80-04 Ford F-250/350 4x4 5" & 6" Rear Block/Ubolt Kits.

Very impressed with the 6” blocks for my 04 F350. There were some cons though. The carrier bearing needed to be dropped 3/4” to stop the driveline vibration. And the U bolts that came with the blocks were too short. They do work but I prefer 6 threads to be proud of the nylock nut. These are flush on one side. Not a big deal, I’ll get some new U bolts made as I waited over a year to install the blocks. Otherwise, outstanding set of blocks.

I've been wanting to buy these blocks for over a year. I finally pulled the trigger and these blocks are great! I replaced some 5.5" lift blocks that came with my truck. One of them was twisted and I could certainly feel a lot of axle wrap with a heavy load. I hit the Sky's blocks with a 3m scuff pad, cleaned with acetone, and painted them black with rustoleum. They came out really nice. The U-Bolts were already painted up. Install was a breeze. A little trick is to lift the front of the differential with a jack to align the pins and holes. These blocks aren't going anywhere with the built in U-Bolt retainers. Also it's great to have bump stops. Thanks for a great product Sky's!

Was truly amazed at the build quality and ease of installation. Brackets went in with little to no mods and bolted right up. Much better alternative to the stacked block assembly.

Thanks!

I received the 6" Ford rear lift blocks today. You've succeeded where many have failed. You've impressed me. Nice work. A breath of fresh air in the aftermarket community. The person who welded these up is an artist amongst his trade. If you ever let him go, send him my way; I'll hire him.

Not sure how you're making any money off of these. With all that went into manufacturing these blocks, I'd be hard pressed to make them any cheaper myself. Glad I didn't try. Yours turned out perfect.

Very much appreciated

Love the blocks! Replaced a stacked lift block set with these, and they fit like a dream. The design really works well
