shock limiters

What are shock limiters, and how are they used to control droop on an RC car? Read on for answers.

Diagram of shock limiters and other parts for an RC car shock

Shock limiters are spacers that are placed on the shock shaft. Internal limiters go inside the shock body, and external limiters go outside the shock body.

Together, internal and external limiters control the shock's stroke and also the car's overall droop, unless it is limited elsewhere via a downstop.
