Maxton Design Rear Side Splitters V.2 for Alfa Romeo Stelvio Mk1
Give your Stelvio a sharper, factory-style finish at the rear. These rear side splitters extend the lower bumper lines for a clean, sporty look without being over the top.
Designed using 3D scanning, they follow the bumper shape for a precise fit. They are lightweight with a little flex, so they sit neatly once installed.
Fits Alfa Romeo Stelvio Mk1 models from 2016 to 2022. These V.2 rear side splitters are intended to be used with the matching Maxton Design rear components for the Stelvio Mk1. Please use our vehicle lookup or check the Vehicle Fitment tab to confirm compatibility.
Made from durable ABS plastic, widely used in the automotive industry for exterior parts. Finished in gloss black, ready to fit with no painting required.
Supplied as a pair (left and right) with a fitting kit and a step-by-step manual.
For best results, we recommend professional installation unless you are confident using the provided instructions. Test-fit first. The product arrives with a protective film – only remove once you are sure of fitment. Removing the protective film or the holographic verification sticker will void returns. This product is TUV MATERIALGUTACHTEN certified. We cannot be held responsible for incorrect installation or use.
Choosing a Kit
Our vehicle registration lookup system cannot detect factory trim level. It is important for customers to check the specification of their own vehicle against the product description, and if their vehicle has an existing sports trim level, body kit or factory enhancement that may cause it to look different from other similar models.
For example: Volkswagen R-Line, BMW M-Power/M-Pack, Audi S-Line, Ford ST-Line, Merc AMG-Line, Seat FR.
These kits will not fit models that don't meet these specifications.
Returns
Purchased the incorrect kit for your vehicle? Or not sure you like the surface finish when it arrives? No problem!
Maxton Design products are eligible for return if the product has not been fitted, drilled, modified or damaged in any other way and still has the protective factory film intact. Unfortunately, there are no exceptions, this applies to fully removed and partially removed films.
Products with a protective film in place are clearly marked with this sticker, if you believe there to be an issue with the product but you can't tell without removing the film, please contact our support team directly for assistance.

DO NOT REMOVE THE FACTORY FILM UNTIL YOU'VE LINED IT UP, AND YOU'RE READY TO FIT THE PART.
See our Terms & Conditions for more information.
Installation & Fitting
Instructions & Guides
Maxton Design provide either an online reference (below) or printed instructions with their products, we can't stress enough how important it is to follow these guidelines. Not only does this create a safe, aesthetically well fitted product, but it increases the longevity and lifespan of the kit.
Neither Progressive Parts nor Maxton Design will be able to provide and support or warranty for products fitted incorrectly. For example, front splitters require the front bumper to be removed, without doing so the bolts will be incorrectly positioned and may not be able to cope with the down-force exerted on it. Straying from the guidelines in this manner must be done so at the owners risk.
Fibreglass & "Non-Prepped" Products
By adding these products to your basket you are agreeing to the below statement.
All Maxton Design Fibreglass products including certain bumpers, spoilers, spoiler extensions and skirts will require “prep” before installing.
These are not a simple 'ready to fit' modification. In transit, the items may get chipped or marked and as such prior to painting it is important you understand that the parts may require filling, sanding and repairing (defined "prep") prior to paint being applied, which can be undertaken by any reputable body shop at minimal cost.
Return requests based on not anticipating the definition above are not accepted, please be aware you have agreed to this statement and the definition of “prep” work required prior to purchasing.
Product images shown for sale often indicate a finished product, the colour shown on the vehicle is for illustration purposes.
