About the Peterbilt 387
The 387 was Peterbilt's sloped-hood aerodynamic flagship of its era, popular with fleets focused on fuel economy.
Pre-Install Checklist
Check the 387 belt anchor and seat style before ordering.
Good to Know
387 hardware is not stated.
Fleet 387s often pass through several drivers, and the belt is one of the first things to wear.
Order two 387 belts for both seats.
Tug each 387 belt before a run to confirm it locks.
The 387 was popular with large fleets because its aerodynamic hood and sleeper helped fuel economy.
Fleet 387s often pass between drivers, and each new driver adjusts the seat, which tugs the belt.
Air-ride seats in the 387 bounce on rough roads, so the reel must follow smoothly.
A worn 387 belt may be flagged during a roadside inspection.
Black webbing hides grime in a working 387 cab.
Owner-operators who buy retired fleet 387s often replace the belts first.
387 sleepers allow long stretches on the road, so the driver belt may be worn and unworn many times a day at stops.
Retired fleet 387s often show up on the used market with tired belts but solid mechanicals.
A 387 belt that has lost its color from sun through the windshield is likely weaker than new webbing.
Owner-operators sometimes upgrade 387 seats, so check anchor fit before ordering.
Diesel soot in a 387 cab stiffens webbing over time.
A torn 387 belt should be replaced immediately.
The 387's long sleeper and tall roof gave drivers room to stand, and the cab seats were spec'd for long days at the wheel.
A 387 hauling refrigerated loads may run nonstop with team drivers, so both seat belts see double the use.
Peterbilt replaced the 387 with the 587, so belts for the 387 are now an aftermarket item.
A 387 cab with leather or vinyl air-ride seats suits a black or gray strap.
Drivers in a 387 who wear heavy coats in winter need a strap that pays out its full length smoothly.
387 owners preparing for an annual inspection often swap tired belts first, since they are quick to check.
Long-nose fans sometimes prefer the 379, but fleets bought the 387 in large numbers for its slippery shape.
Fleet-spec 387 interiors were usually gray, and a matching gray strap keeps a cab looking factory.
