Can my K5 conquer this rock? Looking for upgrade advice! (Current build in comments)

Hi everyone!
I'm trying to get my FMS FCX24 K5 Blazer over this specific rock, but it keeps struggling (as seen in the video). I’ve already installed a few mods, but I feel like it needs a bit more performance to clear this obstacle.

Here is my current setup:
Tires: INJORA 1.0" 56×23mm Swamp Claw (S5 compound)
Wheels: INJORA 1.0" Stamped Steel (-3.78mm Offset)
Shocks: INJORA 45mm Aluminum Threaded Oil Shocks
My questions for the community:
Is it even possible for an FCX24 K5 to climb a rock like this with the right setup, or am I hitting the limits of the chassis size/wheelbase?
What should be my next upgrades to get better traction and stability?

I’m currently thinking about adding brass weights (steering knuckles or portal covers) to lower the center of gravity, or maybe looking into a weight distribution tweak.

What do you think?

Any advice on suspension tuning or specific parts would be highly appreciated!

Trail + crawling wheels and tires setup for K5, will this setup work?

Hey everyone!

I’ve had my FCX24 K5 for about six months and mostly use it for trail driving.

So far I’ve only done one upgrade, the INJORA 45mm Aluminum Threaded Oil Shocks, and I really enjoyed the process, so I want to continue improving the rig.

Since the new shocks made the truck a bit taller, I’m thinking about trying bigger wheels.

I plan to buy a universal 1.3" wheels & tires setup for trails, and also get dedicated rock‑crawling tires to mount on the stock 1.0" wheels.

Here’s what I’m considering:

  1. INJORA 1.3" Aluminum Wheels (-5.25mm Offset), W1313
  2. INJORA 1.3" 70×27mm King Trekker S5 Tires, T1314
  3. INJORA 1.0" 56×23mm Swamp Claw S5 M/T Tires, T1021 (for the original wheels)

Do these combinations work well together?
Is there anything better I should look at before ordering?

Update:
Should I also buy “Injora Black Brass High Clearance Chassis Links 39g Heavy Brass Links for FMS FCX24 1/24 Upgrade Part,8PCS (FCX24-04)” to fit for 70mm Tires?

Thanks for the help!
