INSTALLATION INSTRUCTIONS: SX-2

Estimated Labor: 1-2 hours

Parts and Tools Necessary

• 15mm, 18mm, 21mm wrenches and sockets
• T30 Torx bit
• 8mm Allen key
• Screwdriver or other small prying device
• Torque Wrench
• Nylon lock nut (Part #2007076, Tesla recommendation)

Before Install

• If the vehicle is equipped with air suspension, activate Jack Mode through the touchscreen before lifting the vehicle. The air suspension will attempt to self-level otherwise, which may cause serious damage, bodily injury, or death.
• Make yourself familiar with the proper way to jack and lift your Tesla before attempting installation.

Removal

1. Jack the vehicle up from the appropriate lift areas, as shown below. Using lift pads between the jack and the vehicle’s frame is highly recommended in order to avoid damaging the vehicle.
2. Loosen the lug nuts (21mm) and remove the wheel.
* Take note of the position that the sensor link sits at. The link must be re-installed in the same position, as the vehicle may not read the ride height correctly otherwise.
3. Pry off the short sensor link from the ball attached to the original camber arm. This can be done with a large flat head screwdriver or small pry bar, gently using the original camber arm as a fulcrum point. Always exercise caution when dealing with the links, as they have many points of failure.
4. Remove the bolt that connects the camber arm to the knuckle (15mm).
5. Remove the nut and bolt that connect the camber arm to the subframe (18mm).
6. Remove the camber arm from the vehicle. If you are having trouble removing the camber arms, rocking the knuckle/hub may aid in loosening and removing the arm.

Installation

1. Verify that the arm being installed is correct, as the SX-2 is mirrored for the driver and passenger sides. The SX-2 should be around the same length of your stock arm, which can be verified by passing a bolt through both bushings. The rod-end bushing is to be installed on the subframe side, and the ball stud for the sensor link should be facing forward.
   2. Realign and hand-tighten the nuts and bolts in their original positions. DO NOT torque the nuts or bolts at this stage. Note that aligning the hub side first will result in an easier install.
   3. Preload the suspension before torquing down the bolts. This can be done by jacking the knuckle up until the suspension is fully loaded. The car itself should feel like it is about to lift and the hub should be positioned as if the car was sitting on the floor. This step is critical in ensuring the bushings are correctly positioned when you drive the car.
   4. Once preloaded, torque the bolts down to their appropriate settings. The bolt towards the subframe should be torqued to 96 ft/lbs (130Nm), and the knuckle side to 103 ft/lbs (140Nm).
   5. If installing back original links, apply a small amount of white lithium or other appropriate automotive grease in the socket. Carefully press the link back onto the camber arm. 
   6. Remount the wheels back on the vehicle and torque down the lug nuts to 129 ft/lbs (175 Nm). Make sure to remove all jack stands and tools from under the vehicle before you let it down.

Adustment

-Adjustment of the SX-2 is to be made using the 30mm wrench provided along with the arms. Other wrenches will likely be too large and damage the bracket, which may result in an inaccurate reading on the engraved scale.
-Loosen the T30 Torx bolt on the black collar as well as the 8mm allen bolt on the body of the arm. Both of these bolts must be loose for adjustment to be made.
-Tighten or rotate the adjuster clockwise in order to increase negative camber. Loosening or rotating the adjuster counter-clockwise will reduce negative camber.
-Once you are done adjusting, torque the 8mm and T30 bolts to spec. The 8mm allen should be tightened to 24 ft/lbs or 32.5 Nm, and the T30 Torx to 8 ft/lbs or 11 Nm. Make sure the collar with the T30 is aligned with the rod end to avoid damage while driving.
