Fit Details
Listed for the driver and passenger of 1972-1974 Mercedes 450 SL roadsters.
Color Choices
This kit is offered in black webbing only, a classic, understated choice that suits almost any SL interior.
Time for New Belts?
Roadster belts take more sun than those in a closed car, so originals often fade and stiffen. Fresh retractable lap belts restore smooth operation and a firm latch for both occupants.
Caring for Your Belts
Use a cover outdoors.
About the Mercedes-Benz 450 SL
The 450 SL was part of Mercedes' R107 roadster series, introduced in the early seventies and built for many years. These two-seaters combined a V8, a removable hardtop and a soft top with solid build quality, and they remain some of the most popular classic Mercedes models today.
Pre-Install Checklist
Source bolts.
Good to Know
Hardware not included.
Seatbelt Planet rates the 450 SL kit to FMVSS 209 and 302.
Black is the only webbing color Seatbelt Planet makes for this kit, so both belts arrive matched and ready to blend with the roadster's cockpit.
Bring your own bolts for the 450 SL, since none are supplied, and check each anchor.
Retractable two-point lap belts keep the straps tidy in a small roadster cabin.
End release buckles are simple to use and familiar to modern passengers.
The 450 SL was part of the R107 SL roadster series, which stayed in production for many years and remains popular with collectors.
Roadster interiors take a beating from sun, so a cover or the hardtop helps protect new belts.
Wash the roadster straps gently and air-dry them.
These roadsters are prized for their build quality and timeless styling.
Fresh belts help the cabin look as good as the bodywork.
Both belts come in one kit.
Many 450 SLs are driven regularly, and dependable belts suit that use.
Classic Mercedes owners value correct details, and belts are part of that.
The R107 roadster was sold for many years with only gradual changes, and its long run means plenty of cars survive for enthusiasts to enjoy today.
Seatbelt Planet's listing title says driver and passenger, and the kit covers both seats with retractable lap belts.
Retractable lap belts keep the cockpit uncluttered and stop loose webbing from rubbing the console or door panels.
Order the kit and give both seats of the roadster fresh belts in one step.
The 450 SL remains a favorite top-down cruiser, and fresh belts complete its cockpit.
Order now for the next sunny weekend.
Black webbing pairs neatly with the dark dash and console trim found in many of these early R107 cars.
