RCarmumb Aluminum Front Steering Knuckles & Rear Hub Carriers Upgrades Part for Arrma 1/16 Mini Kraton 3S vs Arrma Mini Kraton 3S Aluminum Front Hubs

Buy the RCarmumb set if you want to upgrade the whole front and rear of the truck in one go, since it covers both steering knuckles and rear hub carriers. Buy the JTeamhobbies blocks if you only need the front and want the stronger 7075-T6 alloy with wider bearings. Both are direct-fit aluminum replacements for the stock plastic parts, and owners of the Mini Kraton generally report less flex and fewer breakages after switching to metal. The RCarmumb set is the broader package; the JTeamhobbies part is the more refined front-only piece.

• Choose the RCarmumb set if you want front knuckles and rear hub carriers together and a complete aluminum swap on your Mini Kraton 3S.
• Choose the JTeamhobbies blocks if you only need the front and want 7075-T6 alloy with oversized 7x14x5mm bearings.
