The middle of a GMT400 GMC bench is often the forgotten seat, with a center belt that has been cut, lost or buried in the seat crack for years. Its replacement is a non-reeling hip strap that unlatches at the tip, packed with bolts.
Fit Details
Seatbelt Planet lists it for the front center position of 1988-1998 GMC standard cab pickups with a bench seat.
Color Choices
Fifty-two webbing colors are available, including 13 premium shades. Match the outboard belts for a uniform bench.
Time for New Belts?
A working center belt turns the middle of the bench back into a usable seat for a third rider. Fixed lap belts are simple and have no retractor to jam with dirt.
Caring for Your Belts
Leave both halves of the belt resting on top of the cushion when the middle seat is empty, and clean the strap with mild soap.
About the GMC Sierra Bench Seat, 1988-1998
Standard cab GMC Sierras of this era were offered in short and long bed versions and as two- and four-wheel-drive trucks. Bench seats were common on work-oriented trims and many SLE models.
Pre-Install Checklist
Find the two center anchor points under the bench, clean the threads and check that the floor around them is solid.
Good to Know
Hardware is included.
Adjust the strap length to suit the usual middle rider.
Seatbelt Planet sews the belt in the color chosen at checkout.
A fold-down center armrest may need to be raised to reach the belt.
Fixed lap belts suit the middle position because there is no room for a shoulder strap.
Center belts are often missing on trucks that came from fleets.
This belt pairs with Seatbelt Planet's outboard belts for a complete bench.
Many GMT400 trucks served as fleet or farm vehicles, and the center belt was often the first part removed or lost. Restoring it lets the truck carry a third person legally and comfortably on short trips into town.
Federal standards FMVSS 209 and 302 are met, according to Seatbelt Planet. Because it does not retract, set the length once and it stays where you left it, ready for the next rider.
The end release buckle matches the style GM used across these trucks, so it feels familiar alongside the outboard belts.
Seatbelt Planet sews the strap fresh in whichever of the 52 colors you choose, so it will match outboard belts ordered at the same time.
These OBS-era Sierras are now modern classic trucks with a big following.
