    Christopher L from Australia

    Great fit and finish. Recommended for strengthening the wheel hubs. They hold the bearings more securely and do not flex compared to the stock plastic hubs. This is an advantage if you drive hard but with care, it is more costly to replace if jumping houses is your thing.

    Other Upgrades/Parts Recommended by Reviewer: I have used GPM parts for all my RCs since 2004. They make great parts. They may not lok as flashy as some other manufacturers, but they are strong and work well.
