who else has heard of this? the physics dont add up. the amount of force/energy it would take to spin a 40lbs ball of lead would rob you of h.p.
if this was for real, arb, detroit locker, etc. would be out of business.
help me with this one.
 
are you asking if they are made of lead? or just add lead to them for additional weight.
 
Adding.

What hp is wasted in spooling it up to rpm, is energy kept when the weight is trying to slow you down
 
Buddy of mine did it years ago. It's basically a cheap non permanent locker.
 
I have a D80 carrier I'm about to post in the classifieds.... its lead filled....came out of a 2nd Gen 24V pulling truck its a OEM LSD that the guy filled full of lead himself. He was running 4 35" tires on the back and the thing pulled great and head up just fine. HEAVY AS HELL THOUGH! LOL
 
jsut dont use the word "competitive" if you have done this. none of the majors offers this as a service. why is that if this "leading" is the same as a locker or spool? nobody competitive is doing this.
 
Im gonna go out on a limb and say someone with an access to cheap or free lead ingots. I could see where it could be less prone to cracking like welded rears sometimes do. But i wouldn't see where that would be an issue on a pulling truck thats always in the dirt.

Im definitely curious about the theory behind it.

Similar to welding the rear, but your also adding support to the housing, lead compresses less than air.
 
So would it be worthwhile to a guy (like me) who has access to a 5 gallon pail of lead wheel weights to do this to a carrier?

Or even weld the spiders then fill it with lead?

Sounds intriguing.....

Yes.
 
Heavier to get moving, but momentum will carry you further, light keeping a heavy rotating assembly. The reason the big guys don't all do it is because they can afford to drop a few grand into the carrier.
 
Wow. You're right about that. I called to see what it's going for now. $0.12/lb. I didn't know it had gone so low. I think it was 3-4 years ago it was really high.

I understood the locking it up portion. But didn't think about the support, lead is pretty soft, will it really offer any substantial support?

I did think about the inertia factor. But was thinking it could hinder getting going on real tight track.

Try to compress it. Not deform it, but compressing it, and it being contained in the same volume. Not saying offers lots of support. Really it is along the same lines of locking it up. If it has enuff support to lock it up, surely enough support to minimize deflection.
 
Wheel weights are not lead .. they are a zinc alloy now, and for the last few years, heck its illegal to sell lead wheelweights ata tire store in nys .. lol enviro commies. The older wheelweights had lead but the alloy sucked for melting down etc..melting a can of old wheel weights might not get the best results.. the old body shop lead or battery lead may be better. sounds like a decent way to geta locked rear on the cheap, bush pull style.

Gotcha
 
the lead adds constant resistance. drag. and the whole inertia and momentum thing is good on zero resistance. but we have resistance. the weight is the killer of this whole concept.
