Boom Mat Undercarpet(TM) (TM) is a second layer sound deadening and insulation mat that will help you maintain a quality ride experience by preventing unwanted noise from being transferred into the vehicle interior. In addition to its sound deadening properties this two layer acoustic material provides superior insulation keeping vehicles cool in the heat of summer, and warmer in cold temperature climates. UC is made up of a top layer of flexible one pound per square foot mass loaded barrier material, and a bottom layer of high quality industrial acoustical marine grade foam. These combined materials offer the most ideal way to maintain a new car driving experience by eliminating squeaks rattles vibration and unwanted engine noise and heat. UC can be added under carpet on fire walls or anywhere in the interior of a vehicle where additional sound deadening or insulation is needed. For the ultimate experience in a quiet ride and interior comfort Boom Mat recommends using UC over Boom Mat Vibration Dampening Material. UC can be mechanically fastened or tacked in place with Boom Mat Hi-Temp Spray Adhesive ( 010490) including vertical and overhead surfaces.

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.
