The Bilstein B8 Performance Plus 24-015370 is a front monotube gas-pressure shock absorber listed for the 1992 Mercedes-Benz 300SD base model. The manufacturer presents the B8 Performance Plus as a performance step up from OE dampers, with application-specific valve settings, and intends it to pair with aftermarket lowering springs. Because it is a shortened damper for lowered setups, a driver who wants to keep factory ride height should look at Bilstein's B6 line instead.
Compared with a worn stock unit, this shock gives a firmer, more controlled response once the car has been lowered, and the manufacturer states each damper is tested to meet or exceed OE standards. Bilstein backs the B8 series with a limited lifetime warranty. Fitment deserves care before you buy. Published application lists disagree on whether 300SE, 400SE, 500SEC, 500SEL or S-Class models share this part number, so confirm your exact model year and chassis with the manufacturer. Enthusiasts searching for a lowered 300SD front shock, a Bilstein B8 Performance Plus monotube damper, or part 24-015370 will find this a direct OE-style replacement for the front axle.
No. The manufacturer designs the B8 Performance Plus for use with lowering springs or sport springs. It is a shortened damper, so it is not intended for an OE-height setup. For a stock-height car, Bilstein's B6 line is the matching choice.
Yes. The manufacturer's install notes recommend replacing shock absorbers in pairs, passenger and driver side together, so both sides ride the same.
Yes. Published application lists for this part number are not consistent across models and years. Confirm your exact Mercedes model, model year and chassis with the manufacturer before ordering.
Front replacement is a moderate-difficulty job. Owners on user forums report that the lower bolts are reached most easily with the wheel removed, that a thin-wall 12-point 10mm socket is the common tool for those bolts, and that the upper stem nut needs the stem held while you loosen it. One forum owner describes the front setup as one bolt on top and two on the bottom. The manufacturer's general instructions say Bilstein suspension components require special tools and expert knowledge, should be installed by a qualified suspension specialist on a chassis hoist, and need a caster and camber check plus headlight and brake system checks after the job. If you lower the car, also confirm that the wheels and tires have full clearance through the suspension's travel.
