i am underway on my pmf rsk for 94 f250 with a dana 60 swap and 3.5" with supderduty springs. if anyone has done one of these, do i need to look at more steering upgrades down the road. i have a drop pitman arm from my ttb 4" kit, but i was interested in the crossover steering system since i was going to have an extra passager side steering knuckle to machine for a cross over kit. if anyone runs these please help with any info or expirence. thanks
