HRRUF5501 Hot Racing Aluminum Lower Arms for Traxxas Rustler 4x4

Precision CNC machined lower suspension arms crafted to replace the stock plastic arms on a Traxxas Rustler 4x4, enhancing chassis rigidity and durability in demanding off-road and bashing conditions. Machined from 6061-T6 aluminum and anodized black to resist corrosion and wear, these arms maintain suspension geometry while providing a sturdier mounting platform for shocks and hubs. The set includes two lower arms sized for direct fitment (front or rear) and pre-drilled hinge pin locations to simplify installation without modifying the chassis. Aluminum construction spreads impact forces more evenly and can reduce flex under load, improving steering feedback and handling consistency.

• Two CNC machined 6061-T6 aluminum lower arms sized for Rustler 4x4 suspension geometry.
• Anodized black finish improves corrosion resistance and surface durability.
• Direct bolt-on replacement for stock lower arms with no chassis modifications required.
• Pre-drilled hinge pin mounting holes for secure fit with included hardware.
• Stiffer aluminum reduces flex compared with plastic arms for more consistent handling.
• Compatible with stock Rustler 4x4 hubs and shocks when installed in correct orientation.
• Helps maintain alignment and geometry under impact and high-load driving situations.
