Spin free and work great for a traxxas slash 2wd stock or aluminum bellcrank.

I used these inside a diff housing so they dont see much dirt etc, but they have held up great for a couple YEARS so far... So yeah Id say they are high quality.

I put this bearing in my Losi Tenacity MT because he come with plastic bushing, it just perfect and turn better than ever more precision. I will buy again for my ARRMA Big Rock crew cab. Thank you AMAIN and Protek for the quality product !

James WilliamsVerified owneron ProTek RC 5x8x2.5mm Metal Shielded "Speed" Bearing (4)

I bought these to replace the bell crank bearings in my Yokomo YZ-2. The stock Yokomo bearings only lasted about a month. I've had these installed for about 6 months. They are still working great.
