Bench-equipped GMC extended cabs have a middle front seat, and this listing gives it a fixed strap with an end-latch buckle.
Vehicle Fit
Listed for 1988-1998 GMC extended cab pickups, center position. Its title calls it simply an extended cab seat belt, and the description identifies it as the center belt.
Choosing a Color
Shades: 52, including 13 premium. Match the outboard belts for a uniform bench.
Why Upgrade?
Center belts often end up lost in the seat crease or damaged by the seat track. Replacing it brings the middle seat back.

Rest both ends on the GMC bench when unused.
About the GMC Extended Cab Pickup
GMT400 extended cabs with a bench and column shifter were popular work trucks, carrying three across the front.
Pre-Install Checklist
Locate the center anchors under the bench, clean the threads and check the floor. Hardware is not mentioned.
Good to Know
One belt for the center position.
Fixed lap belts have no reel to collect dust.
Seatbelt Planet makes the belt to order.
Raise any center armrest to reach the belt.
Set the strap length for the usual rider.
A working center belt adds practicality to any bench seat truck.
Bench seat GMT400 extended cabs were common on work trucks and base models, and many carried three people across the front. A working center belt brings that seating back, especially useful for families or crews.
Allow a little slack for easy buckling.
Order outboard belts in the same color for a uniform bench.
The listing's title does not specify the position, but the description identifies it as the center belt.
Bench seat extended cabs are often used for hauling a helper to the job site, so a working center belt is useful every day.
GMT400 extended cabs with bench seats are common on the used market, and many are missing their center belts. A replacement makes the truck ready for three riders up front.
Seatbelt Planet makes the center belt in your selected webbing color, and matching the outboard belts keeps the bench uniform.
Fixed lap belts are simple and durable.
Because the strap is fixed, there is no reel to jam with sawdust or grit, which suits a truck that hauls tools and building materials. Choose the shade used on the extended cab's outer belts, and the whole bench will look coordinated.
Bench seat GMT400 extended cabs are now collected as nineties classic trucks.
Seatbelt Planet sews each strap to order, so the color you select is made fresh for your GMC.
