Anyone hear anything good or bad about Clevis/ front strut extension lift? It is the Protune Suspension Steel Lift Kit | Front 3.5" Rear 2" | Grand Cherokee WK Commander XK. I have a 3" OME that I may add this to. Any thoughts good or bad? Seems less work than cheap metal top strut spacer but is it much less strong????

$150 for front and back spacers. rear is like metal Rough Country but front is extended/reenforced clevis ..... hmmmm? Think much less time and effort than top 2" regular spacer as with other products we are more use to. Looks like an hour Job, so 3.5 for me.

How far off the ground are your front wheel wells? Mine are 37.5 with ome and Bilstein 5100s. This gives me about 1.5 in downward travel.... Very little. I don't think you will be able to get the extended fork in there and bolt everything up ... And If somehow you do, there will be terrible stress on the front driveline and absolutely no downward travel... It will definitely look really cool though.

Thx



That's great info. I'll do the measuring then. If it all adds up do u think it would be less work than the Rough Country Hockey puck style spacer to add a little or is it the same work? Just mentioning I have the Hemi because things are so tight in there every time I need to work on something and many of the plastic parts are now brittle w electric housing, clips etc in my 2006. Not sure if that's another issue or better off not touching. Was thinking about cooler, possibly even 180 thermostat if someone recommends or even putting in vents in hood at this point. ugg Thanks everyone!

Lower thermostats will not increase the cooling capacity of any vehicle. Thats an old school hot rodder deal. Modern electronically controlled engines are designed to work most efficiently in a certain temperature range.

Do you have cooling problems?

I forget what years have a mech fan (i think 2006 does) but you could swap to high quality electric fans, maybe OEM(not the cheapo bright red chinesium ones the tuners use) That frees up power and can increase cooling capacity when paired with a proper shroud.

Radiators can be upgraded certainly, but again dont fall into the trap of getting a cheapo "performance" rad from ebay or something. You'll likely be hurting rather then helping.

These have been around for awhile. Heavy Metal is the first brand I remember seeing on EBAY.

Generally they are overrating their lift numbers. Actual ride height increase is around 1.5" to 2" (from stock height) in the front IIRC, and 1.5" in the rear. They add those numbers together and that is where they get "3.5" lift"

This is probably a good option for someone with issues with their clevis and clevis bolt since it is usually hard to find a stock replacement clevis. AFAIK there is no strength increase, probably weaker then stock just looking at them, but I have not heard of anyone breaking them.

As someone that has torn down the front end twice Im not sure how this is any easier then a RC style lift. Same degree of difficulty IMHO.

This is true, but it gives some reference, and there is no line in the center of the hub. I'm running 265/70/17... So roughly a 32 / 2 =16 or 21.5 using center of hub.

Just to add a little bit to this conversation... If you're at 20.5 in the front then you probably have the MD OME springs - they won't lift as much as the HD. I have the OME's HD springs on my Hemi and I'm a tick under 22" in front which is plenty high.

As has been said already, with the independent front suspension design of the XK/WK the issue becomes the CV axles the higher you go. They get to the point where they're pulling out of the front diff and/or binding as you turn and when the a front corner needs to droop. Best to go with a SuperLift as mentioned above if you really want to lift your XK above 22 inches. Most of the lifted pickups you see running around these days have a variation of the SuperLift on them to prevent front CV axle issues. If you look at them closely you'll see the CV's are basically level with the ground even though it takes a step ladder to get in the cab - that's because the entire front suspension has been dropped to create the lift.

With your setup a spacer on top of the coilover assembly - or Bilstein 5100 adjustable shocks - will do the trick. Just don't go over 22 inches from the center of the hub to the fender flare and you'll avoid the UCA hitting the springs, you'll save your CV's and the alignment shop won't shut its doors when they see you coming since you'll be able to get alignment within stock specs.
