Tesla Model 3 Autocross Package – Adjustable Shocks and Rear Sway Bar Set

A discontinued bundle that combined our Autocross-Spec Adjustable Shocks with the three-way adjustable rear sway bar, sold for Model 3 drivers who needed sharper handling while staying inside autocross class rules that ban aftermarket springs and coilovers. Both pieces bolted to otherwise stock suspension, so the car kept its factory springs and ride height.

No. The product listing is marked discontinued and no longer available, and there is no direct replacement bundle. The rear sway bar half of the package remains available in our 2017-2023 Model 3 adjustable sway bar set, and the damper half’s role is now served by the shocks-only version of our Sport Suspension Kit.

The package bundled the Autocross-Spec shock set with the rear bar, and the shock set itself has been discontinued, which took the bundle off the menu. Details on those shocks, including service options for existing owners, live on the Autocross-Spec shock set page. The handling concept survives: adjustable damping on factory springs plus a stiffer adjustable rear bar, assembled from parts we still sell.

Both halves remain serviceable. The dampers were engineered so an American facility can rebuild and re-valve them, meaning a tired set gets refreshed instead of thrown away. The sway bar has no wearing internals beyond its polyurethane bushings, which are simple replacement items. Contact our team with what you run and we will sort parts and logistics.

Work the dampers and the rear sway bar. Adjustable shocks control body motion on the stock springs, and a stiffer three-position rear bar shifts the balance toward neutral, trimming understeer. That combination transforms cornering while leaving springs, height, and class eligibility untouched. It is the recipe our discontinued Autocross Package followed, and every element can still be bought today.

Rear roll stiffness shifts the handling balance. Stiffen the rear relative to the front and the car rotates more willingly into corners, cutting the understeer that most street cars, the Model 3 included, ship with. On a tight course that rotation is time. An adjustable bar lets you tune how much rotation you want between runs, without touching anything else.

Two orders. Configure the Sport Suspension Kit as shocks only, which keeps your factory springs in place, then add the rear bar from our 2017-2023 adjustable sway bar set in the spec that matches your driving. You end up with adjustable damping and adjustable rear roll stiffness, the same two levers the original package pulled. Verify your class’s current rulebook first, since compliance always sits with the entrant.

Yes. Soft damping settings turn adjustable shocks into a ride quality upgrade over stock, and a rear bar’s softer positions keep the balance civil for commuting. Firm everything for Sunday runs, soften it for the Monday drive. Between events nothing needs to be swapped or removed, only dialed back.

Let your rulebook decide. If you compete in a class that restricts springs and coilovers, damping and bar upgrades on stock springs keep you classed against comparable cars. If no rulebook constrains you, compliance parts are the wrong economy: complete packages like the Stage 3 RS rework dampers, springs, bars, and arms together and are simply faster hardware.

Rules vary by sanctioning body and season, so treat every year’s rulebook as new. The concept this package used, upgraded damping with factory springs and ride height untouched, was written around the rules in force when it was designed, and rulebooks are revised season to season. Read the current rulebook for your class and confirm details with local officials before buying parts around it. Compliance sits with the entrant, not the parts catalog.

Tesla’s warranty covers factory-installed parts, but it does not automatically void your warranty if you install aftermarket components like Unplugged Performance brake kits. Under U.S. law (Magnuson-Moss Warranty Act), Tesla must prove that an aftermarket part caused a failure in order to deny warranty coverage. Our parts are engineered to work harmoniously with Tesla OEM Brake systems and can be professionally installed by Unplugged Performance in Hawthorne, CA or by an authorized installer to minimize risk. That said, any damage directly caused by misuse or improper installation may not be covered. We recommend retaining all factory parts so you can revert to stock if needed. Many Tesla owners enjoy peace of mind by using Unplugged Performance products, which are extensively tested and installed by certified professionals. If warranty concerns are top-of-mind, our team can help clarify compatibility and installation best practices to ensure a worry-free experience.

Unplugged Performance offers a comprehensive warranty on all parts and installations performed by our certified technicians. Warranty coverage applies to defects in materials and workmanship on items including lowering springs, coilovers, big brake kits, brake pads, stainless steel brake lines, shocks, and more. Should any covered part fail under normal use or display premature wear, we will repair or replace it at no additional cost—assuming the component was installed by us or at one of our authorized partners.

This warranty is valid for 2 years or 24,000 miles, whichever comes first, excluding consumable products like brake pads, rotors, and tires, starting from the installation date. Coverage extends to labor for warranty repairs when performed by Unplugged Performance or an authorized installer. It does not cover damage resulting from misuse, accidents, off‑road use, improper installation not done by us, or modifications that aren’t factory-approved.

To file a warranty claim, simply contact our service team. We’ll guide you through inspection, shipping (if needed), and repair or replacement logistics. transparencia and top-tier support are what you can expect from Unplugged.

Installing aftermarket parts does not automatically void your Tesla warranty. Under the Magnusson-Moss Warranty Act (www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts), a manufacturer cannot void your warranty simply because you installed aftermarket parts. Tesla must prove that the aftermarket part caused the specific failure in question to deny a warranty claim. UP recommends retaining all factory parts to allow reverting to stock if needed.
