GENERAL INFORMATION
PRODUCT DESCRIPTION

The concept of Ascension to us means bringing the underlying Tesla vehicle to a higher level. With the Model Y Ascension Rear Diffuser, we have kept the Y’s original soul in a more aggressive and premium package.  In this, case the original Tesla Model Y has a unique rear diffuser line that dips down in the center to encapsulate the tow hitch cover and we wanted to carry that design DNA into a more aggressive and track-focused rear diffuser by maintaining the original design but moving it upward to give the diffuser the visual weight of being much lower than the original diffuser.  We have also created a side profile that also provides a lower visual weighting for the Y to bring the bottom of the rear fascia inline with the side skirts and let the disrupted air from the rear wheel well and tire flow back cleanly around the rear of the vehicle.

When paired with the Unplugged Performance Tesla Model Y front fascia (bumper) and the Unplugged Performance Tesla Model Y High Efficiency Trunk Spoiler it creates a unique aerodynamics package for the “world’s fastest SUV.”

Diffuser package includes:

  • Rear Diffuser (aka Rear Fascia Lower) in Pre-Preg Carbon Fiber
  • Rear Tow Hook Cover in Pre-Preg Carbon Fiber
  • Rear Hitch Cover in Pre-Preg Carbon Fiber

This product replaces the following Tesla original parts:

  • REAR FASCIA, LOWER 1494006-00-B
  • COVER TOW HITCH 1494009-00-A
  • TOW HITCH COVER 1494009-00-B

NOTES:

  • This product requires the original Tesla rear reflectors but does NOT include them as we anticipate you will reuse your existing reflectors.  If you need to purchase the reflectors due to damage incurred to your vehicle please purchase them (LAMP ASY, REAR REFLEX, LEFT HAND 1495817-00 and/or LAMP ASY, REAR REFLEX, LEFT HAND 1495817-00) as needed before installing.
  • Customers worried about potential rock chips in the gloss clear coat are recommended to install paint protection film before installation.  There is no warranty on visual damage from rocks or other road debris and the rear fascia is located in an area where they will sustain regular impacts.  The original parts are made of plastic in this area to reduce road debris damage.  Carbon fiber is much more susceptible to this sort of surface damage.  The effectiveness of the diffuser will not be degraded by visual blemishes.
  • Due to the height of the Model Y, the effectiveness of any ground effects is largely negated by the ride height. Customers looking to improve the aerodynamic efficiency of the vehicle through this modification may not see significant gains at reasonable ride heights.
  • Professional installation is highly recommended.

What our customers say
You can see my photos on the site under Steve Guevara to see the detailed work that went into the front fascia unit. I said before that my skeptical wife told me to pick out the car that I wanted, so I liked the TM3 the best as my kids are away at college and now it is my turn to be spoiled. I also...
I was not going to get these, as I do not track my car. I love the any chance to control as much about my car as possible. Just one more way to stand out from the crowd. And, I can get my tires to last a reasonable amount of miles.
Psychologists say that the more you pay for something, the more you like it. Maybe that’s what’s happening here, but the front fenders are now my most cherished upgrade. I love that I can unlock up to a 315mm square setup with a track camber and 305-295mm with a daily camber. I’ll never be...
UP Pikes Peak Race Team Soft Shell Jacket by North Face You can see my photos under Steve Guevara. The UP Jacket I first noticed on the Pikes Peak video on the set in the shop and I asked KIRK, “Do you have some of those”? He pulled two Medium beauties from the vault and added a couple of...
Love these 6-points Harness in our S Plaid drag race car. Looks so amazing in the car with the UP carbon fiber seats..👌🏾
We got these (BBK) installed on our S Plaid was the best think we could have upgraded first. They feel so great when stopping on the big end on the tracks, So much light weight as well from the factory stock brakes. Thanks
Product is top notch when I installed them it was like switching from a 1 piston sliding caliper to a bbk. Also cold performance and noise are really good

You can see my photos under Steve Guevara. WHEELS, what to say about this indescribable addition. There are so many incredible things added to my SMG3, but this wheel set altered the car drastically. The RIDE is much improved with the grip around tight corners like Topanga Canyon with the other four...
Unplugged Performance UP Emblem You can see my photos under Steve Guevara. The UP Emblem, just another seemingly innocuous item that KIRK added to make the car pop when driving behind it. The sun shines on the titanium and it screams at you and then goes back into its subtle way. To say that I love...
After using the fascia for over two years, this feels like a must-have Tesla upgrade. The stock Model 3 just doesn’t look the same anymore. I would recommend epoxy over double-sided tape to secure the ultrasonic sensors for a longer-lasting, flush fitment.
You can see my photos under Steve Guevara. Wow, what to say about this spoiler. There are so many incredible things added to my SMG3 that since I have brought it home less than a week ago, I have had more that fifty conversations from strangers that absolutely have to have this spoiler. It...
The ascension front fascia makes my model 3 look so much sportier and aggressive. I’ve had it on my car for over a year now and I love it. The car looks way better than stock. This is how the car should look coming out of the factory.
I’ve worked on cars and pushed them close to their mechanical limits all my life. This Model S Plaid definitely needs a brake upgrade if you tend to push your car harder than the average driver lol. The BBK install was pretty straight forward. You can use the instructions provided or with no...
Exactly what I wanted. Much better appearance. Beautiful stance. Both stiffer in the corners and smoother on the regular road imperfections. Feels more tuned and prepared. Will recommend to all my Tesla owning friends.
After using the fascia for over two years, this feels like a must-have Tesla upgrade. The stock Model 3 just doesn’t look the same anymore. I rate 4/5 stars since epoxy would be better than double-sided tape to secure the ultrasonic sensors.
Same as the fascia, this feels like a must-have Tesla upgrade. The stock Model 3 just doesn’t look the same anymore. I love the dry carbon material and would highly recommend. I wish the diffuser fins came standard, even with a higher cost. With some DIY, you can make the air ducts in the bumper...
An absolute MUST when thinking about your first upgrade. The Model Y, even in it's Performance Model, has more body roll than you'd like. It was one of my biggest complaints when driving the first few months. After installation, body roll was greatly reduced. Cornering on-ramps and turns with a...
These Rear brakes was a big help with our S Plaid drag racing car.Feels great and paired with the Front (BBK) & Upgraded to Racing brake fluid with the stainless steel lines. Thanks
For my 2018 Model 3P I got the mild springs. Amazing! The ride feel is even better than I was hoping for. The car is my daily driver and the harshness of the stock springs with the 20" rims made me consider switching to 19". Instead I figured I try UP's dual rate springs first since it seemed to...
These carbon fiber seats are amazing in our plaid drag car. Looks like it came from Tesla just like that. 🔥🔥🔥 Thanks
