01 Step 1: Lift the Vehicle

1. Carefully lift the vehicle off of the ground using a vehicle hoist. Be sure that the lift points do not interfere with the placement of the UP side skirt installation.

02 Step 2: Remove Bolt Covers

2. Carefully pry off the 4 plastic bolt covers along the lower rocker panel.

03 Step 3: Remove Factory Bolts

3. Using a 10 mm deep socket, remove the 2 factory bolts securing the rocker panel cover to the vehicle body. Note that some vehicles may have varying hardware quantities.

04 Step 4: Test fit side skirt on vehicle

4. Hold the side skirt up to the vehicle. Using masking tape, secure the side skirt to the vehicle. If the bottom side swings away from the vehicle, hand thread a factory 10mm bolt to secure the bottom of the side skirt to the vehicle.

5. Using masking tape, trace the top side of the side skirt directly onto the vehicle paint as shown. This will be used as a reference to apply an adhesive promoter to the bonded area at a later step.

6. Once the scotch tape has been applied, proceed to remove the side skirt from the vehicle.

05 Step 5: Surface Prep

7. With the side skirt removed, using 99%+ isopropyl alcohol, clean the surface below the scotch tape line on the vehicle surface until fully clean. Note that any PPF or ceramic coatings can negatively impact the bond to the vehicle, so removal is highly recommended prior to install.

8. Now, using the provided adhesive promoter, apply adhesive promoter below the tape line in the area where the 3M tape will engage with the vehicle surface.

06 Step 6: Install Side Skirt

9. Before the side skirt is installed, be sure to pull the 3M lead ends for later access. This will allow access to removing the backing tape during installation.

10. Place the side skirt onto the vehicle, and hand thread the factory 10mm bolts to ensure proper placement.

 

11. Once the side skirt is in position, start with one lead end, and pull away from the side skirt while following up with pressure on the exposed tape to bind it to the vehicle surface.

12. Once all of the 3M backing tape has been removed and slight pressure has been applied to the side skirt to ensure thorough contact throughout the adhesive area, proceed to remove all excess masking tape.

13. Using a 10mm socket with factory bolts, torque the factory 10mm bolts to 4ft/lbs. Note if your vehicle has 2 bolts as opposed to 4, you may need to use the provided plastic retainer clips in place of a 10mm bolt for the center 2 mounting points. If your vehicle uses bolts in all 4 mounting points, proceed with reinstalling 4 factory bolts.

Best of the best as always. If you’re contemplating the purchase just buy them and I promise you’ll love the offset/ stance and overall package. You can buy hidden rings or beadlock rings just incase you decide to go to Moab.

Subjectively, these wheels look great. Objectively, it's more efficient than stock, and they feel lighter and smoother. I only have about 7k miles on my Juniper Tesla Model Y, and the second I drove with these newly installed wheels I felt the difference in ride quality. It just feels smoother,...
