Product overview

The Mega Pak is the largest single-purchase option in the Dynamat Xtreme range. Nine sheets at 609mm x 1219mm provide enough material to cover doors, floors, roof, rear deck, trunk, and quarter panels across most standard vehicles. Dynamat Xtreme uses a butyl rubber compound bonded to an aluminium alloy skin and formulated with Vector Chemistry, giving it strong damping performance and the flexibility to stretch and conform around curved and ribbed panel surfaces without tearing. At 2.16mm, the Mega Pak sheets are the thickest in the Dynamat Xtreme range, delivering maximum damping efficiency for high-noise environments. The aluminium skin handles high-temperature areas including firewalls and under-hood surfaces. Self-adhesive butyl rubber backing bonds to bare metal without surface preparation or a heat gun.
