The Bilstein B6 24-011419 is a rear monotube shock from the B6 4600 family, built for the Chevrolet G30 full-size van and sold as a single replacement unit. Bilstein positions the B6 4600 line as a direct-fit upgrade over factory dampers on stock-height light trucks. Its velocity-sensitive digressive piston is designed to respond to changing road input, and the monotube layout is meant to keep damping consistent under repeated hard use rather than fading as the shock heats up.
Owners on user forums who have run B6 units on one-ton G30 vans say they like them, pointing to firmer, better-controlled body motion when the van carries a load. Expect a firmer feel than the factory dampers, especially when the van is empty, so this upgrade suits a work van, camper, or heavy-cargo hauler better than a lightly loaded daily driver. The case for paying more is control under weight, not a softer ride. This part is applied to dual rear wheel axles, so a buyer running a single-wheel G30 needs to confirm a different shock before ordering. Searches for 1975-1995 Chevy G30 dual rear wheel shock, Bilstein B6 4600 monotube van, and heavy-duty G30 camper rear shock tend to land on this exact application.
No. Fitment is for the dual rear wheel axle. Owners on user forums report that the single-wheel shock is shorter, so using the dual-wheel part on a single-wheel van is not a safe substitute.
Sources do not agree on the year range. Some list 1975-1995 and others list 1975-1996, and the application can vary with the van's configuration. Check your VIN and rear axle setup, and confirm with the manufacturer before ordering.
The manufacturer lists the B6 4600 line as non-adjustable, so damping is set at the factory and cannot be changed by the owner.
This is a manageable driveway job for someone comfortable with basic hand tools, a floor jack, and jack stands. Owners on user forums describing B6 rear installs on other trucks say the top nut can be hard to reach, so a helper makes the job easier. Supporting the frame or axle on stands with the wheels off lets the suspension unload so the bolts come free. Owners also note that gas-charged Bilstein shocks often need to be compressed with a jack to line up the lower mount, and that lubricating the eye and seating the lower mount first can help. If the van has a lift or leveling kit, expect more difficulty starting the top nut without load on the suspension. Confirm that you have the dual rear wheel part before you start.
