Sound Control Kit by Design Engineering - Polaris Xpedition 4-Door

Quiet the Ride with the Design Engineering Sound Control Kit

The Ultimate Noise & Vibration Solution for Your Polaris Xpedition 4-Door

The Polaris Xpedition is built to conquer the toughest terrain, but all that power comes with plenty of cab noise, vibration, and heat. The Sound Control Kit by Design Engineering (DEI) is the ultimate solution, engineered to transform your machine's interior into a quieter, more comfortable cabin. This comprehensive, premium kit significantly reduces engine noise & vibration while acting as an effective thermal barrier, allowing you to actually have a conversation with your passengers or enjoy your music without screaming over the engine roar. Proudly made in the USA, the entire kit is built from durable, high-quality materials and provides a clean, factory-finished look.

Targeted, Multi-Zone Protection

DEI didn't take a one-size-fits-all approach. This kit features specialized, precision-cut materials designed to tackle noise and temperature transfer at every major source:

• Cabin Roof (D-Mat Insulation): The roof section features D-Mat insulation that is precision CNC-cut to fit seamlessly inside both the front and rear headliners. This high-performance material delivers highly effective sound deadening and thermal insulation across the entire roof area, keeping your cab cooler in the summer and warmer in the winter.
• Tail Gate, Cargo Sidewalls, and Seat Base (Boom Mat Felt-Finish): High-noise areas are treated with CNC-cut Boom Mat Acoustic Material. Constructed from 2mm thick butyl rubber with an attractive, wear-resistant felt-finished surface, it absorbs and deadens airborne noise while blending perfectly into your cab. Plus, the convenient self-adhesive backing makes installation quick and painless.
• Cargo Floor and Rear Firewall (Boom Mat Aluminum-Finish): To block massive engine and exhaust heat from entering through the rear, this section utilizes Boom Mat installed beneath the factory cargo liner for complete, wall-to-wall coverage. This 2mm thick butyl rubber features a rugged finished aluminum facing and a self-adhesive backing. The material is trim-to-fit and installs quickly, offering superior sound-deadening and heat-blocking performance.

Simple Installation, Professional Results

You don't need a professional shop to get professional results. With an estimated install time of approximately 4 hours, this kit is designed for a straightforward DIY garage project. The combination of precision CNC-cut pieces and peel-and-stick adhesive backings ensures a frustration-free install that looks like it came straight from the Polaris factory.

Enjoy the rugged capability of your side-by-side without the punishing cab noise. Upgrade your machine with the DEI Sound Control Kit and ride in comfort!
