I have a 2007 F150 4X4 Shortbox Regular Cab with a 2" Front Autospring lift and a 3" replacement block kit in the rear. The Autospring website says that the 3" rear spacer replaces the factory 1 5/8" block so it seems to me the rear is effectively about 1 3/8" higher than stock.
I want to put new shocks on the truck all the way around. Do I need special length rear shocks now, or can I go with a direct standard length replacement?
Thanks.

 

Replacement shocks that are designed for a 1-2 inch lift will be required. since you changed the ride height of the truck you change the travel distance of the shock. indoing so you counld easily fully extend the shock before the suspension completed it travel. When loading the shock, since you are starting at a partial extension, it will not absorb the load properly. could give you a bad ride, soft/bouncy. Recommend replacement with kyb monomax 2 inch lift replacement shocks.

 

OK. Thanks.

 

I just checked the KYB site. They don't make these shoks for my truck.

 

Check out, Fabtech, rancho, sky jacker or possibly bilstein. Look for 2 inch lift kits, then parts listing for shock part #'s. might have to call to get price and shipping.

 

you do not need longer shocks


at full extension, the shock will NOT be limiting axle travel. the shock length is more than sufficient for an extra 1.5" of lenght.


many many people are running that 3" block and have zero issues. call up Autosprings and ask them. I bet they tell you the same thing. or you can unbolt the lower portion of the shock and let it hang down. then jack the truck up until the axle is at full droop (use frame for jacking). compare where the shock lower eye sits versus it's place on the axle.



btw, Bilstien shocks are pretty much considered the best shocks for the 2004+ F-150. You will find people here and on many other forums who swear by them...and the pricing isn't bad either

 

I contacted Autospring. They reccomend a 2" lift shock from Rancho or Bilstein.

 

Cool man, just because other people are still using stock shocks and having no problems with it, doesn't mean that you won't. Plus, there is the right way and the wrong way to doing stuff. With recommendations from the manufacture as well, i would start pricing the shocks out and deciding which ones to go with. If possible, bilstiens are some of the best made in the world.

 

Get the Bilstein shock, man has it made a difference in ride and handling on my 05 ext cab 4x4 f150. If you get the standard shock they make its a much better shock than most others out there.
