PhillipVerified owneron Hot Racing Arrma Limitless/Infraction Aluminum Rear Chassis Brace (Black)

Easy replacement, uses same alignment tab through chassis as stock. Would have preferred a modification to allow 2 attachment points to chassis, like repurposing the slot in chassis for tab to a second mechanical fastener.

Great detail and quality. Reduces a bit of flex in the chassis especially when installing both front and rear braces.

Fit my Arrma Felony perfect. Im about 75% aluminum.

What reviewers say

Three verified owners rated this aluminum rear chassis brace 4 to 5 out of 5. Reviewers report it installs as a straightforward replacement using the same alignment tab through the chassis as the stock part. Two reviewers praise its build quality and detail, and one reports reduced chassis flex, particularly when used with the front brace as well. One reviewer would have preferred a second mechanical attachment point to the chassis instead of the single tab. One reviewer reports a good fit on an Arrma Felony, a model not named in the product listing, so compatibility beyond the Limitless and Infraction is based on a single report.

  • + Easy replacement using stock alignment tab
  • + Good detail and build quality
  • + Reduces chassis flex, especially with front brace
  • − Single attachment point via existing tab
  • − Fit on Arrma Felony reported, outside listed models
