The lift came with 2" blocks which I installed, I'm not sure if that is 4wd block size or not. Is it true that it is "bad" for your truck, or not as safe for me to install a 4" or 5"?

 

Sorry for the angled pic, driveway is on a hill

Fabtech 8" lift kit w/ 33's. Time for some new tires 👍🏻

 

I think a 2" block and an AAlin the rear would give you the lift you want back there.

AAl is gonna ride stiffer as noted. But you may not even notice. Some do, some say it didn't affect the ride much.

What's the exact different in measurements from front to rear? Measure from the center of the wheel to the fender arch for the most precise measurement.

 

From the center of the wheel to the top of
the wheel fender:
27 1/2" Front
24" Rear

 

Blocks are not "bad" for your truck. What they do is give leverage to the axle increasing spring wrap and thus wheel hop in limited traction situations.

The axle wants to turn the opposite direction of the wheels. Part of the job of the leafs is to stop that. What happens under high load is the spring begins to twist like an "S".

Adding blocks is like you adding a bar to a wrench or ratchet. More leverage to twist your springs.

Bad for your truck, not exactly but makes a small issue a bigger one potentially.

 

Thank you, very well explained for a noob like me!

So if I just drive highway and don't off-road with my truck, what exactly is the "small issue that could potentially be bigger"?

And would that affect a "mall crawler" truck like mine slightly, or severely?

 

If you're not rough on your truck and not accelerating as fast as possible all the time, you would probably never see any signs of axle wrap.

 

Thanks for all the help guys! I'm gonna order the lift shackles and then possibly swap the 2" block out with a 3" or 4". Once the parts come in and get installed I will post updates

 

Agreed, for a pavement princess blocks are the easiest and cheapest option.

I have stock blocks in the rear and have issues with axle hope from axle wrap when off road. It's a good way to break stuff However when I am off road it is often not light on the throttle. I don't go looking for off roading but run into it due to my hobbies of hunting and fishing in remote areas.

 

Yeah I know what you mean...whenever I'm going hunting or fishing or just to play, its always in an older truck. I drive this truck like a grandma lol! Once I get a new truck in a few years, then I will use this one to drive out on the property when hunting, etc.
