The JRace GVM Approval does not change the factory springs and shocks.
A vehicle that goes through an SSM Pre Registration is considered delivered to the market in that revised SSM condition, same as a how a standard OEM vehicle would be. Therefore any modifications made after this, Post Registration, go through the same process IAW the applicable State Modification laws.
Most states allow up to 2" lifts over OEM to be installed without requiring any testing or certification.
Like any change to an OEM vehicle what is being fitted needs to be fit for purpose. For any modifications requiring testing and certification (ie. lifts over 2") the applicable ADRs all need to be assessed, along with any state requirements to ensure the vehicle remains compliant.
