No Expense Spared Engineering. Creating and Solving The Ultimate Wish List.
When developing these rear spring arms we created a wish-list born out of our racing experience setting lap records at the track as well our experience working on 1000s of customer cars.
Our wish list looked something like this:
– At the race track, rapid ability to increase/decrease ride height with just a jack and a socket wrench
– During corner balancing enabling the ability to perform rapid height adjustments on the spot
– Specific for the Tesla Model Y: Enabling the rear suspension heights to go lower without requiring an immensely short spring with extreme spring rates and reduced spring travel
– Ability to exceed lowest height spring orientation on Model 3 and Model Y allowed with factory spring arms
– Enable rapid raising of the car for winter use or offroading (all Unplugged Performance coilovers have adjustable length shock bodies and have the capability to go higher than factory ride height)
– Reduction of additional parts and weight by eliminating rear spring perch
* Optional rear spring set: Develop a rear spring that is height adjustable without any additional hardware (no bottom perch and no spring top adaptor either)
Results
The above wish list items were all solved over multiple design iterations and testing lasting nearly a full year. In the process, we’ve managed to retain ride quality while going lower than ever possible without compromise on the Model Y rear suspension. We’ve also managed to lift another Model Y to new heights with this same system. We’ve set racing lap records with the Model Y and Model 3 both using these parts and continue to daily drive on them. Throughout all of the testing, we’ve enjoyed newfound ease in setting rear ride height by simply turning the 32mm socket.
Selecting The Right Plan For Your Car
These will rapidly install on any Model 3 or Model Y. If you already have coilovers please verify rear spring ID size with the manufacturer if they are not made by Unplugged. These arms accept 65mm or 2.5” ID which are common spring sizes. Adaptors from 65mm to other larger sizes may be possible by 3rd party as well. A common rear spring length is frequently 7”. These spring arms are compatible with all current-generation Unplugged Performance coilovers and nothing further needs to be purchased to fit. If you do not have coilovers, you will still be able to use these however you’ll need to purchase an appropriate sized rear spring set. We’ve made a special rear spring set for this purpose and we offer it as a plug and play package.
Optional Perch-less Unplugged Performance x Hyperco Rear Coilover Spring Set
One of our wish list items was to have a fully and rapidly adjustable rear ride height without the use of any spring travel inhibiting perches or adaptors. Typically a height-adjustable purchase is required on one end of a spring meanwhile an adaptor is required on the other end of the spring to securely fit coilover springs. We’ve developed a purpose-built rear spring set in a sporty yet every day suited spring rate that requires no adaptors or additional hardware. The bottom of the spring is 65mm and the top of the spring is Tesla Model 3/Y specific shape. This allows unrestricted spring travel, unprecedented fast height adjustment, and the ability to go lower than the factory spring arm allows without the need to go with a shorter spring and less spring travel.

Will upgrading my brakes void the Tesla warranty?
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.
What does the Unplugged Performance product warranty cover?
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.
Will Tesla void my warranty if I install aftermarket parts?
A vehicle’s comprehensive warranty as a whole may not be voided due to use of aftermarket parts per the Magnusson-Moss Warranty Act (www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts). However, a manufacturer may require a customer to pay for parts and labor for a repair if there is direct causation between a customer’s alteration and the product or service repair being requested. It is in both manufacturer and customer’s interest to follow logic and reason so that the system of good faith is not abused. If this topic interests you please read the law as well as your warranty documentation. Ultimately we are Tesla owners and enthusiasts, we are not lawyers and cannot provide legal advice.
