Tesla Model Y Ascension Rear Carbon Fiber Diffuser With Hitch Cover & Tow Hook Cover

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

UP Carbon parts are engineered using advanced prepreg-autoclave technology with our proprietary dry-carbon-kevlar backing layer. This superior method, with resin integrated during production, delivers exceptional strength-to-weight performance compared to traditional wet-layup or vacuum infusion methods.
Finish Options

  • Gloss Base Coat: Showcases the carbon weave pattern with a glossy finish
  • Satin Base Coat: Offers a refined, contemporary aesthetic

Base Coat Information
Our parts feature a base coat finish that displays the carbon fiber weave. These finishes serve as a foundation and can be enhanced through professional clear coating or protection film services at your local automotive facility. As these are base coat finishes, warranty coverage excludes all cosmetic outcomes including UV-related fading, discoloration, scratches, rock chips, and finish degradation.

Warranty Coverage

  • 5 year structural warranty on fitment and functionality for the original owner.
  • Base coat finishes are provided as-is as a no-cost time-saver to prepare the parts for recommended clearcoat or paint protection.
  • Compatible with recommended professional clear coating and paint protection services.
  • Warranty does not cover visual degradation or discoloration from UV or other damage for unprotected parts.

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.

      I love the front ascension fascia! Really changes the whole look of the Model 3. My least favorite part of the car was the front bumper and this changed it all for me. Noticeable improvement in downforce as well which is a nice touch. Totally transformed the car and I couldn’t be happier. Also...

      Got the Street/Track version for my 2022 Performance 3 and couldn't be happier with them. I combined them with the Moderate Lowering Springs and this combo is perfect. The turn in is quicker and with the reduced body roll it makes the handling now better match the acceleration abilities of the 3. ...

      These brakes perform great and I should have upgraded to these a long time ago. Pedal travel with with the included brake lines are much improved as well.

      I had my Coilovers installed by NV Auto in Hamilton Canada. They did a good job and I now have a great ride. After about a month of driving I went one step further and put new 18” rims and tires on. This really improved the ride and is is a joy to drive my Tesla again. Thanks unplugged...

      Installed this on my CyberBeast in my own garage. The instructions provided were top notch with outstanding attention to detail. I installed the bar in the middle position. On the first turn I noticed the decrease in body roll. The turn in and mid turn stability is much improved. I am very...
