Hobbypark Front and Rear Heavy Brass Outer Portal Covers Weights for TRX4 Upgrades fit TRX-6 Crawler, 73.5g/Each (4-Pack)

Were very easy to put on, two screws, seem of good quality. I highly recommend. Edit: I would suggest using +3mm hexes with these portal weights, my 2.2 RC4WD wheels did not seat all the way on the stock hexes. I don't know about other wheels.

Fit and finish was great. Such a simple weight upgrade, wish I knew about these sooner!

Easy upgrade for trx4. I installed these on trx4 72 blazer high trail, installation was easy! Just remove two bolts and install them with the longer included bolts. Great quality and good much needed weight down low

Your wheels will be locked if you don't install spacers

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.

These do not fit on the Traxxas aluminum Portal housings. Unless I am just missing something. Maybe I can repurpose them onto my other trx-4 so not a total waste but meow I need to find some weights for down low.

Was looking to add some low weight and weighted tires are so complicated for someone new to this. These were way heavier than i expected. These weights worked perfect and fit great. Definitely added some weight.

These fit perfectly on my TRX4 and added much needed stability.

Ces contre poids s'emboîtent parfaitement aux autres contre poids de la marque AMK que j'ai déjà sur mon trx4. Je les recommande pour ajouter beaucoup de poids.
