Reliable Differential Spacing with Tamiya BA21

The Tamiya 3455940 RC Differential Spacer BA21 helps maintain stable internal clearances inside the diff case to support smooth gear engagement. It is a straightforward, service-friendly component suitable for many Tamiya cars.

Practical Benefits for Drivers

By ensuring components stay correctly spaced, the spacer can reduce chatter and uneven wear, which helps keep handling predictable during both practice runs and competitive events.

Installation and Fit

Fitting the spacer is simple for anyone familiar with basic diff servicing; follow your model-specific notes and always verify gear mesh and bearing alignment after installation.

How do I check if the spacer is correctly seated?

Once installed, rotate the diff by hand to feel for smooth engagement and inspect visually to ensure the spacer sits flush and does not interfere with nearby parts.

Does the spacer need periodic replacement?

The spacer itself is durable, but check it during major services or if you notice changes in drivetrain feel; replace if worn or damaged to maintain correct spacing.

Can I use this spacer when changing gear ratios?

Yes, but after changing gear ratios verify mesh and clearances as different gears can shift how components sit; adjust shims or spacer placement if necessary.

Will this part affect diff maintenance intervals?

Keeping spacing correct can reduce premature wear, but maintenance intervals still depend on use and conditions; inspect diffs regularly when running in harsh environments.
