Anyone install rear blocks? What did you use? There doesn't seem to be many options out there yet.

Rough Country has them but also come with the front spacers, but I just installed spacers today.

The 2021 FX4 rear block setup is different than the 17 Lariat. The U bolt is more round on the 21 as opposed to square on the 17. So they aren't interchangeable.

I just got my order of 2.5" rear replacement blocks from Stage 3 motorsports. Stock blocks are 1 1/4-1"1/2 tall on my CC 4x4 NON FX4 with Max tow. I have a 2.5" level and want a little rake for towing. It should lift the rear 1" supposedly. The kit I bought was Eibach 2.5" rear blocks and it said it fit the 21's. It came with new U-bolts but I haven't installed. I'll let you know it will probolly be next week.

Oh awesome, would you send me a pic of the parts?

In the 17 we had 3" F&R and it was good, slight rake. After installing just the front on the 21, the front definitely is too high lol. So looking for 2.5 or 3" rear block.

I did the ones that come in the Rough Country kit today. Didn’t run into any issues other than have to remove the arm for the headlights prior to removing the existing u-bolts. I don’t prefer to stack blocks, but it was cheap.

What did the U bolts look like? I had Rough Country in the 17 and they definitely did not work in the 21

They were more round like they should be for the 21’s.

Anyone try and remove the 1 inch stock block to drop the rear one inch yet?

Great, so you ordered this kit, and stacked the rear blocks for like 3 1/4, in the rear?

You got it, 57100 is correct. I ordered mine from Truckspring.com. I wanted to maintain some rake. My Readylift kit up front is going in next Friday.

A couple quick pictures of the blocks installed. I'll grab a side shot once the level is on. I'll be running stock wheels and tires with the level for a couple weeks before the Fuel's arrive.

If you haven't already, do some homework on stacking rear blocks guys and then decide if stacking is the route you want to pursue.

If you have & you're cool with it, more power to ya' ?

Or how about enlightening the group with some education? I see all sorts of stories about guys that stack blocks on lift kits and then go hard off road and are disappointed. Having 6" of homemade blocks stacked is considerably different. Show me where under normal conditions that a 1" block, with dual locating pins, is unsafe. When someone else releases a compatible single block that isn't outrageously priced, I'll probably go that direction, but I don't anticipate having any issues in the interim.
