Under Carpet Lite solves the problem of engine, exhaust and road heat soaking into interiors. Under Carpet Lite is a superior sound decoupling material for those hard to cover areas like door liners, rear decks, headliners and more. Under Carpet Lite (UC Lite) is a 1/2 in. thick multi-layer, high tech composite material designed to be extremely flexible and easy to install. UC Lite offers maximum thermal insulation in a lightweight padding (approx. 0.23lbs per square foot) that provides less heat transfer in the summer while protecting against the transfer of cold air in the winter. UC Lite is also equally effective as a sound deadener that prevents the transfer of noise, including rattles and squeaks to ensure a like new driving experience and add longstanding value to your investment. The multi-layer polyester/fiberglass composite material offers unmatched thermal and acoustic protection in an extremely flexible light weight package UC Lite is recommended for use either alone, or as an added sound decoupler with Boom Mat vibration dampening material. Under Carpet Lite can be installed under carpet, behind door panels, under headliners on fire walls, or any interior location. To install, simply fasten mechanically to the area, or tack in place with Boom Mats Improved Formula Hi-Temp Spray Adhesive (10492). Hi-Temp Spray Adhesive works well on both vertical and overhead surfaces. What's in it for you. Comfortable interior at any temperature Quick and easy installation Enhances stereo performance and sound Economical insulating solution Lightweight for high performance applications Where to use: Floor pans Fire walls Transmission tunnels Behind back seats Inner fender wells Trunk floors Rear quarter panels Under headliners Kick panels

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
