Product Works Good, Support not good.

They work OK. The problem I had was that one of the bushings was the wrong size. I tried to get that replaced by Lippert and they just sent the wrong one twice. Amazon was no help either. I "sanded" down one of the wrong bushings to make it fit. Again, once installed, they work good. My issue is product support. I wonder how good the "lifetime" warranty is?

Big Improvement in Trailer Ride, but Big Installation Job for this DIY'er
CharlieR✓ Verified Purchase•September 16, 2016
I installed the 4k-6k Equa-flex along with the MorRyde Wet Bolt Shackle Upgrade kit on my Outback 27RLS travel trailer (8K GVWR). This was the proper kit for my tandem axles, each having a weight rating of 5K. Now that it is complete, I am happy with the ride improvement of the trailer, which is much improved over the standard suspension with just a straight equalizer.
I did the installation myself in my driveway, doing one side at a time, using two jackstands, a bottle jack for jacking the frame to place the stands, and two bottle jacks for the axles. Installation was a fairly big job, but the hardest part was not getting the old bolts and nuts off; it was setting the last bolt to attach the second leaf spring to the Equa-flex equalizer arm. I used PB Blaster to soak the old nuts overnight, then used an electric impact wrench which made short work of the rusty nuts, so removal of old hardware was pretty easy. Likewise, getting the new bronze bushings and new bolts in was pretty easy except for the final bolt. The problem is that the spring eyes don't match up perfectly with the Equa-Flex if you are replacing the standard 13-104 equalizer and keeping the same shackle length. The directions don't tell you this, and make it seem like the installation is very straightforward. I had to use a crowbar, a prybar, and a couple of wooden blocks to deflect the springs enough to get that last bolt in. No amount of axle jacking would result in the right amount of deflection and height to get the last spring eye to line up with the Equa-flex arm. I really wish the directions would have been more detailed and hadn't left it to me to figure out how to make the installation work. In the end, however, I did it and am happy with the final result.
