This solid-looking chunk of aluminum could be what extends the useful life of your Traxxas 2.5 or 3.3 engine. Machined out of 2024 T4 aircraft alloy, even when it isn’t shown next to a stock connecting rod, the Davis upgrade obviously looks more robust. The other noticeable upgrade is the use of 660 bronze bushings. That it’s machined and not cast makes it more durable and able to take the Traxxas engines’ power output. Other objectives with this beefed up conrod were to stabilize the engine’s idle and promote a longer life for the piston and cylinder. To help lubricate the bearing surfaces, there’s an oil hole at both ends of the rod.

WHAT WE LIKED
• Easy to install
• Much stronger than stock rod
WHAT COULD HAVE BEEN IMPROVED
If you’re comfortable tearing your engine down, installing the rod won’t be complicated for you. If you have never done that, think about asking for the help of someone who has. You have to remove the backplate, starter and pull-start, the head, the sleeve and then the piston itself. It took me 20 to 25 minutes. Keep an eye on the RC Driver forums for a link to a video that walks you through the installation.
