Riffraff frx install Q
Im going to be putting this on this week. There is one part in not sure of.
5.Choose which spring you want to install to get the pressure desired
(Silver = 58-61 psi, Gold=62-65 psi, or Black=67-70 psi )
Which spring do i want to use?
I will also be doing the hutch mod, and installing a hydra chip. As my sig says i have a 6637 and 4" turbo back.

Just difference in opinion, some like more. We haven't ever seen any evidence of a benefit though.

I prefer the Gold spring too. My truck has always run well with it.
