Product Description
1989-1991 GMC Pickup Truck, Crew Cab, Rear Bench Seat Belt Kit
- Rear driver, passenger and center positions
- Three-point retractable lap and shoulder belts
- End release buckles
Back-seat riders in a 1989-1991 GMC crew cab get three new restraints from this Seatbelt Planet kit, each closing in an end release latch rather than the all-metal style used on the Chevy version.
Fitment
All three positions on the rear bench of 1989-1991 GMC four-door pickups.
Webbing Colors
Fifty-two webbing shades are offered, and all three GMC straps come in the color you choose.
Why Replace?
GMC crew cabs from these final square-body seasons were popular with horse owners and RV towers, and the rear bench belts often carried kids and dogs for hundreds of thousands of miles.
Belt Care
Rinse GMC rear webbing gently with mild soap and allow it to air dry pulled out of each reel.
About the GMC Crew Cab Pickup
While GMC moved its light-duty Sierra to the GMT400 platform for 1988, the four-door GMC crew cab stayed on the older square-body design until the 1991 model year ended.
Before You Install
Pull the GMC rear seat bottom forward to inspect the floor anchors for rust before you order.
Good to Know
Seatbelt Planet's listing does not state whether hardware ships with this GMC set.
Sierra Classic and High Sierra trucks were the dressier GMC trims, often with cloth rear benches in blue, tan or burgundy.
Buying the three-belt set keeps the GMC back seat uniform instead of mixing new and old webbing.
Most four-door GMC trucks of this period were 2500 or 3500 models, many with dual rear wheels for heavy towing.
Owners restoring a late square-body GMC often handle the rear belts along with new carpet and seat covers.
Check the length of the original GMC middle buckle before ordering so the new latch sits where passengers expect it.
Late GMC crew cab owners sometimes restore their trucks to factory spec, and end release latches match the look many of these trucks had when new.
Dually GMC 3500 four-door trucks from 1989-1991 are favorites with fifth-wheel camper owners, and rear seat belts often carry family members on long trips.
Owners who rebuilt their GMC rear seat with new foam often find the old belts no longer fit neatly through the cushion gaps.
When the GMC rear seat is folded forward or removed, the retractors keep each strap wound neatly near its anchor.
Seatbelt Planet also lists individual rear outer GMC belts if you need just one side.
Sierra Grande, High Sierra and Sierra Classic badges appeared on these GMC trucks over the years, and rear seat upholstery varied by trim.
