Stronger rear springs!

Were on our 3rd Santa Fe (09, 13, 17). All have been 3rd row/LWB variants. With each one ive noticed the rear suspension lacks when it comes to aupporting any sort of load. Were not talking about overloading here either. Just Filling the car with the amount of people its advertised to handle.

Ive only come across 2 solutions. Firestone airbags, and sumo springs/coil spring spacers. Neither really excited me.

I researched, compared, emailed and came up with what seems a legitimate solution. Hyundai Veracruz rear springs! Per Hyundai specs, the comparable springs (AWD model) were around 0.5 inches taller. The GVWR for the veracruz is about 500 lbs more so common sense tells me the springs would be stiffer, albeit slightly.

I emailed Hyundai. After 3 weeks of no response i called and was told to contact my local dealer for spring rate info. Yeah. I work for the local dealer . Hyundai doesnt publish speing rates.

So i pulled the trigger, and figured at worst i gotta eat the restock fee.

They work. Pictures to follow shortly.

There is a definate improvement in how it rides, and currently it sits 1.5 inches higher in the rear. I do expect it to settle in at around an inch over stock. More reviews to come once we get it loaded up a bit. I dont expect it to be perfect, but its gotta be better.

The part number I obtained is 55330-3J010

How is the ride now?
I find there is a lot of bounce in the back, speed bumps are the obvious test. I would be interested in reducing the bump for that alone !

Its nothing short of amazing. I expected a little harshness over the bumps/rough stuff, but its not at all.

The bounce is VERY minimal and overall road manners are improved. The car feels much more planted and balanced in corners.

Simply put, this is how Hyundai should have set this up from the factory.

Additionally. I did swap out the factory kumhos for Michelin defender LTX. Obviously some of the improvement is a result of the tires, but the greater difference comes from the springs.

Whats the cost of these springs? (any idea on installation costs?)
I am very tempted to do this too.
I have knocked those mini mudflaps loose several times going over speed bumps. The back feels like it bounces excessively every time. Stiffening this would make a huge difference.

Hyundai oem parts (dot) com has the springs at a few cents under $80 each. Lets go with some rough estimates.

$200 for springs (s&h, $40 would be absurd, but its easy math)

Its pretty simple to do. A high end labor estimate would be 1.5 hours (realistically im thinking 0.8 total, but i dont have that info available at this time) x$100.00 per labor hour puts you at $150. (100 / hr is an average and dependant upon your area)

So were at $350 and you WILL need an alignment with these. Pick the highest priced alignment im aware of $150.

All in, $500 should be the highest you could pay to have this done in a shop.

Id bet you get probably get it down significantly, maybe in the $250-$350 range.

Knowing how it rides now, i'd pay that $500 if you told me thats how much a permanent, and legitimate solution costs. I like it that much. (Its the wifes car, and she usually doesnt notice when i do anything outside of fill the fuel tank or wash the car...she loves it!)
Way-pointer and cochino like this.
