I added the 2" AS Lift about 6 months ago and my 2007 FX4 went up almost 2 3/4". The truck had a 2 1/2" rake from the factory, so I chose the smaller AS lift to try to at least keep it level. After it was on, the front sat just over 1/4" higher in the front. It was not all that noticable, so I decided to live with it for awhile.



After several months, I did not like how the rear sagged even further when I was towing my boat or when I added any kind of weight into the bed. I debated between an 1.5" AAL, a 3" ReadyLift rear block replacement or helper springs. I did not want a harsh ride when the truck was empty, but I felt I needed the extra support when towing my boat in the summer. I read up on the SuperSpring Helpers and they seemed like the perfect solution. For our trucks, I discovered I could get almost an inch of lift by installing them on the higher set of holes. The install was very easy as they simply mounted on top of the existing leaf springs. I was able to do it without taking off the wheels, but I had to lift the truck and use jack stands to remove the tension from the springs.



After buying my new wheels, the rear rake still did not seem like it was quite enough. In this picture, the truck looks almost perfectly level. Plus, with the SuperSpring at their highest setting, the made a lot of noise because the front brackets were tighter and they were rubbing on my leaf springs.



I decided to buy the 3" ReadyLift replacement blocks and lower the SuperSprings down in the front. The rear holes provided the most lift, so I felt it was a good compromise between additional support and a quieter ride.

After installing the ReadyLift blocks last week, I am happy with the final result. The truck has just over a 1" rake measured at the wheel wells and the squeaks are gone. When I loaded it up for a trip over the weekend, the helpers did their job and the truck did not sag.





For those that are interested, here is what the SuperSprings look like installed in the middle position on my truck. The rear is in the higher of the two holes and the front is in the lower of the two holes.

SuperSprings Rear - Higher setting:


SuperSprings Front - Lower setting:


SuperSpring Center - The bracket below the helper spring is to provide a pivot point for trucks that have leaf springs on top of the axle.


The install of the ReadyLift blocks was harder than I expected because I had to remove the brackets for the SuperSpring to replace the factory U-bolts. I also had to remove the wheels and top bolt on the shock to allow me to seperate the leaf springs from the axle with enough room to fit the larger block underneath. The new blocks have the same two holes and pins as the smaller factory blocks, so they fit perfectly without modification. Plus, they have a slight taper to turn the differential upwards.

Here is how the ReadyLift look with their "factory style" bump stops and the new U-Bolts which are included in the package. The u-bolts you see on top of the springs are for the brackets which provide the center pivot point of the SuperSprings.

Let me know if you have any questions.

Truck looks sweet man.

 

Looks Good Man

 

i think im going to put a 3" block on mine.. like you i hate how the rear appears to sag a little bit

 

Great looking truck!! I like a litle rake - your's has a perfect stance now.

 

Sweet! Nice work, let us know if you still experience the sag when towing.

 

Just curious, did you go with the SSA5 or SSA8 springs?

I installed a pair of SSA8.

 

looks killer man

 

Nice looking truck

 

I went with the SSA5 (2000#) because my boat is not very heavy on the hitch. (Less than 500 lbs) I considered the SSA8, but I knew I was going to be asking it to lift my truck slightly and I was trying to keep the ride as smooth as possible.

Did you install yours at the higher settings? If so, did you notice anything different on the ride quality?

Thanks,

I used the lower setting and haven't noticed any difference unloaded. I pull a 22.5' travel trailer and opted for the 3000# (also found a price match and ended up paying the cost of a 2000# pair)

 

I think a slight rake will look good on your truck. I bought ReadyLift blocks at AutoAnthing.com for $130 shipped to my door. They were having a free shipping weekend and I found an online coupon for $9 off of any order over $99.

You will probably have to remove your wheels, unless you have a really big floor jack. I put my jack stands under the truck when the floor jack was at its maximum height and the wheels were touching the ground before I had enough room to insert the new block.

Even after removing the wheel, the factory shock at its full length of travel was keeping the axle from dropping down all the way. Once I removed the top bolt on the shock, the axle dropped another 2 inches or so.

The angle of the axle when doing one side at a time made it difficult to line up the two holes and pins. I had to align the upper part of the block with the underside of the leaf spring and then tap the lower part into the place. Once it all fits together, the block is locked in and looks just like the factory one. I feel very safe with their product under my truck and I recommend the kit for an easy 1" lift in the rear.
