This precision replacement wheel is intended for short-course and monster truck style models listed as compatible and is supplied as a matched pair to provide left and right wheels for track width adjustments or component refresh. The red finish complements aggressive setups while the 40 Series offset shifts tyre contact outward to alter roll centre behavior and stance.
Compatibility is constrained to the exact model names specified by the listing: Traxxas Revo, HPI Savage 21, HPI Savage 25. Prior to installation, verify hub bore dimensions and wheel nut engagement on the target chassis to ensure correct seating and preload.
Technical fitment notes: these wheels are designed to use the vehicle's original wheel mounting hardware; apply specified torque values, confirm clearance at maximum suspension compression and steering lock, and assess handling changes incrementally. When tuning, monitor tyre wear and cornering balance after each adjustment.
