TAMIYA Hotshot/Super Hotshot Aluminum Rear Knuckle Arms for Suspension Tuning - JR-THS02-BK by Jazrider  [JR-THS02-BK]

Aluminum knuckle arms engineered for Hotshot setups

This aluminum rear knuckle arm set is an aftermarket replacement for TAMIYA Hotshot and Super Hotshot chassis, intended to deliver a firmer mounting surface than typical plastic components. Use it when you want a more consistent pivot while experimenting with rear suspension geometry.

Compatibility only covers Hotshot and Super Hotshot family layouts as described; confirm your chassis configuration before attempting installation. The parts match original mounting positions so you can often keep existing screws and linkages where they fit correctly. No assumption is made about supplied fasteners.

Installation guidance: remove rear hub carriers and the original knuckle arms, fit the aluminum arms to the upright and secure with your existing screws and ball studs if compatible. Apply torque appropriate to small-scale RC fasteners to prevent thread damage. Check alignment and suspension travel after installation before running.

Tuning benefits: replacing stock knuckles with aluminum pieces helps maintain a consistent pivot for toe and camber adjustments, which simplifies evaluating setup changes during development runs. Combine these arms with coordinated shock and roll-center tuning rather than relying on them alone.
