Just received my 12 way HALS, Hotchkis springs and airbags today. The shocks are extremely high quality. Got em from No Limits. Very happy with the service. Hopefully they're on by the weekend. Now my question is what addition bolts are needed to install the HALS? I was told longer bolts were needed. What size is required? Anything else I need to know about install? Thanks again fellas.
