The ST X Coilover suspension was developed for the everyday driver who needs to hug the curves yet retain road comfort. Simple, uncomplicated road performance for those who just want to get in and drive. Add in our wide range of height adjustability; the ST X Coilover will look as perfect as it feels. ST XCoilover kits deliver precise adjustment to your ride height and look of your car. We manufacture an adjustable spring perch made of durable and friction-optimized polyamide composite material with a stainless steel insert. Thanks to the composite material corrosion is prevented between the strut and perch ensuring long lasting height adjustability. Galvanized zinc coated steel struts optimize corrosion protection for long lasting use. We add a dust protection system to prevent unwanted dirt and particulate from coming in contact with the hardened chrome piston rod or getting into the valve packs. We reinforce the system with a multi-layered pressure resistant sealing package, mono block guide system and a low friction piston band which works inside the pressure resistant internal damper housing. At ST suspensions we do not accept compromises. As a matter of principle we rely on world class engineering delivered from KW for all our dampers. Why? To simply improve your driving experience! All ST X Coilover kits are application specific for your car and perfectly adapted for everyday life.

  • Elastomer Bump stop with integrated dust protection system prevents water and dirt particles reaching the piston rod and seals. The highly resilient bump stops act as dynamic load limiters while maintaining ride quality and durability.
  • Composite spring perch made from wear-resistant, friction-optimized polyamide composite with an embedded stainless-steel insert. The polyamide composite prevents oxidation while the stainless-steel insert maximizes strength.
  • ST X coilovers are the ideal mix of sporty yet simple. The dampers and spring rate come tuned by our vehicle dynamics engineering in Germany to perfectly match each vehicle specific application.
  • ST coilovers are built by hand by the experts at KW in Fichtenberg, Germany. Each damper is tested on a shock dyno to verify it's making the proper forces before being put into the ST box.
  • Seamless Ride Height Adjustment - ST's composite spring perch and unique trapezoidal thread pitch make ride height adjustability a breeze so you can dial in your preferred look.
  • Galvanized steel housing for improved resistance to corrosion.
  • 5 Year Limited Warranty - Unlimited Mileage
  • Made in Germany

Don’t buy
Size: Eufy E25 Omni / E28 Omni E28
Black roller brush doesn’t fit. Quality is not the same as eufy. The filter doesn’t have as many pleats ergo doesn’t filter as well.

Perfect Fit for Eufy E25 - Great Way to Refresh Your Vacuum
Size: Eufy E25 Omni / E28 Omni E28
This replacement kit worked perfectly with my Eufy E25 robot vacuum/mop. All of the parts fit as expected, and it was nice to be able to swap everything out at once rather than replacing pieces individually. After installing the new brush, mop, filters, and other components, my machine is running noticeably better. Super easy to do. The set includes a good assortment of replacement parts, making it a convenient way to refresh your vacuum and keep it working efficiently. A great value and an easy way to extend the life and performance of your robot vacuum.

Complete Replacement Set
Size: Eufy E25 Omni / E28 Omni E28
This replacement parts kit is a convenient way to keep a compatible robot vacuum running efficiently without having to source each component separately. The included rolling brush and side brushes help maintain strong cleaning performance by picking up debris effectively, while the filters support proper airflow and dust capture. The dust bags are a useful addition for keeping the self emptying system working smoothly over time. The roller mop also fits well and helps maintain the mopping function without needing frequent replacements. Having a full set like this makes routine maintenance much easier and helps extend the overall lifespan of the vacuum.

Mop won’t lock and black roller won’t fit
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
We’ve had our E28 for about a year now, so it was time to change out some of the more worn parts. This kit looked to have everything I wanted to swap out. It came with two sets of sweeper brushes, two center brushes, the roller mop brush, two dust bin filters and several disposable dust bags. I was able to get all of the parts to fit on our E28 except the black side main brush. It looks like the diameter of the hole isn’t correct for the model, but the grey side was (see photos and video comparing this set to factory set). The roller mop looked very similar except it had a slightly less high pile. The pieces all seemed good quality over all. Putting the new parts on was easy otherwise and they fit well. I sent out our E28 for a whole house cleaning and it did well both vacuuming and mopping, or at least on-par with the factory parts with the same noise level. The aim issue was that the roller mop wasn’t locking in place, and when it went to try to wash the mop and popped the whole vacuum out of its base cradle and threw an error a couple times throughout the cleaning. I just had to manually push the roller mop back in and it worked fine until the last wash and then I couldn’t get it to stop throwing the error. So, 2/5 stars for the one piece not fitting and the roller mop having issues during the mop washing process. Guess I’ll have to order from Eufy directly.

Direct replacment for omni E28!
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
This kit is an excellent value and contains direct replacement parts for the Eufy E28 Omni. Everything in the box from the rolling brush and the roller mop to the filters and dust bags matches the original components perfectly in size and fit. ​I found that the side brushes and the main roller installed easily without any forcing, and the vacuum performance remained consistent with no loss of suction or strange noises. The HEPA filters fit snugly in the housing, and the dust bags slide right into the docking station just like the brand-name ones. It is much more cost-effective to get this entire bundle than to buy these items individually. If you need to refresh your E28 Omni, this set is a reliable way to get it back to peak performance.
