Automotive Custom Lighting Aftershock / Howler Bracket - Silverado

Put low-frequency punch under a 2023-2026 Chevrolet Silverado or GMC Sierra 1500/2500HD. This bracket hangs a SoundOff Aftershock or Whelen Howler subwoofer beneath the cab using the factory side step mounting holes — driver side, passenger side, or both — so intersection-clearing bass goes exactly where you want it.

Key Features & Upfitter Specs

  • Function: Purpose-built under-cab mount for SoundOff Aftershock and Whelen Howler low-frequency speakers.
  • Factory Holes: Bolts to the OEM side step mounting points — no drilling into the frame.
  • Configurations: Driver side, passenger side, or a pair for both sides.
  • Hardware Note: Requires 8x M8x1.25 bolts and 4 trim screws (hardware not included).
