DIY rear anti-sway bar upgrade for 2009-2011 Genesis

[scottdk]

I'm interested in this DIY. Do you guys have the Part Number of R-spec Sway Bar?

I don't have a part # but the part is the same on ALL Genesis sedan 2012 models. I actually asked for the part number at one dealer, and they refused to give that information

About 1.5 years ago I ordered the suspension parts on-line from a dealer website to upgrade my 2009 spring/shocks/struts to 2010/2011 specs, and at that time all the part numbers were listed on the website. But I notice now that the same website no longer lists the part numbers.

I would recommend that if someone has a 2009-20011 model and they want a 2012 part, that they get a hold of a 2012 VIN number when ordering the part, to make sure they get the 2012 version. Many times they will want the VIN number to make sure they order the correct replacement part (even if you don't want the "correct" part). Make sure you get the VIN from same model (3.8/4.6) as you have. Some dealer sites list the VIN numbers of their new stock on their websites, or you can just visit a dealer and jot it down.

2012 Genesis Sedan part number for the sway bar #555103M600

Thanks for posting the Part Number.

Last week, I ordered 55510-3M600 online and I'm planning to install it on my 2010 4.6 this weekend after I get rid of the original Dunflops tires.

Quick question, should I get an alignment after installing the rear sway bar?

An alignment is not necessary, and is not affected after replacing a sway bar. You will enjoy the Genesis a lot more once you rid the Dunflops also.

Yesterday, I took half day off and decided to install my new 2012 rear sway bar on my 2010 myself. This way, I could test it with the original dunlops tires which are going to be replaced tomorrow with brand new PZero Nero A/S tires.

The replacement did not go smooth at all and it almost ended being an Epic Failure.

When I removed the original bar, I did notice that the new bar (P/N #55510 3M600) comes with slightly larger brackets. But, I failed to notice that the holes for the bolts on the new bracket are 5mm further apart compared with the ones on the original bar. Because of this difference, it was impossible for me to install all 4 bolts correctly and I ended up damaging the thread in two (one on each side of the car) of those nuts that are soldered to the chassis.

I had to install the original bar back using one bolt on each side and drove "slowly" to a local Indy shop where a Mechanic was able to repair the thread on one nut but the second nut was damaged beyond repair. Then, the Mechanic enlarged the holes on the brackets and replaced the damaged bolt with a longer one that is now connected to a new nut sitting on top of the damaged one.

So far, I haven't noticed a difference between the old bar and the new one.

Sorry for the crappy picture. It was getting dark and my cellphone camera isn't very good. This pic shows the new bracket with larger holes. I took it while the mechanic was away looking for a new longer bolt and nut to replace the damaged ones.

I have modified Hyundai sway bars be replacing the soft OEM bushings with Energy Suspension poly bushings. I did this to my late model 2009 (with factory improved suspension). I noticed a slight but material difference. The car cornered a bit flatter. Ride and bump compliance did not seem all that much different. The harder bushings will transmit more noise, but not a lot. This is a lot cheaper/easier than replacing a sway bar. The hardest part is removing the OEM bushings as they are pressed into place in their brackets.

As for OEM sway bar bushings being too tight, I think that is virtually impossible with the fairly precise fit of bushings to bracket. The bracket tightens metal-to-metal. There is no squishing of the bushing.

Would love to know if you have the diameters of the front and rear sway bars for the 2013 Rspec 5.0 sedan. I'd like to order these sway bar bushings and maybe the link bushings as well from Energy Suspension. They don't list our car specifically

Here is the part. You can order it online at several websites that sell OEM parts for Hyundai (they are Hyundai dealers) or go to a local dealer parts department with the part number:

From the driver seat, I don't notice any difference but, my wife sat on the back seat the other day and said that it feels less bumpy.

 

[shagnat]

LOL....... is your wife accustomed to riding in the back??

After riding in EXBMWGUY's R Spec I think I have been conviced on changing out my suspension for the R Specs. His R Spec felt much more planted.....especially the rear of the car when turning over bumps. Also was pretty noticably more comfortable of a ride.

-Added to my to do list for Spring-

^Was considering the same. Don't want to have the warranty on the suspension voided, but I want a stiffer spring (haven't driven an R-Spec though). Stuck between your R-Spec sway bar idea, or just going all in and getting the Neotech sway bar set.

The R-Spec sway bar is the same as all 2012-2013 Genesis sway bars (including non R-Spec). If you want a stiffer sway bar, you need to get a the one for 4.6 V8 for 2010-2011 models (but I would not recommend that).

If scottdk gets the R-Spec suspension (he already has R-Spec sway bar) he will be getting softer springs, since he has a 2009 (I believe). With slightly softer springs, the shocks and springs will be in better balance, and the shocks will be more effective in keeping the rear end more firmly planted on the road.

I completely replaced my 2009 suspension parts (springs, shocks/struts, and rear anti-sway bar) with 2010/2011 parts, and I am not in the least worried about any warranty issues with the suspension. My 5 year warranty on the suspension will be up in a few moths anyway, but all 5 parts that I replaced only cost about $1050 total (not including installation). If a shock or strut fails, you would probably just want to replace only two of them (in pairs).

I'm not so concerned about my warranty since it's up next January for the bumper to bumper, but getting the R Spec suspension would be a whole new suspension I don't think there is a reason to worry. I wouldn't buy the parts used.

I actually have a 2010 so my sway bar is the 10-11 version, so I'm seeking the R-Spec one. I thought only the 12-12 front sway bars were the same, and that the rear on the R-Spec was slightly larger? (I would just be getting the rear)

I'm not seeking a stiffer sway bar, but I am seeking a stiffer spring, I don't know what I'm going to do just yet though.

My suspension is in decent shape, but I do want to make minor improvements. I look forward to your feedback on the R-Spec suspension.

The new (2012-2013) Rear Stabilizer bar is larger, but now hollow. This allows the rear wheels to act more independently of each other without sacrificing control. The results is that rear wheels should stay planted on the road better than before (unless the road is smooth, in which case no real difference). Someone else on this forum first mentioned that there is only one Rear Stabilizer bar for all trim levels starting in 2012 (3.8 and R-Spec). When I check on www.newhyundaiparts.com I can found the same info since only one Rear Stabilizer bar is listed with the designation of "All" (fits all trim and engine sizes), and that the same bar is used for 2012-2013 model years.

The new rear Stabilizer Bar would probably benefit anyone with a 2009-2011 Genesis.

As you probably know, starting in 2012 the regular Genesis (non R-Spec) got a somewhat softer and more comfortable suspension. However, the R-Spec is still pretty firm like all the 2010-2011 Genesis sedan trim levels. My guess is that the 2012-2013 R-Spec just retained the 2010-2011 springs, shocks/struts, and only replaced the Rear Stabilizer bar to be a bit firmer than 2012-2013 non R-Spec models. If that is the case, replacing the springs, shocks/struts on your 2010 (non R-Spec) with 2012-2013 R-Spec springs, shocks/struts, may make no difference at all.

OTOH, for scottdk, who has a 2009, replacing the springs, shocks/struts (he has already replaced the Rear Stabilizer bar) should yield a noticeable improvement (just as I noticed improvement on my 2009 when I upgraded to 2010/2011 springs, shocks/struts).

If you want a stiffer spring, only option may be one from 2009, but I don't think you can order one from Hyundai anymore. Maybe scottdk will sell you his. However, the 2009 springs overpower the shocks/struts, and the results are not good IMO.

Wow I never considered it might be the same setup. Based on what you're saying I suppose I just want a more planted ride maybe not so much a stiffer spring. I think I'll just try the 12-13 rear sway before I jump to the Neotechs.
