Just wanted to know if anyone knows if it is possible to take 1/2 ton a-arms and use 3/4 ton spindle and/or rotors?Any help would be appreciated.

You can swap the balljoints on the TOP arms, & fit either a 1/2 or 3/4 spindle......the lower arms have a different hole size for the balljoint & need to be changed to fit the balljoint. Are you swapping 3/4 ton parts under your 1/2 ton?

It may be easier to swap the whole front cross member out...but only if the engine is not in it at the time of swapping.

What I am trying to do is lift the truck.I have only found one company that makes lifted a-arms and they are only for the 73-87 1/2 tons.I want to put them on my 3/4 ton.If i cant make the ball joints work with the 3/4 ton spindles is there any way i can make 8 lug rotors work with 1/2 ton spindles...may some wheel bearings from something else.If i cant get this to work i guess im just gonna have to shell out big bucks and have something custom fabricated.Thanks for the info guys.
