Tesla Model 3 and Tesla Model Y Billet Height-Adjustable Rear Spring Arms – Ultimate Edition

Yes. The same system raises the rear above factory height, which owners use for winter driving or rougher roads. UP notes their coilovers also have adjustable-length shock bodies that can exceed stock height, so the front can follow. Because adjustment is just turning the 32mm socket, going up for the season and back down later is quick.

It is a perch-less rear spring UP developed with Hyperco so you get fully adjustable rear height with no travel-robbing perches or adapters. The bottom is 65mm and the top is shaped specifically for the Model 3 and Model Y, which allows unrestricted spring travel and lets the car sit lower than the factory arm without switching to a shorter spring. It runs $175 as an add-on and suits a sporty yet everyday rate.

They are machined from 6061-T6 billet aluminum and finished in Cerakote to preserve the bare machined look. Assembled weight is 7.8 lbs per side, and pairing them with coilover rear springs actually removes weight by deleting the separate rear spring perch. Design used 3D scanning and FEA strength analysis, with set screws front and rear to lock the seat in place.

They solve a different problem. A coilover kit sets damping and overall ride character; these arms make rear ride-height changes fast and let the Model Y sit lower without sacrificing travel. They are made to work with UP coilovers, not replace them. If you want four-way adjustable damping on top, the UP x Ohlins Nur SPL TTX coilover set is the high-end pairing, and these spring arms complement it.

That is up to how you use the car. Corner-balancing at the shop, dropping it for a track weekend, or raising it for winter are the common reasons, and each takes minutes here. Some owners set a height once and leave it. The point is that changing it later never means pulling springs again.

UP warranties these for 200,000 miles and includes off-road and racing use, which is unusual, plus a 30-day money-back guarantee. The warranty is non-transferable. These are priced at $1,395 as the no-compromise rear spring arm, so the coverage matches the intent of a part meant to outlast the car it is bolted to.

The spring seat is built into the arm and moves up or down when you turn a standard 32mm socket, so you raise or lower the rear without swapping springs. Machined up and down indicators show where you are. It means a rear ride-height change at the track or the alignment shop takes minutes with a jack and a wrench, not an afternoon of parts.

Yes, but you need the right rear spring. These arms are compatible with all current-generation Unplugged Performance coilovers with nothing further to buy. Without coilovers you will need an appropriate rear spring set, and UP offers a purpose-built 65mm-bottom set as a plug-and-play add-on. The arms accept 65mm or 2.5-inch ID springs, with a common length around seven inches.

They install rapidly on any Model 3 or Model Y, and at checkout you pick Model 3 2017-2023 pre-refresh, Model 3 late-2023 refresh, or Model Y. UP developed and validated the design on both the 3 and the Y across street and track driving. They install with factory hardware, so the swap uses the car’s existing mounting points.

On the Model Y these let the rear go lower than the factory spring arm allows without forcing you onto an extremely short spring with harsh rates and little travel. That was a specific design goal: more drop while keeping usable spring travel and ride quality. UP set racing lap records with both the Model Y and Model 3 running these arms, the kind of setup you can bring to a TeslaCorsa track day, then kept daily driving on them.

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.
