That's great news, and I appreciate the heads up. I'm waiting for my Ford Reward points to be credited to pick up a set.

Can you put in 2wd struts to lower the front the same amount ?

 

[AF RET]

I’d love to see some before and after pics of this when someone gets it done…as well as the labor cost if you have someone do the install.

I leveled my 2020 Lariat‎ by lowering rear 2" with shackles from Amazon $36 (‎Psrorkeu - 1"-2" Lift Lowering Rear Drop Leaf Spring Shackle Kit for 2015-2020 Ford F-150)

What is the advantage of this over removing the blocks over the axle?

What is the advantage of this over removing the blocks over the axle?

I was wondering the same thing. Isn't it easier just to pull the blocks out? My understanding from most who posted here is that they just removed the blocks and didn't need to change the shocks, bump stops or mess with the pinion angle. Even the stock U-bolts have enough threads for the nuts to be higher up. The blocks on my '25 RCSB 4X4 look like they are about 1 1/4". I haven't pulled them yet. Still waiting for a consensus.

i just removed the rear blocks on my 21 Platinum PB.. no issues. I run 5100s and also tow. The truck still has a rake, but it looks far better than did stock. I am currently on stock u bolts with some washers, but i also ordered a set of shorter U-bolts have been pretty lazy to get around to it. It's probably been a year since i purchased them.

Before the installation of shackles, it may be required to remove the trailer hitch to access the shackle access the shackle mounts.
1. Jack up the rear of the vehicle using floor jacks, prepare to install both sides at the same time
to avoid binding spring bolts.
2. Support the rear axle with floor jack under the differential.
3. Remove the lower shackle bolts.
4. Jack up the rear end enough to remove the upper shackle bolt.
5. Lightly grease the supplied bushing / sleeves and install the new shackle, with the
6. Install wheels, and lower the vehicle to the ground.
Its best to cycle the suspension and take the vehicle for a drive before observing the amount of drop provided by the aftermarket shackles.
After Installation:
• Check torque on all fasteners for proper torque.
• Readjust headlight settings to account for change in height and angle
• Re‐check torque after 500 miles.

This is a solid ENGINEERED kit with complete instructions, not just shackles. When I installed my 3/5 Kit from IHC, I had constant vibration that took me a while to figure out. I contacted IHC and asked if the transmission required shims to get the driveline angles back into spec. They responded saying the axle perches aligned everything.

I did my own testing and added a 1/2" spacer at the transmission mount similarly designed to the one found on the Ford kit and it solved my issues. It's amazing to see that even a minimal 1.5" rear drop requires a transmission shim, let alone a 5" drop.

Here's a pic of when I picked up my truck, and with the 3/5 drop. I didn't document the shim I made to align the suspension.

That looks badass!

I like those rims.... what are they? Any chance you have a close up pic or side view of your truck handy?

Thanks
