Had to press out the threaded eye on one spring. The shackle wouldn't screw in. Pressed in the one that came with the original replacement shackle. Rear sleeve was to loose so I replaced it with the Poises 457 sleeve. Haven't run truck yet.

I love the height of the super slide springs. Got the front done, now going to do the rear in the near future. Much improved ride, even with just the front installed. I'm no mechanic, but I got these installed with no issues. Love them.

Nice springs. Easy install. Fit perfectly.

Only cons are your steering wheel will need to be recentered and you will have to press out the threaded bushings in the new springs if you want to use the shackles with rubber bushings that come in the kit. Also you may need to replace front shocks with a shorter stroke set.
