blocks

[ranger]

i am getting a block lift i already know about shackles so dont say anything about them... anyway since the ranger has a 2in block already can i just remove the 2in and get a 4in because i want 2inches of lift.. i know it is bad to stack blocks that is why im asking

 

[JohnnyU]

Honestly, you'd be best off with the shackles that you seem so afraid of. Blocks are extremely undesirable, even the stock 2" blocks....

 

[ranger]

yes but if i want 2in of lift can i just remove the stock block and get a 4in block thats what im asking im not asking about shackles

 

[JohnnyU]

yes but if i want 2in of lift can i just remove the stock block and get a 4in block thats what im asking im not asking about shackles

2" + 2" would equal 4", so yes....

 

[ranger]

thanks for the help

The reason I suggested the shackles instead of adding a larger block is that your axle wrap will increase, essentially double. That's really not what you want. The shackle will increase your available suspension travel, as well as give you that bit of height without causing mush issue with axle wrap.

Merely a suggestion.

well will it bother me to much if i don't do a lot of off roading besides i don't think my springs are vary soft i have a couple add aleafs

So, I thought I'd suggest against blocks. When we got this Ranger, it had stacked blocks. Look at the deformed spring...

We replaced them with single blocks, but we didn't wish to lose any height.

While this would have passed Utah Safety Inspection, I didn't like this tall block, and since the truck isn't on the street, I have been looking for an alternative. I might have found it. I got a set of Tundra leaf springs that I intend to mount under the frame rails. But, thats a different thread.

avoid the blocking and shackles all together and get some bigger leafs. I have shackles and they work fine. the only ones I would steer away from are the universal bar looking shackle lifts that autozone and advanaced sell.

Yes. It doesn't matter if it's off road. When it matters is every time you accelerate. That is when the problem arises. Don't go over stock block height. Hell get rid of stock block if you can. Blocks are bad.

Johnny U was wrong when he said that doubling the blocks doubles the wrap. Torque is exponential not linear. So if you double the block height you way more than double the wrap. Just my $.02. You won't be happy and this is the voice of experience. I put 4" blocks once......................once.

I put air shocks on my beater and they worked well. my springs were weak, and the shocks were cheaper and easier to install. I tucked the lines up high and out of the way. just something to think about it worked for me. just my .$.o2 worth

 

[JohnnyU]

Torque is exponential not linear.

Torque = r x F Where r is the position vector and F is the force applied. That's a cross-product, not multiplication.

The cross-product of r x F is equal to r*F*sin(θ)* Where θ is the angle between r & F, and is a unit vector perpendicular to the plane in which both r & F lie. No exponents. Multiply r by a factor of "X" (keeping all other variables constant), and your torque also increases by a factor of "X".

 

[Roger]

Now my brain hurts....

 

[brendank]

Think about it this way: The additional block acts to increase the length of the moment arm. If you have a constant amount of torque as input to the system, and you double the length of the moment arm, you have twice as much force applied to the leafs.

There's only 2 variables in the equation(torque input, and moment arm length). The torque input can be taken as constant, because we're comparing the effects of the blocks, not of an increase in torque. It's exactly what JohnnyU is saying, but without the physics.

As a side note, to Roger - Adding one block of the same height rather than two would not have fixed the problem. There is no less force to deform the spring than there was with two blocks.

I understand that, but stacked blocks is more stupid than tall blocks. The stacked blocks were on the truck when I bought it. As noted, we aren't happy even with the single blocks and will use Tundra leafs under the frame rails. My illustration was to show what can happen with even a 2.3 liter torque monster under the hood.
