I have a 76 F150 4x4. It has what appears to be a factory lift kit. The blocks on the rear springs are anvil shaped and 3 1/2" tall. I am guessing I will need the 4 degree replacement c-bushings? Any confirmation would be greatly appreciated.

 

Stop.

The rear blocks are OEM and at OEM height if there are no other blocks and OEM leaf packs.

The degreed C-bushings are for the front when there is a lift installed over and above the OEM height.

Do you know if you have more lift than OEM??? A 4-degree C-bushing is for a 2- to 4-inch lift. From your description of the OEM rear blocks, I assume that the front is not lifted at all and thus does not require any corrected C-bushings to restore lost caster when it is lifted.

 

Correct nothing but the rear blocks. Looks like that would be the 2 degree then. Much thanks

 

Like HIO said,
"The degreed C-bushings are for the front when there is a lift installed over and above the OEM height."

If the blocks in the rear are stock you do not need degree c-bushings

 

Thanks again Guys. That's why I asked first. I really appreciate the help.

 

Are you positive there is a rear lift?

 

I'm not positive. Only thing it has is the 3 1/2" anvil blocks in the rear. No other blocks front or back and no added leaves. I assumed the blocks in back meant it had a lift. Maybe that is stock as in no lift for these trucks. Looks like HIO is saying that is considered no lift for these trucks. The 2 degree bushings state for no lift up to 2" inch lift so looks like those will be the ones I am getting.

 

That is correct. Just the anvil blocks means there is no lift.

Yep. I recall someone out there lists a 0-2"-lift C-bushings.

 

HIO said it all.
