I'm looking at putting together a lift for my 79 bronco, with the shackle flip in the rear and a pair of 6" lift coils in the front.

This leads me to my question, do I need to drop the radius arm bracket or put a degreed C bushing in the front to compensate for my new angles?

Are there advantages to one over the other.?

This is a 79 Bronco with 429. Will I be able to use stock lift coils, or do I have to specify that there is a BBF under the hood?

Thanks

85 people looked at this, and no one knows if you have to put a degree'd C bushing on the radius arm.

By my understanding, you put in the bushing on the diff/arm side if you are not planning on putting a drop on the radius arm/frame side.

If you don't want to install the drop brackets, then you're going to need to install the degreed bushings. And you don't need to mention anything about the engine, since the BBF is only about 100lbs heavier than the stock engine

Thanks for the reply, is one better than the other?

Are you going to be wheeling, or are you looking for the cheapest route????

I think the bushing are half as much as drop brackets.

You will need the degreed C bushings at the axle either way. With 6in of lift you will need to point the pinion up towards the transfer case to relieve the angle of the front driveshaft. I believe i used 3in drop brackets and 7 degree bushings on my 79 f150.

To be picky, it is not to point the pinion up at the transfer case and relieve the angle. (unless you have a CV/double cardan), look up the drive-line tech info about pinion/driveline angles if you don't believe me.

Anyways even using the aftermarket poly bushings are a step up from the stock rubber ones, a tiny bit less flexy, but they poly's have extra material that wraps around the radius arms to keep from squishing out from around the axle.

the bushings are for caster...not pinion angle

I'm with Dc. The degree'd c bushings are for caster correction of the axle.
