Perfect stock replacement!

### ⭐⭐⭐⭐⭐ Cheap and easy
*by M***R on July 11, 2022*

I thought buying an rc car would just be an expensive toy to maintain. The initial purchase is the main cost and parts are cheap. This is another example of that. Quality Arrma parts delivered next day. For under $15 I got the front shock mounts I broke and a spare rear shock mount. About 10 bolts out and back in and 15 mins of time is all it takes.
