This Bilstein 24-011785 is a 46mm monotube rear shock listed for the 1988 Chevrolet Corvette 35th Anniversary Edition, a C4-generation car. Its monotube, gas-pressure body is built to resist the heat buildup that can fade twin-tube units under hard driving. Over a worn or budget replacement, a valved Bilstein damper restores firm body control on broken pavement and through quick direction changes. Searches for this part usually include terms like 1988 Corvette 35th Anniversary rear shock, C4 Corvette gas-charged rear monotube, and Bilstein rear shock upgrade.
The series choice matters more than the brand. The manufacturer says its B6 is sized for stock-height springs and its B8 is intended for lowered cars, so match the series to your ride height. Sources conflict on which series this part number carries, with some labeling it B6 and others B8 Performance Plus, so confirm the series with the manufacturer before ordering. Owners on user forums who fitted the B8 version of this number to a 1994 Corvette reported its length matched the originals they removed. Fitment listings also differ on whether the part suits only Z51-equipped cars or base cars too, so check your car's suspension package. The manufacturer also states that B6 dampers can be fitted rear-only, which suits owners who want firmer rear damping without changing the front.
