I am having a complete mental block........I have a 67 1/2 ton with a 12 bolt with coil springs....now i realize with leaf springs they sell lowering blocks to put in between the springs and the leaf, or you can flop the axle...now on coils..do they make a block or something to do the same...i just cant invision it...dunno must be the oldtimers disease

yeah, you can get lowering blocks for coil rears... they go between the trailng arm and the axle...I had some 1 1/2" blocks that I got rid of recently... didn't like having the trailing arms that close to the ground so went with drop coils instead.

From what I've been reading, I think you replace the springs with lowered ones, and if you drop more than 3-4" you will need to get an adjustable panhard bar, along with shorter shocks in the back. If I'm mistaken, I'm sure someone will correct me...

yes you can get lowering blocks but the most common way of lowering is with springs. the lowest coil offered is a 6 incher so if you wanna go lower put a block in between it but dont go to low cause i feel the same as ole vinnie on how low that puts the trailing arm to the ground. colohusker is right when hes talking about the pan hard bar. if you go more than 4 inches you need to get an adjustable one cause if you dont your rear end will trail wrong. your also supposed to get a shock relocator kit because the drop puts the shocks at an angle where they dont work as well. well have fun. later

I'm using 4" drop springs and 2" blocks and I havent gotten an adjustable pan hard bar. When I'm riding down the road about 55 & up my truck sometimes kindof sways from one side of the road to the other. Is this what you mean by trail wrong? If so, I'm gettin an adjustable pan hard bar.

Yep thats what they call dog walking. Don't knoow if I'm esplainin this right but in another post I read where the driveline must be right in the middle of the frame. I just measured from the inside of the brake backing to the frame and equalled both sides out. I ended up having to get the adjustable panhard bar. the original threw the rear too far out.

I centered my rear axle by measureing the distance from the outside of the tires to the edge of the bed. Before the adjustable track bar the rear end was about 1" off center. The shock relocaters helped to make the shocks stand straighter vertically.

I'm planing on using 4" lowered coils on rear and 2" on front.Will I need to get shorter shocks and/or adjustable hardpan?
