Step-by-step guide to installing a sway bar kit on your Tesla Model 3, including tools, tips, and common mistakes to avoid.
Quick answer
Installing a sway bar kit on your Tesla Model 3 reduces body roll and improves handling, and with the right tools and patience, you can do it yourself in a weekend.
Why upgrade to an adjustable sway bar?
The stock front sway bar on a 2017-2021 Tesla Model 3 is 28mm and non-adjustable. An aftermarket kit like the Rekudo 2018-21 TESLA MODEL 3 SWAYBAR KIT uses a 32mm tubular design that is stronger and lighter than solid steel, and includes 3-position adjustability. This lets you fine-tune handling to your driving style, whether you want a flatter cornering feel on the track or a more compliant ride for daily driving.
The trade-off is that installation requires lifting the vehicle, removing underbody panels, and working with suspension components under tension. If you are not comfortable with basic mechanical work, professional installation is recommended.
What you need before starting
Before you begin, gather the following: a jack and jack stands (or a lift), a torque wrench that reads in ft-lbs, a set of metric sockets (10mm, 13mm, 15mm, 18mm, 21mm), a breaker bar, and a pry bar or alignment tool. You will also need the Rekudo sway bar kit, which includes matched front and rear anti-roll bars and all necessary hardware.
A common mistake is not having the correct torque specifications handy. Over-tightening can strip threads, while under-tightening can cause noise or loosening. Refer to your kit's instructions for exact values.
Installation steps
- 1. Prepare the vehicle: Park on a level surface, loosen the lug nuts on all four wheels, then jack up the car and secure it on jack stands. Remove the wheels and set them aside. Use a jack under the control arm to relieve tension if needed. Always use jack stands—never work under a car supported only by a jack.
- 2. Remove the stock sway bars: Start with the front: disconnect the end links from the control arms and sway bar using a 15mm socket. Then unbolt the sway bar brackets from the frame (usually 13mm). Repeat for the rear, noting that the rear bar may be accessed from under the car. Keep all hardware organized. Mark or photograph the orientation of the stock end links before removal—they are handed and must be reinstalled correctly.
- 3. Install the new sway bars: Position the new Rekudo front sway bar and loosely install the brackets. Attach the end links, leaving them hand-tight. Repeat for the rear. Ensure the bars are centered and the adjusters (if applicable) are set to your desired position—start with the middle hole for a balanced feel. Do not fully tighten any bolts until all components are in place and the vehicle is back on the ground under its own weight.
- 4. Torque and final checks: Lower the car to the ground and torque all bolts to the specifications in the kit manual (typically 35-45 ft-lbs for end links and 45-55 ft-lbs for brackets). Reinstall the wheels, torque the lug nuts, and take a test drive on a quiet road to verify no unusual noises or binding. After 50-100 miles, re-check all torque values as the components settle.
