Fitment Notes
Listed for 1988-1998 GMC extended cab pickups, driver side only.
Available Colors
Its strap color list totals 52 (13 premium).
Why New Belts Matter
Driver belts take the most use and often fray at the latch plate or edge. Retractors also wear. Fresh webbing and a new reel cure both.
Keeping Them Like New
Keep the webbing inside the cab when the long door closes.
About the 1988-98 GMC Extended Cab
The GMT400 extended cab gave GMC buyers extra space behind the seat, and these trucks were common as work and family vehicles throughout the nineties.
Before You Install
Check the three left-side mounts and clear their threads. The listing does not mention hardware.
Good to Know
It will not fit the passenger side.
Seatbelt Planet makes the belt to order.
Because the listing does not say whether it suits bench or bucket seats, compare it with your truck before ordering.
Driver belts often need replacement first in high-mileage trucks.
End release buckles keep the factory feel.
Test the retractor after installation by tugging sharply.
High-mileage GMT400 trucks often have driver belts that are frayed at the edges or slow to rewind, because the driver belt is used on every trip. Swapping it is a very visible interior upgrade.
Take a picture of the old belt's path first.
Passenger side belts are listed separately because the mounting differs.
.
.
Extended cab GMC trucks were often used as personal trucks and daily drivers, so their driver belts accumulate many years of wear.
Before final torque, sit and buckle up to see that the strap lies flat.
Extended cab trucks have a long door, so make sure the strap clears the latch when the door closes.
Sierra extended cabs with bench seats and with buckets both use a driver belt on the left side, and Seatbelt Planet does not specify which seat style this one suits, so compare its photos with your cab before ordering. Many high-mileage trucks show fraying along the strap edge where it rubs the seat bolster or bench back, and slow rewinding is common as the reel spring tires. A new assembly with fresh webbing and a new reel fixes both problems.
Sierras from this era are becoming modern classic trucks, and interior details matter to buyers.
