This Seat Lift Modification Kit fits 2008-2018 GMC Sierra Crew Cab and Chevy Silverado Crew Cab.
Our customers generally buy this to achieve a 2” Lift in order to fit our Ported Subwoofer Box that fits 2-10” Subwoofers (Pictured in Photos) that we sell separate for additional $275.
Attention:
Hardware kit consists of 10-nuts and 10-bolts.
Pictures of 2-10” box are just to show example of how box looks under the seat after the Seat Lift Modification Kit.
