Release / Date Evidence:

Review / Announcement Date: June 5, 2019. Source-backed as a Big Squid RC new-product article for ARRMA LIMITLESS 1/7 Speed Bash Roller, part number ARA109011.

Product Benefits:

Sealed bearing protection helps defend against dirt, dust, and debris during ARRMA bashing and outdoor running.
Better choice for off-road, dusty, dirty, clay, parking-lot, and debris-prone RC use when protection matters more than lowest rolling drag.

Reason to Purchase:

Choose rubber shielded bearings for this ARRMA model when sealed protection matters more than the lowest possible rolling resistance. They are the stronger fit for bashing, off-road abuse, dusty surfaces, and mixed-terrain running compared with metal shielded bearings tuned for cleaner low-drag use.

Fitment Note:

Confirm your ARRMA vehicle model number against ARA109011, 109011 before ordering. Do not assume fitment with other ARRMA variants unless the vehicle model code is listed here.
