Replace the stock plastic upper arms with machined aluminium parts to stiffen the front suspension mounts on Hotshot-series vehicles. The design keeps the factory geometry while offering improved dimensional stability under load for better repeatability.
Fitting is intended for technicians familiar with Hotshot maintenance: remove the plastic arms, transfer pins and any bushings, then secure the aluminium arms with the original hardware. Verify ball stud seating and full steering travel during reassembly to prevent binding.
On-track impact: these arms reduce unwanted flex, which helps maintain consistent steering input and reduces unpredictable behavior during jumps or aggressive cornering. Treat them as a mid-stage upgrade alongside shocks and link tuning; small suspension adjustments may be needed to fine tune balance after installation.
Choose these arms for a more rigid front end and predictable setup work; always check clearance and steering geometry after fitting and test thoroughly before competition.
