I have a 1978 F150 4x4 short stepside. It seems to be lifted but I can’t tell if this is OEM stuff or not. This block is about 3”. There doesn’t seem to be any kind of lift in the front.
thx
Yes that is an OEM block and X2 yes from an older truck, since it has the u bolt eye lets. The wing is for your overload bumper to contact. Are you running 31's, 33's, 35's? And what is your rear leaf spring leaf count? Damn nice truck. The last pic is a stock OEM block on a 79 F250. With rear Superlift 6" leaf springs and a pinion angle shim.

My truck rear leaf springs have 5 leaves and I’m running 32-11.50x15s. Is that what should have come on this truck originally? So you are saying yes, OEM, but not original to this 1978 truck, right? Originally, was there a different block there or none at all? Thx

Interesting would my 74 have had the u bolt eyelets? I always thought it looked like my blocks had something broken but I chocked it up to being old and probably was just scars from casting.

5 leafs sound stock, 32's fitting on a stock 4wd truck sounds right. Maybe 78 4wd 1/2 tons came with that block that has the u bolt eyelets? I do not know. My 79 4wd F250 did not come with them.
Maybe on your truck it originally had a shorter OEM block, and your trucks PO got a taller one to give it a bit of rear lift? And yes I am pretty sure that all 73-79 2wd and 4wd trucks came with a block of some sort back there. 78/79 Bronco more like a shim.
Thanks for posting. According to the diagram the stock block on all the 73-79 4x4s has the eyes/guides for the u bolts. I betting is is pretty much the way it left the factory. Thx
Well the top diagram has 73/ F100/F150-- 4/W/D so who knows if it goes all the way to 79? But I know for sure the blocks on the rear of my 79 F250 4wd are stock and do not have the eyelets.
Maybe ND will post a rear suspension diagram for a 79.

Well if it's not absolutely necessary I probably won't go hunting for some with eyelets. I'm sure when the PO swapped out the rear axle he cut them off for the larger u bolts in the back.
Blocks are nothing but a fulcrum for axle wrap/hop IMO. Let me insert (at least stacked blocks) are. The ig-no-ray-moose PO of ol blue just cut off the overload ear on a set and double stacked them. 460, some clutch and excess gas and that thing power hops like crazy and makes the u joints scream.
My plan one day is to delete the rear block all together and not just by buying some Atlas Suspension leafs either. The red truck gets along just fine without the eyelets and had not spit a block out yet. With proper torque of the u bolts I am sure the none eyelet block is just fine.
My 78 has those blocks and 5 leafs. I have 15/12.5 /35
they fit no problem. I think the front coils springs have been replaced because they were red.
🤔
Big Craig appreciate the help, as always check your beer born on date and check the thread last post date......06/06/2019 I am sure the guy has it under control by now. But no worries about it, we all do or have done it.
