Hey guys,

I found a lift today that is a block lift 3in in the rear and 4in in the front get it or pass?

 

If you want it get it I guess. What brand is it, JD?

 

I think I read somewhere not to put blocks on the front.

 

Is it spring packs up front JD or blocks?

 

Blocks in the front and very unsafe and illegal in some states.

If that block where to get spitout from under the leaf pack the front axle is no longer attached to the truck and it will not end up well. The front axle sees much for force under braking and steering than the rear axle does.

 

Im not sure if theres any states left that allow front blocks. Either way, blocks in the rear = increased axlewrap. However, with blocks sometimes that makes traction bars more effective, due to the increased distance between the spring, and tracton bar mount. You call. I hate axlewrap myself, and with stock blocks, and beefy springs, built my own traction bars.

 

JD you've seen the lift on mine, 4in block rear, springs in front. Like the others said I would never put blocks on a steer axle. With blocks in the back now, when I take off from a dead stop in 2wd axle wrap is horrible, i'm going to make some trac bars after the turbo and injectors go in. I'm pretty sure something would go very wrong if I tried to launch in 4wd if I had blocks in the front, especially with 35's. IMO I would just wait until you come across rear blocks and front springs.

 

I was just poking around it is an older guy that took them off of his truck when he was calling me about the tool box, I will have him bring them to see if they are blocks or a spring pack for the front. I was pretty sure that blocks in the front were very bad. Too bad the guy traded in his Mickey Thompson 16x10s and BFG 35s I would have bought them off of him. I have a guy interested in trading a 6in but thats just too much for me even his 36x15.50/16 BAJA ATZ Radials on 16x12s look little on it and I hate the fact they stick out past the fender so much. I'll just lurk around some more and see what I can find.

 

Sorry about the but heres some info on the trac bar side of things

Heres a couple shots of the traction bars Ive built. They essentially make the rear suspension act like a four link. I have noticed absolutely no difference in everyday driving, other then there is absolutely no axle wrap. (More noticeable in low speed turning since I have a detroit, because now the springs dont take any of the slack up.) They are not for everyone, because they do take some welding, and fabrication. They have a rebuildable johnny joint in the front, and a polyurethane bushing in the rear. There is no road noise, no difference in ride, with or without a loaded trailer. They really make the rear suspension act similar to a 4 link.

 

excuse my ignorance, but what is axle wrap?

 

When under load, or accelerating, it puts some of the torque into making your leaf spring into an S shape, such as this



This is much more noticeable, when adding lift blocks, and hp, or lockers, or offroading, that type of situation. Normal everday driving, you may not notice it unless you were looking for it. I did, and I fixed it. I noticed it especially in heavy snow, using tire chains. (over two feet of snow, and yes I had to get there)

Now it doesnt make your spring look exactly like that, but it will make your spring start to bend like that, and it can violently go from that shape, back to normal, depending on traction applied, and taking away

 

here is a clip of axle wrap, it'll give you a little idea of what it is

And as you can see when it wraps with enough power it will snap the driveline off and your stuck. I believe Cale at BTS has some killer trac bars on his F-250 drag truck they are adjustable and everything.
