds so much extra dampening that the negatives of a solid axle trophy truck design are countered without losing the awesomeness of all that articulation and travel. But I'm also really interested in possibly increasing the diff oil viscosity in the rear and even more dampening in the front shocks with some thicker oil possibly as well. I've solved the problem for the super Baja. Ray but the super Rock Rey is twice the pain when it comes to rollovers and donkey kicking. And the super Rock Ray breaks when it crashes, unlike the SBR 😞... Hopefully some of the shock tuning in this video may help!

My sbr2 shocks were basically empty too, I filled the front with 60wt and rear with 80wt

The reason you were getting traction roll is because there was no oil in them. Higher viscosity (higher number) oil means the body will be slower to roll keeping the CG more centered on the chassis for longer. Lower viscosity will lead to body roll as the fluid travels through the pistons faster and more of your CG will get to the outside tires faster leading to a roll over. Much of the rollover tendencies actually isnt in the shocks as shocks just absorb impacts but instead is in the tuning of the sway bar. Thicker sway bars will transfer forces and distribute it through both wheels. I must also include tha GPM parts suck, especially their springs as they will start to sag dramatically in less than a month.

I did 50 front 60 rear and put the rear firm springs on the front and rear. Thats right put rear springs in the front. I've just uploaded a video that shows the results

[ric_fu]

New subb for me i'm really interrested .. normally it's a futur project to have a baja and we could see a lot of vidéo... that s complicated to drive correctly the baja without always ending up on the roof😅 great présentation friend 👌have a fun day 😁👋🇫🇷

[marcanthonystorm]

Great video. I’ve watched it a few times already. What kind of tires do you have on there.🔥🔥🔥🔥

[FOURFTP]

Im new to RC and I’m trying build my senton can I add these King Shocks ? 100mm or should I go with the 90mm

[bigboyblue]

I just emailed Horizon Hobby. They said 60wt oil is used in both front and back from the factory.

[Johnnyex]

Dude increases the throttle. You yst messed up the suspension on that truck that was on point

[xiuhdj]

where did you get your tool box? Pelican? SKB?

[Angry-Lynx]

She needs a little stiffer springs but i would left dampers oil weight stock, unless you do big jumps this car is not meant to do anyway ;

[gilibran]

This video helped alot with retuning the shocks for my SBR but i had issues with the rebound not being consistent between the shocks. Eventually found this old video from Losi that helped me tune the rebound for these bladder type shocks as close to perfect as i could whish.

[Kyletube]

What are the part numbers for the springs?

[nobody]

Superclean is super harsh on aluminum and seals, so get it off quick. Simple green isn't like that

[davidnieves]

I’m gonna go ahead and assumed you mix two different oils from two different manufacturers because that’s all you had next time just use a 42.5 weight

[Roseabovethis]

The video quality isn’t the greatest, it cuts out and lags throughout. Just figured I’d let you know
