Mine also has the spring pin were my bottom leaf has a pin and the axle has a hole that the pin goes in. Also about the welding i put a 3/4'' inch bead on every side so it would be less likely to come off.

We are talking about a auctul block like you would use in the rear.

 

I'm not trying to be mean or pick on you, but the more you admit the worse it gets.

Quit while you're ahead.

 

I know you weren't I was just trying to justify why I did what I did.

 

i love how when asked to explain the explination is simply a repat of the same unvalidated statement. it is this because its true and thats that like a freakin 4 year old

 

I love how people with 5 posts will just try to puff their chest out and cause problems instead of adding something of value to the conversation.

Pretty sure the explanation has been posted, numerous times. Both sides of the debate have posted good information.

All you're doing is trolling. I really shouldn't feed you, but take this as a polite reminder to not pick fights you won't win.

Cheers

 

For years we've been telling you to stay away from front lift blocks. Not only are they a danger to you, but to everyone around you as well. What makes them so bad? It all boils down to simple physics. Whether driving off-road at high speeds or cruising down the freeway at a normal pace, your vehicle creates a certain amount of rolling momentum. Whenever the brakes are applied, roughly 70 percent of the vehicle's weight is transferred to the front axle. This pitching action causes the front axle to roll forward, thus applying extreme pressure on the front U-bolts and springs. When you add a block into the equation it elevates the leverage point on the front axle, causing the axle roll to become even more dramatic. Enough force or pressure can be applied to fire the front block out from between the axle and the spring. This will result in loss of steering and frontend control, which may have a tragic result for you and the vehicle.

Some argue that welding the front blocks to the axle can eliminate the block from shooting out, and in their mind it's a safe fix. True or not, when you raise the spring perches higher on the axle you place a greater amount of force on the spring. The springs are now working harder to control the vehicle's vertical and lateral movement and can cause the axle to travel unpredictably, cause spring deformation, and also raise the leverage point on the axle. Sure, you won't shoot the block out, but instead the entire axle will wrap violently under the vehicle.




Welding front blocks or building tall perches creates a high leverage point that creates more stress for the leaf spring. This diagram illustrates the forces the vehicle encounters during cornering (shown turning left). The lateral force is now intensified as much of the vehicle's leverage is placed high above the axle. Axlewrap during acceleration is also compounded.






This diagram illustrates the forces the vehicle encounters during braking. The front lift block sits in a high-pressure area and as a result could easily be ejected from between the spring and the axle resulting in complete loss of control over the front end. This only intensifies as tire sizes become larger due to greater leverage.






The only thing worse than having one block in the front is having two! Not only has this truck raised the leverage point by creating a taller perch, but having a loose block resting between the spring and the perch is a recipe for disaster. Seventy percent of your vehicle's braking power comes from the front. Although the blocks here are only a few inches tall, they can easily distort the leaf springs and become deadly projectiles. Another note to mention is welding anything cast is terribly difficult and requires a skilled professional welder to lay a solid bead. So don't do it!

That is much better explained RSWORD

 

There is a Ford in town here that has what looks to be 3" blocks on the front. The best part is that they are painted so you can see what he did! I cringe every time I see it.

 

Im a little lost. 1. I didnt know you could get lift blocks for the front and 2. what makes the front more dangerous to block than the rear? Can someone elaborate?
