6point roll cage and a 1500 RTI score (practically on it's side going up some extreme hill)" Uhm... just having fun there. Show me a truck that does that and I'll show you a truck with a linked suspension and coils or coilovers. Or air bags mounted waaaay up the lower link. 1500.......Sorry man, you'll never......... ever............ get that with leafs. I'm currently building a 3-link for the rear of my pickup. I've got 10" lift now with 42" swampers. Articulation SUCKS ASS with 10" springs. She's a great muddog but crap, thats why the coils are goin in. With the 350 SM465 NP205 the drive train is stout, but I'm a little high with 4.56's in the diffs, I'd be alright with a BBC but for a SBC I should be at 4.88 or even 5.13 for some good grunt. For you, you won't have bump steer with 4" of lift, if the steering's tight through the joints. Here's the specs for a 1990 K5. What I basically want to be able to do is tackle some rocks (we really don't have that many outcroppings around here, even though the nickname is the 'granite state') - but mostly fling mud around and generally make a mess. It's my daily driver so I want it to look tight and ride relatively comfortably. Starting to think maybe a 2" block, 2" spring, and 1-2" body lift would be the key? That would keep my springs flatter for a smoother ride, and better articulation. Or even do a shackle flip in the rear and get some new shackles for the front? The blocks/body lift would give me that extre height after that to finish the apperance. Then pop some 33" whatevers on there and I should have a mild trail rig. Maybe some sort of locker down the road... ~KJ~ [ Top ] =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0Year: 1990 Production Total: 18,921 =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0Base Price: 16,485 Weight: 4,839 =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0Wheel Base: 106.5 in.
