these 3rd party blocks don’t have tabs and guide holes so they move.

 

Ready lift makes their rear lift blocks in one piece and have the factory bump stop arms on them. I’m sure several other manufactures do as well.

 

Hello Morph35,
We are also new members to this awesome forum and are the importers of a High Quality Extreme Performance line of shocks, please take a moment to look at ALKOSHOCKS.COM, in the search box type in "2 Rear HD Performance Shocks for 99-15 Ford F-250 / F-350 4WD with 0"-2.5 "Lift" we have had very good results and feedback on these and by the sounds of things these would be great for your truck! Part number #813021 is 30.53" extended and 18.5" compressed, they have a 70mm Big Bore body with a 20mm Piston Rod which offer great ride and performance at really affordable prices.
Thanks,
Dennis

 

Is that extra block for a 2.5" wide spring? Everything's starting to shift, those blocks are going to get spit out and cause major carnage. Get the right one piece block or get full springs . And NEW u bolts.
