Review: Fantastic fit and finish, and easy to install. - These aren't full portal covers: they are heavy (76g per weight) portal weights that attach over the stock plastic portal covers with just two screws each. They might work with the Traxxas aluminum portal covers. The fit and finish on these weights is better than many of the higher priced brass parts I've purchased over the years, and these are less expensive. They install super easily: it only requires removing the top two outside portal screws and installing the weights with the two longer screws provided with the weights. That's it! The weights fit perfectly to the postal covers with absolutely no slop. Lastly, the price on these weights is great. Review: Great! - Fit and finish was great. Such a simple weight upgrade, wish I knew about these sooner! ## Features - 【Compatible with】fit front and rear axles, can work with the stock plastic inner portal part without spacers.
