Chevy & GMC Direct Fit Enclosures
Proline X builds direct-fit enclosures for Chevrolet Silverado and GMC Sierra trucks, cut to the cab they are made for rather than to a generic universal shape. Coverage runs the 2008-2019 1500 and the 2008-2019 HD, in Regular Cab, Double Cab and Crew Cab. Each box is shaped to that cab's own behind-seat cavity, which is what lets it go in as a direct fit with no seat modifications: no relocating the rear bench, no cutting factory trim, no brackets fabricated on the day.
The table below lists every Vehicle Specific enclosure currently live for these trucks, with net volume, mounting depth, external dimensions and driver cutout. Where a fitment is not listed here yet, the Audio Intensity link underneath carries the current Silverado and Sierra lineup.
