1/24 Axial SCX24 Upgrade Parts

Yes. A small amount of brass improves stability, but too much weight can strain the servo, motor, and drivetrain. 

A good balance is:

• Brass wheels / Brass wheel weights
• Brass steering knuckles
• Optional: brass diff covers, links, skid plate

Tips:

Avoid adding heavy brass everywhere — balance is important. Focus weight low and on the front axles for the best results.

Yes. Pros:

• Higher Ground Clearance: Easier to clear rocks and obstacles.
• Better Traction: Larger or softer tires improve grip on various surfaces like rocks, mud, and sand.
• Aesthetic Appeal: Gives a more aggressive, "scale" look.

Cons:

• Higher Center of Gravity: Increases risk of tipping on slopes.
• Reduced Torque/Power: The motor has to work harder, resulting in slower speed and less climbing force.
• More Drivetrain Wear: Extra stress on motor, gears, and driveshafts.
• Potential Tire Rubbing: Tires may hit the body/fenders when turning or flexing.

For most SCX24 builds, 57–62mm tires are the sweet spot.

Not always. The stock motor can handle light to moderate weight.
But you should upgrade to a stronger motor if:

• You added a lot of brass
• You installed larger tires
• You want more low-speed control
• You notice overheating or reduced runtime

Both brushed 050 motors and brushless systems are excellent choices depending on your driving style.

Upgraded shocks provide several advantages:

• Smoother Suspension Movement: Reduces bouncing and helps the truck stay planted.
• Better Traction: Keeps the tires in contact with the ground for improved crawling.
• Improved Articulation: Allows the chassis to flex more naturally over uneven terrain.
• More Stability: Helps the vehicle handle slopes and obstacles with better control.
• Tunable Performance: Oil-filled aluminum shocks let you adjust damping to match your driving style.

For the stock SCX24, you mainly need:

• 0.5" / 1.27mm / 1.3mm Hex Drivers: Used for most screws on the SCX24.
• 1.5mm Hex Driver: For the two motor-mounting screws.
• 4.0mm Nut Driver: Used for wheel nuts.

For upgrade parts, you may also need:

• Small Phillips Screwdriver: For stock screws and some body parts.
• Needle-Nose Pliers: Helpful for links, shocks, and small hardware.
• Hobby Knife: Useful for trimming tires, bodies, or removing parts cleanly.
• Tweezers: Great for handling small screws and nuts.

These basic tools are enough for almost all SCX24 maintenance and upgrades.
