New Motorsports Shock valve building service


This is cost per shock when you purchase new Motorsports shocks that don’t come with a valve stack (usually only Bilstein SN, ASN and custom off-road) and includes development of critical damping curves, installation of valving and testing.

New complete systems from Bilstein, Moton and AST do arrive complete with valving ready to bolt on.

We will create a custom valve stack for your specific car and type of motorsports; here’s what we’d like to have from you (but if you don’t have all of this information we can help you too!):

  • Car, class, racetrack(s) (need not be overly specific)
  • Corner weighs
  • Unsprung weights
  • Spring rates
  • Motion ratios
  • Anti-roll bar rates (or dimensions, diameter, length of arms, motion ratios)
  • Any aero devices, ground effects

More info is better but we don’t need more than spring rates and type of car to get started.

You can call or use our Contact page, you must include your order number so we can place your information with your product.
