Alterktion front suspension, wheel size ?

Do you think the 12" spring and shock mount mod would work while leaving the control arms the same length?

I don't see any reason why not. Depending on tire size and desired ride height, you might even be able to go a step longer.

He simply knocked the shock mount brackets off the K and bolted the rest in. If it were me.....I would install threaded tubing ends / adapters to the control arms and add heims or poly ends to make them adjustable.....but that's me. I like the ability to change and adjust some things.
