Nice bushings.  But I found out the Z06 doesn't use them.  So now I have 4 bushings.

Make sure you get the right size.  Measure your Swaybar diameter.  My 2004 has a 27mm bar and should have had Part #80819.  #80818 listed for a 2WD, which did not exist that I know of.  Otherwise the bushing is of good quality and fits well.

Works great. Watch the guide bushing depth since they are not all the same. Make your guide or template the correct thickness to extend past the bushing.

Once your rubber bushings start to fail or its time for your 90k service you might as well swap out some of the oem parts. I did exactly that. Really tightened up the front end.

I received the set and started checking the directions and the part numbers on the bushings. for the lca bushings you are supposed to receive 4 of part #2274. in the package are 4 of part #2272(supposed to be in 16.8102g) which i bought to compliment this kit. I am glad i read through the directions and checked these before i started replacing them. I will not complain as long as the problem is fixed fast. Mistakes happen. I did attempt to contact energy suspension but they are closed due to the holiday.

So far this bushing is doing its job. The OEM bushing I had installed lasted for about 3 days out in Moab, UT.  The rubber in the OEM bushing worked its way out of the shell. The additional stiffness of this poly bushing will hopefully eliminate this issue.

One issue with these is the fact that no outer steel shell is provided. Thankfully they make no secret about this at at the same time I'm not sure why they don't include one. In my case, and in most others I would guess, I couldn't get the original shell out of the axle without wrecking it. That meant that in addition to these bushings, I had to buy another set of OEM bushings just the use their shells. In addition, getting the rubber out of the OEM shells is no picnic. I wound up making an insert that fit just inside the original shell and pressing the rubber out. It worked well but without a lathe to make the bushing I'd have been drilling the rubber out which would have been a horrible mess and no fun to boot.

Once I had a clean undamaged shell installation was a breeze so providing the shell would make these bushing an easy 5 stars. Without them though I'm going to have to drop a star. Also, if these bushings fail prematurely I will update this review.

I really wish this would have fit my vehicle because it looked to be well built and the "corkscrew" design works great for reducing the "whistling" sound when driving at high speeds.  The product description and Amazon "make sure it fits" application both said this would fit my 2006 GMC Sierra 2500HD, but when the antenna arrived the male thread on my truck was much larger than the female threaded base of the antenna.  After doing further research, I believe this antenna has a M6 thread and my 2006 Sierra has a M7 thread post. I'm guessing there was a transition to the larger M7 fitting sometime in 2006.  I ended up buying a universal antenna and it came with adapters to fit most models.  The universal antenna looks OK, but is very noisy at speeds over 45MPH and I would have liked to have the ACDelco model. There is an adapter for sale separately that will reduce an M7 thread to an M6 but it is sold separately.  Amazon receives 2 star for not having the right vehicle info and 5 stars for a no hassle return.

Worked great for my C6 Z06. Use all the new parts that are included in the package. Don't bother trying to reuse any of the old parts because they won't fit.

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?

Would have worked but I have a rare option on my IROC. It has a rear wiper motor and it got in the way when I tried to install it. I tried to send it back but I never got a refund for it (yet) and I hope I will get one (soon I hope). Other than that. It is a very well built box and would have worked with my 1985 IROC/z28 without a problem. It doesn't sit flat in the tub so that is why it was a problem. It slants up and it sits on the flat parts inside the tub itself. Nothing I could do. I need to buy another one that lays flat (dang it!). Customer service was good but I don't know how long it takes to get a refund. I will post once I receive it.

I really like the design of this one compared to similar brands they carry at the local hardware store.  The plastic seems much stronger and the twist-to-load design is better.

The problem for me is that it didn't fit my Craftsman brand trimmer, which has a 10mm x 1.0mm LH male stud.  This trimmer does come with a bushing for it, but for some reason, the bushing for this size is threaded only half way.  If it were threaded the all the way through, like the other 2 included bushings, it would have worked.  Looking into it further, it looks like it comes with the same bushings as some ECHO trimmer heads, so maybe it needs to be that way to adapt to another brand.  I was disappointed since it doesn't fit all models, so I knocked a star off and am returning it.

So for parts reference, it comes with 2 bushings that are threaded all the way, 10 x 1.25 and 8 x 1.25 which will work for male studs, and one threaded half way (furthest from the mounting point) that is 10 x 1.0.  It also includes 2 male studs for female sockets, in sizes 7 x 1.0 and 8 x 1.25.  Since it is for straight shaft, they are all LH threaded, which means its opposite, left is tight, right is loosen.

Fit my 06 ZX3 despite some sights not including my year model in the application guide.
This is the forward most bushing on the rear trailing arm. It's the main pivot on the chassis and a fairly large bushing. As pictured it came with plenty of grease.

My brother and I fought with the old, rubber, bonded bushing that was in the trailing arm for a while. Trying to cut it out, was slow and we didn't want to damage the  housing or the pin that goes through the bushing.
Eventually we just hit it with a torch and burned it out; which worked great!

Results: Its hard to notice a difference but those particular bushings were not bad on my car. Although, I do know that when put under excessive weight, the OEM rubber tends to give a lot, which will through your alignment off. Theoretically, the polyurethane will help with this.

Everything fit pretty well, except I had to use the rubber bushing from my old set as it wouldn't fit in the new one.

I never knew that bushings made such a differance with the ride. I installed Moog on the front, so why not the rear the, the mattrial seems to be tops. The blue looks great also,By the way my jeep is a 97" grand cherokee TSI, don't know if this has anything to do with the size of the sway bars Thank' Dan.

What I liked-the color.

What i didn't like-the bushings/washers that come with the shocks.  They seem to be small in size and girth compared to the OEM's.  Does that mean anything?  I'm not sure but when you are a DIY'r in the middle of a shock job, you want everything to look the way it should.

The other thing is that the "Does fit your car tool should be upgraded to account for the vehicles that have more than a standard suspension on them.  I nearly bought the wrong back shocks just because the functionality of it will fit said the shocks would fit.  The new shocks seemed to be about an inch shorter but stiffer then the ones I replaced.  That makes sense.

What I did like was that I got the shocks faster than I was prepared to actually install them.  NICE.  We'll see if the DW says anything about the ride before I spring her about the cost of the Nivomat shocks that are going to be replaced next for the rear.

the large end bushing was 5/8" longer than the existing one forcing mw to return it as it did not fit the 2007 Mazda 6i it was purchased for.

The bolts worked great but unfortunately I was not aware that I needed to purchase a nut and bushings for the lock pins.
