Fit Details
Listed for the driver and passenger seats of 1980-1986 Mercedes-Benz 380 SL models.
Color Choices
There are 52 webbing colors to choose from, 13 of them premium.
Time for New Belts?
Sun exposure in an open car fades and weakens webbing, and the reels in older cars can become slow. A new pair restores both function and looks.
Caring for Your Belts
Choose a shade that resists fading if the top is often down, and clean the belts with mild soap.
About the Mercedes-Benz 380 SL
The 380 SL used an aluminum V8 and the R107 body that Mercedes built for nearly two decades. Its hardtop, soft top and solid construction have made it a favorite open car for touring.
Before You Install
Bolts are not supplied for the 380 SL pair, so check that the original fasteners are in good shape. Inspect the anchor points and retractor mounts before fitting.
Good to Know
Two front belts.
Both belts are made from one dye lot.
End release buckles are easy to use with the top up or down.
New straps are a pleasing upgrade for a fair-weather SL.
Retractors keep the straps tidy when the car is parked.
The 380 SL's cabin is snug, and reel-type belts with end-release buckles give both people room to move.
The R107 was built from 1971 to 1989, and the 380 SL is one of the most common versions in North America.
Both belts come from the same dye lot.
End release buckles are easy to use with the top up or down.
New straps are a pleasing upgrade for a fair-weather SL.
In an open car like the 380 SL, belts are exposed to sun and weather whenever the top is down. Over time this fades and weakens the webbing. A new pair restores strength and color, and darker shades tend to hold up better in sunny climates.
The 380 SL is a car many owners keep for decades, and fresh belts are part of that long-term care. Choose a color that suits your car's leather or MB-Tex upholstery.
Because hardware is not included, check the condition of the original bolts before you start.
The 380 SL carried a 3.8-liter V8 and was sold in North America through 1985 before the 560 SL replaced it, although Seatbelt Planet lists this kit through 1986.
Retractors keep the belts tidy and out of the way when the car is parked with the top down.
A freshly belted 380 SL feels ready for long touring days.
