If you are trying to get it low AND run disk brakes remove the torsion bar set up and get a front suspension crossmember and components from a 85? or older chevy 2wd 1/2 ton pickup. Youll have coil spring front end, you can drag your front bumper with that setup if you want and the whole swap costs considerably less money then the disk brake kit for your truck. I know I just did the same thing. I lowered my truck 4 inches in the front with coils. I have disk brakes, all for 400-500 dollars. Plus the ride adn front sway bar you get makes all the difference in the world. Plus it all bolts right on!!!!
