Compare Powerflex sway bar bushings for the Tesla Roadster: 22.2mm vs 25.4mm. Learn which size fits your anti-roll bar and why stiffer bushings matter.
Quick answer
Choose the Powerflex sway bar bushing that matches your Roadster's front anti-roll bar diameter: 22.2mm for the standard bar, 25.4mm if you've upgraded to a thicker bar. Measure before ordering to avoid fitment issues.
Why bushing size matters
The sway bar (anti-roll bar) connects the left and right suspension to reduce body roll. The bushing wraps around the bar where it mounts to the chassis. If the bushing inner diameter doesn't match the bar's outer diameter, the bar won't sit securely, leading to play, noise, and reduced effectiveness.
Powerflex offers two sizes for the Tesla Roadster: 22.2mm and 25.4mm. The correct one depends entirely on your car's front sway bar. The 22.2mm is likely the stock size, while 25.4mm is common on upgraded or aftermarket bars. Always measure the bar's diameter with a caliper before ordering.
Stiffer bushings vs. rubber
Stock rubber bushings soften over time, allowing the sway bar to flex more than intended. This reduces stability and can make the car feel vague in corners. Powerflex bushings are stiffer, reducing play and deflection. The result is more consistent handling and a more direct response from the suspension.
The trade-off is that stiffer bushings can transmit more road noise and vibration into the cabin. If you prioritize comfort over ultimate handling, this is worth considering. However, for most drivers, the improved stability outweighs the small NVH increase.
How to choose and install
- Measure the bar: Use a caliper to measure the front sway bar's outer diameter where the bushing sits. Compare to 22.2mm or 25.4mm. If in doubt, consult a mechanic or the bar's specs. Never guess the size; a wrong-size bushing won't fit properly.
- Choose the right material: Powerflex bushings are stiffer than rubber. This reduces play and improves stability, but may add slight road noise. If you're fine with that, proceed.
- Installation tips: Remove the old bushing, clean the bar, apply a suitable lubricant (if provided), and install the new bushing with the bracket. Torque to spec. Check for any movement after installation. Re-check the bushings after a few hundred miles for any settling.
