39 spindles with 4 inch drop axel

Hi iam looking at fitting a 4 inch drop axel to my 30 a ccpu and was thinking of useing 39 spindles as I am running 39 brakes to get the steering away from the chassis. Dose anyone see a problem with wanting to fit those.

 

That's a pretty normal combo. You can use any 37 to 48 spindles with that set up. 37 to 41 being the round back spindles and 42 to 48 being the squared off ones.

 

If you run wishbones you will need to drop the steering arms or cut the steering arms off and run bolt on dropped steering arms.. If you run hairpins or 4 bars you will be fine with the stock spindles...

 

That sounds good thanks. I plan on running hairpins so that will work fine.

 

Are you sure about that? I had to heat and bend my arms. I don't see how hairpins would help.

4 inch dropped A axle. 39 round back spindles.

 

Concur with Hitchhiker. I had to bend my steering arms on a 40 with a 4 inch drop or the arms hit the axle.

 

I think it depends on your set up, but just about all the time with a dropped axle you'll have to run dropped Spindles. You may be able to run a tie rod through haipins without dropped arms but you'll have to check frame clearance.

 

I've got 39 spindles on a 4" dropped A, no problems. I'm running 36-40 style radius rods. This required some grinding to get them to fit, but the tie rod runs under them with no interference so no need to bend the arms.

 

Hang your spindles on the axle and you will know.

 

when you turn wheels both ways and steering arms hit axle, you will realize its time for HEAT.. It Has little to do with four bar, or radius rods, if it hits axle first, aaah, yes, THEN comes time to fit tie rod...

you speak of getting steering AWAY from chassis,,, ??? 's'plain

 

If you run a So-Cal 4 inch forged dropped axle with hairpins and stock 37-40 spindles no heating and bending of the steering arms is necessary and they will turn lock to lock. Done it dozens of times.

 

If you decide to run bolt on arms, please find some spindles that are already missing the arms. Don't cut the arms off...please.

 

Never had a problem on model A's with hairpins and 37-48 spindles.. The tie rod ran right through the middle..

 

But what about the steering arm hitting the dropped axle when turning? That's the problem I was seeing. You still have to heat and move them down a bit so the spindle arms clear the axle when turning.

 

If you run a So-Cal it may clear and if you don't it may not clear. Just be ready and move on.

 

I've never had to bend anything.. Backing plates hits the stops as they should.. Also depends on which dropped axle you use.. I've always used aftermarket and have not had a problem...
