VVK's premier product for the R230 Mercedes. Made in the USA from precision machined parts and built to last. 

Mercedes Active Body Control system (ABC) often becomes a constant maintenance issue, frequently costing thousands with each repair. The VVK coilover kit completely eliminates ABC, for good. This kit includes everything to safely and securely replace your entire ABC system with a coilover suspension (like the SL65 Black Series), not only getting rid of your headaches, but also giving you the confident handling & control your SL deserves.

This kit includes the following:

  • Full Coilover Suspension (32-click simultaneous compression & rebound adjustment on top of each strut)             
  • Replacement Power Steering Pump (Eliminates the stock dual pump which feeds ABC)
  • Custom sport VVK Front and Rear Sway Bars (2-position Adjustable Front) . (These are NOT the small Original Mercedes bars designed for the lighter V6 SL350). 
  • All Required Hardware for Complete Install
  • 1-Year Limited Warranty on Manufacturing Defects       

Damper Dyno Charts

VVK’s coilover conversion for the R230 chassis has been engineered with precision, and our dyno charts for both the front and rear dampers below showcase the exceptional quality of our adjustable dampers. Our results prove the smooth, predictable, and balanced adjustment range of our dampers, ensuring a top-tier suspension upgrade.

The compression damping (top lines) in both the front and rear dyno charts displays a smooth, linear progression with each click, delivering predictable increases in force. This ensures controlled chassis stability, improved front-end grip under braking, and enhanced rear traction during acceleration. The rebound damping (bottom lines) is evenly spaced, demonstrating precise control over weight transfer, ensuring maximum tire contact and consistent handling performance. With each adjustment click affecting both compression and rebound simultaneously, our dampers provide harmonized tuning for road and track use.

At VVK, we proudly present our results because we know our product delivers consistent and precise performance. Our dampers are engineered for reliability and superior handling, ensuring that every adjustment translates into meaningful improvements on the road or track.


This kit is available in two options: Street and Race

The Street version gives you the everyday Grand Touring car your SL was designed to be. With a wide range of adjustable valving you can easily set the car to match your driving style and needs, truly transforming your SL. Dial in softer damping for smooth cruising or turn it up to remind you what the SL can really do.

The Race version goes a step further and increases the spring rates and valving. Especially suitable for aggressive canyon carving, track days and also great for widebody or extra low cars. The fine tuned spring/damper combination really lends a race tuned feel. For those with big HP, this kit will provide the handling confidence to really push your car at the track.

NOTE: New engine mounts are a MUST, (we recommend Mercedes black series part number 2402400817 for better sway bar clearance, performance and durability, especially for cars over 350hp). We have seen 35,000mile cars with original mounts collapsed simply due to age. The sway bar will contact oil pan if mounts are collapsed. 

 ☆ Please allow 2week lead time for each kit hand assembled here in Florida.☆   

 ☆ All cancellations subject to 3.9% processing fee, returns will be subject to 15% restocking fee.☆

Awesome for hyper dogs
Color: Blue
AWESOME - I have a dog that just won't stop trying to get me to play with him ALL day! I turn this thing on and he goes nuts and tires himself out...without any help from me. The cover got torn off and torn up in minutes but he doesn't care. He just wants this ball. My other dogs, who are older, aren't really interested. But if you have a hyper dog this is the thing for you and them!

Great entertainment, charges quickly!
Color: Orange
Super fun entertainment for dog! Toy ball charges quickly and the charge lasts for at least an hour of playtime for the dog. There are 2 modes. one mode Just lights up, which makes it easy for pet to chase it. The second mode not only lights up, but it also wiggles on the ground Randomly and speeds off in a direction on its own, which really makes it interesting for your dog or cat to follow! Once the ball is not touched for about thirty seconds, it goes dormant and it will stay like that As long as it's charged until somebody touches it, and then it starts up randomly lighting up and moving around the floor on its own And making a vibration noise. It's a lot of fun to watch the dog chase and play with, and it certainly keeps them entertained for a while! The laughs and fun entertainment are definitely worth it. The only downside is that my dog chewed off the soft fabric covering in about twenty minutes.And she's not a real big chewer. It looks better with the covering on it, but even without it, the ball works fine and she plays with it every day.So that is not a showstopper. But good to supervise your dog for safety.In case they are a chewer, and they decide to destroy the cover. But the ball works fine without the cover too!

Looooves her crazy new ball
Color: Orange, Color: Orange
Our 90lb mastiff/boxer mix Indie is very playful, curious and energetic. She needs toys that engage her and keep her busy. This ball does the job! We’ve had it for less than a week. Here’s what I love and what could be better: PROS: • She dog loves it. She whines for it. She gets absurdly excited when I get it out. She’s a bit of an anxious dog, but had zero problems with it inexplicably coming to life. • It lasts a while on a single charge, so it keeps her busy for a good long time. The longest we’ve used it at a stretch is an hour. • It’s pretty durable. She’s a super chewer (destroyed every “non-destructible” toy we’ve purchased for her), but the actual ball is hard plastic. She gnaws on it and it gets scratches, for sure. But she’s not going to chew it to pieces. • On carpet, it’s reasonably quiet. • It comes with a replaceable silicone button. • It’s easy to charge…just pull off the silicone button and the charging port is inside. • The silicone button is flush with the ball’s hard plastic surface, so there’s no way for her to pull the silicone button out and swallow it or get to the charging port. CONS: • Cover is worthless if your dog is a chewer. It goes on like an envelope with a Velcro closure. We took it off immediately. • Without the cover, it’s very noisy on hardwood floors. To us, it’s worth it. (Though, I work from home, so I might feel differently after the holiday vacation.) • She’s an XL dog, so she can fit the whole ball in her mouth easily and accidentally chomp down on the button and turn the ball off. Not a big deal, just something to know if you’ve got a Lab or larger dog. • With extended playtime, the two halves can come unscrewed, especially with a large dog who uses their paws/jaws on it a lot. Thankfully, it makes a loud buzzing noise when this happens, so we know we need to take it from her and screw it back together. Is this a potential danger? With the rechargeable battery inside, I’d say yes. But we also don’t let her play with this toy without supervision. So keep that in mind. Bottom line: It has its drawbacks, but it keeps her entertained and seems like it should last her at least 6 months with supervised play. Which is honestly REALLY good when we’re talking about Indie, Destroyer of Toys. I’d buy it again.

Difficult/impossible to unscrew plastic cups (in order to recharge the vibrating/blinking device)
Color: Orange
Generally, I don't leave feedback on items purchased. However, in this case, I feel compelled to do so in hopes the mechanical engineers (of this product) will take my input to heart and ultimately modify it. First the pros... - I have 2 high-energy dogs (Jack Russell Terriers) who love their toys (e.g., chewing bones, tug-of-war, etc.) but usually get bored with them rather quickly. - This interactive PetDroid ball, however, keeps them busy for a long time. - In fact, my smaller dog (Max) knows its storage location and sits (as early as 6 AM) in front of the cabinet so that I give him "his ball". It keeps him busy for up to 1-2 hours at a time. - Max is literally addicted to the PetDroid ball... his determinant play with it makes me laugh all the time. Now, the cons... - After several days of play, the exterior looks chewed up quite a bit. That's no problem though. - Unfortunately, the interior "threads/grooves" of the two plastic cups (for closing/fasting) are very tiny. - Thus, after an hour-long hard play, it is almost impossible to unscrew the 2 plastic cups in order to recharge the interior device. - It appears the 2 cups somehow come off track and get realigned from the inside. - At that point, I cannot unscrew the PetDroid ball in order to recharge the device.... and without the blinking/vibration, this toy is no longer fun for play. - Ultimately, I had to place the bottom half of the ball into a vise and then use a plumbing wrench to untwist it. Proposed Solution: - Increase the size of the plastic cups' interior threads/grooves so that they won't get realigned/come off track. - This would mitigate the current dilemma of NOT being able to unscrew the ball in order to recharge it. In my view, this should be a relatively simple fix and significantly improve the durability of this product. Thank you for your time.

Good fun and entertaining!
Color: Orange
A really fun interactive toy for your dog! It's pretty erratic and really gets him chasing it. The included soft cover was kinda hard to install and then it's hard to turn it off and on with the cover on, I feel like the cover didn't really improve it at all, sure it's louder without the cover but I feel like dog also likes it that way, he likes loud squeaky toys and this thing making a bunch of noise is appealing to him. We have mostly hardwood floors so it really gets moving, I'm sure on carpet it would be a bit quieter and maybe even a bit slower to move around but on hard smooth surfaces this things can really get zipping around abd get some speed to make him chase it. Overall a fun and entertaining toy.
