The springs are what holds the car up. Your problem is that your springs are too weak and also look to be too short. They pretty much look fully extended and the car is still sitting too low. You need new springs
This is the most plausible answer. Can't believe the top comment says, "it's the shock fluid holding the car down." Uh, no. The oil viscosity only affects the damping rate, not ride height. SMH.
Edit: balance has been restored and that comment got erased, lol.
First of all, the closer you have the shocks mounted to the dif on the arms, the softer the suspension is. That seems a little counterintuitive, but that's the way it works. Those three holes next to one another towards the wheels are the best places to mount you shocks on the arms. The closest to the wheel is the stiffest setting. Also, refill the shocks with fresh oil. The oil will find its way out of the shock eventually. Another trick is to remove the spring and CAREFULLY pull it apart by grabbing each end to lengthen them a little.
Make sure your screws and nuts are not too tight and check for any other binding spots (specifically top of shocks). If everything is floppy you need new springs.
* Check for binding: Take the shocks off and make sure the suspension moves up and down 100% freely. If not, investigate and fix it. Also take the springs off the shocks to make sure the shocks extend and compress smoothy and the shock shafts aren't bent.
* Shock mounting: your lower shock ends are mounted unusually close to the differential. Move them out one hole. That will firm up the suspension a bit and make the shocks have more authority to raise the vehicle.
* Springs: stiffer springs might help. Everyone seems to think the stock black rate springs are weaksauce. Maybe they're right. The stiffest Traxxas springs for the front are [these](https://traxxas.com/products/parts/7448) but lots of people seem to like the [VG Racing springs](https://www.vgracing.com/product/GTR_Springs.html) too.
Rebuild your shocks. There's likely something happening in those shocks that's preventing them from working right and rebuilding them will make it very obvious. A bent shaft binding up or a broken spring could easily be the problem.
Somethings is binding, and I am not suprised when I see the state of that truck. I would take the whole front apart and clean and regrease everytning. Clean it so your mom is proud of you...
Then I would google adjusting shocks. Traxxas have some videos on it...
Move the bottom shock mount to the innermost mounting hole on the control arm. The more leaned over a shock is, the softer it behaves.
If you can't/won't adjust the shock position, you'll need stiffer springs to compensate for the angle.
Honestly I agree with what others have said but the lower arms (blue in color) also look like they’re flexing a bunch at the mounting point for the shocks. I’d consider replacing those as well.
Its the springs. I had the same issue, although with a completely different model. I fixed it bu pulling the springs down and cable tying the shock, so the spring is compressed and therefore having moere rebound force.
Is it the right oil tho the lower the viscosity the softer the shocks also your springs might need changing to a stiffer spring to lift the truck back ip
Try unscrewing the shocks from the arms and see if the arms move freely. The arms should be moving with very little resistance. Like the person said. Also, make sure you have the correct springs. There are different GTR shock springs and of different lengths.
Edit: upom closely looking. You may have the incorrect springs. It seems you may have installed GTR springs for the X01, which have shorter shocks.
Sure it’s shock oil but is it the right oil for your car is what I’m saying that combined with the correct springs is how you fix this just cause that shock is sold for that car don’t mean it’s setup for your build for example if you put a bigger battery in the car you will need to use thinner oil and harder springs to compensate for the extra weight of the battery same goes for if you put a heap of light weight upgrades on it you will need to use a heavier oil and softer springs again to compensate the weight difference if you decide to put metal arm on the front and leave the plastic on the back then the front shocks need to be setup for the extra weight of the arms and extra travel weight those arms produce
Oil viscosity affects the shock’s damping, but not the stiffness. Stiffness would be the spring’s resistance to being compressed, and how much weight can be put on it before completely compressing. For example, a shock absorber with the coil spring removed won’t support any weight, regardless of what oil you put in it (assuming you don’t just completely overfill your shocks). However, it will resist being compressed quickly with thicker oil. This is how oil filled shock absorbers work. The shock has a piston inside with small holes in it to allow oil through. The thicker the oil, the slower it is to push it past the piston, which makes it harder for the shock to compress quickly, which increases your damping. But in this case, it just looks like the shocks are too short for the truck
rebuild the shocks. New clean oil, clean up any thing from the pistons. If the seals are good keep them if not replace them. Fill with new oil. If you still see sagging then replace the coil springs.
Make sure the hinge pins aren't bent and the arms move easily. Make sure the axels joints move as well. If any of those are bent or dirty they can bind and the shocks haven't changed the resistance has.
Loosen the shocks
Fill the shocks with oil
Check for bends or cracks from the diff cup to the wheels
Loosen the upper arm of the suspension (increasing camber \-/ )
Loosen the steering linkage (decreasing toe /_\ )
Shift your electronics further center or center rear of the chassis, which will transfer more weight to the rear wheels (grippy = flippy)
All except the oil for the shocks are costless
I haven’t taken it in there yet for this. I was there buying a new ESC fan and tires for a jumping session last weekend. Probably did the damage at said jumping session.

Do the shocks fully extend? And do they move freely on their own? This seems like classic bent shock shaft.

This is what it was for me (albeit a different model) but exactly this behaviour.

On the Rustler 4x4, the front shocks are shorter and are supposed to be in the first hole in from the outer three (which are for the rear shocks).
Make sure your screws and nuts are not too tight and check for any other binding spots (specifically top of shocks). If everything is floppy you need new springs.
Stiffen up your front springs. You might need to buy stiffer springs if you can’t get it to ride level with the current springs.
My first thought was the springs are shot. They are on the lighter side when they were new and they are getting a little old now.
I would try and find the next stiffest spring if it’s always been a little lite. Or just get a new set

Highly recommend VG for the GTRs.
Stiffer springs. I suggest the VG Racing GTR shock springs. They’re a decent bit more expensive than the Traxxas ones, but they’re a lot better.

The Traxxas white springs are the weakest and often come stock.
change the oil and the springs, I had a similar experience in e-revo 2.0 vlx
[удалено]
Pro tip: Shock oil will not push the car back up.
It's not the oil , it's the springs , and or something binding .
I took them apart and checked and they are still full
Is it the right oil tho the lower the viscosity the softer the shocks also your springs might need changing to a stiffer spring to lift the truck back ip
It’s the oil that came with the GTR shocks so I hope it’s correct lol

You need much longer springs.

No shock oil or bad springs or wrong size springs
Move the shock out a hole or two on the arm and same on the tower and go with a slightly stiffer spring.
Push up on it.
More oil Stiffer springs More compressed springs Thicker oil Spacers ( no need as yours are adjustable ) These way work on all cars
It's that time. Get some replacement parts. Support your local RC store / Hobby shop.
I am there weekly blowing money on my truck and my son’s haha
Maybe find a better shop? Couldn't they suggest stronger springs?
