1/30 Axial SCX30 Upgrade Parts

Yes. Brass parts lower the center of gravity and add front/low weight, improving climbing and stability.

Most SCX30 drivers start with:

• Brass steering knuckles – often the most effective first upgrade for front-end traction
• Brass diff covers – add low axle weight for better crawling stability
• Brass skid plate – adds weight low in the chassis to help lower the center of gravity
• Brass wheels / wheel weights  – add low rotating weight and improve stability and tire contact

Note: A balanced setup works best. Too much brass can reduce efficiency and increase drivetrain wear.

A servo upgrade is especially useful after adding heavier or larger components.
You may benefit from a stronger servo if you install:

• Larger tires
• Heavier wheels
• Brass parts
• Wider axles
• A more demanding crawling setup

A higher-torque servo can provide:

• Stronger steering under load
• More precise steering response
• Better control on technical terrain

Metal gears can also improve durability for crawling use.

Many SCX30 owners upgrade to brushless systems for smoother low-speed control, better throttle precision, and improved crawling performance.

However, it is a more advanced upgrade than a brushed motor swap.

You will usually need:

• A compatible brushless ESC
• A new transmitter and receiver

Additionally, the electronics should be compact to fit the limited SCX30 interior space.

Because of these requirements, brushless upgrades cost more and require more planning than simply swapping a brushed motor, but they deliver a noticeable improvement in control and driving feel.

The best tires for the SCX30 depend on whether you prefer a realistic scale look or maximum crawling performance.

Soft compound crawler tires usually provide the best grip on rocks and technical terrain.

Larger and wider tires can also improve traction and obstacle clearance.

Many SCX30 drivers also upgrade to beadlock or brass wheels to improve stability, traction, and overall crawling performance.Tires are widely considered one of the most effective upgrades for the SCX30.
