I've been looking into doing a coilover swap and I can't seem to find what length springs I will need. Its going to be on a superlift truck. I know I need 6.5" travel shocks but what would be the right spring to go on that or can you run a dual spring setup on that?

 

You need a 12" spring as for rate it's up too you 600lb to 800lb are popular. I am running 700lb springs but have a lot of extra weight on my front end with the winch and winch bumper.

 

Thanks! I'll eventually be building my own winch bumper. Where did you get your shocks from?

Will it cost extra to have the shocks custom valved or is there a recommended valve setup for our trucks?

 

I have Fox Hypercoils.

I believe ORW can get you properly valved coilovers
