I would exercise caution if you are looking at using the KLC166 HD rear end links.

I've had a set fail on me due to the way it is constructed.
On the part that sits in the lower control arm, there isn't sufficient distance for the nut to clear the weld, causing it to mount on the angle, placing stress on the weld and causing it to fracture and fail.
It also takes a few chunks out of the rear sway bar when it does this!

It is also not as wide as the OEM link, causing the lower control arm to bend inwards as we found out when mine were replaced due to the broken rear end link.

Will try and find some photos if I still have some.

Also have the front HD end links and haven't had any issues with these at all.
