The Losi Rock Rey 1/10 4WD Electric Rock Racer Kit is most at home in rocky terrain - the rougher the better! The Rock Rey kit includes a host of option parts right in the box, so grab a handful of trigger and let her eat! Because its a kit, you have the freedom to accessorize and build the rig how you want it right out of the gate. With a revised roll cage that resembles full-scale rock racers, combined with revised front-end geometry, aluminum rear upper links and upper rod track mount, adjustable camber links and steering turnbuckles you get the durability and tuning options necessary for competitive rock racing.

Losi Rock Rey 1/10 4WD Electric Rock Racer Kit
Easily the ****iest kit I've put together in the last 20 years. I've never gotten a full pack through without it breaking, and thats on 2s. Did research on the weak points so I upgraded the carrier, ssd front diff housing, aluminum bell crank/servo horn, MIP driveshaft when I originally built it. Now I can't keep the diff cups from exploding, or screws from failing in front or rear diffs, diffs need an upgrade option badly and not just twin hammer diff cups/protek screws...it needs something made for this truck specifically to fix that. Wouldn't recommend to anyone that wants to U4RC with it, would probably stay together as a crawler, but its a rock racer so....)
