PTC Mufflers (Pair)

$93.95

AccuAir PTC mufflers for the VU4 manifold in classic truck air ride builds, a pair that presses into both VU4 exhaust ends to quiet the air dumping out.

  • Quiet drop - the exhaust hiss loses its edge without changing how the system operates.
  • A pair covers the manifold - the VU4 exhausts from both ends and both ends get one.
  • Press in and done - no wiring; no reprogramming; no new plumbing.
  • Reversible - pull them back out if you decide you liked the noise after all.
  • Built for the VU4 - sized to the manifold rather than adapted from a shop-air part.

Install Level: Easy

Sold as a pair.

SKU: AA-3662

In any air suspension system, you will have air springs that take the place of your factory suspension. When deflating your air springs, you will hear an audible release of the air from the springs or bags. While many find this sound very pleasing, others may not. If you are wanting the quietest operation possible from your air springs, you can use the AccuAir PTC mufflers to help keep things quiet. These PTC mufflers simply press into each end of the VU4 to significantly reduce the exhaust noise. This helps to muffle the sound of the air being released and give you an overall quieter operation when airing out or deflating your springs.
