Im doing a front and rear d44 swap and was wondering if yj springs would work or is the hb king cab to heavy

I think your truck would be a bit heavy for those.

how much does my truck weigh I know the yj is about 4000

if your using the calmini kit, it's designed to be used with waggy springs. As for the YJ springs, our trucks are way heavier than a jeep wrangler.

You will easily have negative arch if you run yj springs. If you'll like some cheap alternative look into rear s-10 springs. I think there about the same length as the waggy's.

If you need a sas parts list you can check my build thread.

there is someone on here who has a white pathy, running 4" yj lift springs up front... he says they work great for now, but he's going to the Wagoneer lift springs (rancho)

I asked him about the springs earlier this month (as I'm trying to price springs for my Pathy as well) and he said that the work fine and flex great... but not expecting much life out of them as the Pathy is a heavier vehicle than a Wrangler...
