Bilstein 5100 Series 86-89 Toyota 4Runner / Pickup Rear 46mm Monotube Shock Absorber

The 46mm monotube design in these Bilstein B8 5100 rear shock absorbers means they can handle tough conditions without losing effectiveness. This is a direct fit for your 1984-1989 Toyota 4Runner or 1986-1995 Toyota Pickup, especially if you've lifted it. The monotube construction helps dissipate heat, so you get steady performance whether you're on the highway or tackling rougher terrain.

What really sets these shocks apart is the patented digressive piston. It's velocity-sensitive, meaning it adjusts automatically to how quickly the suspension is moving. So, on smooth roads, it's comfortable, but when you hit a bump or need to react quickly, it stiffens up to control the movement. Bilstein tunes each shock specifically for your vehicle, so you can expect an improved ride quality and better handling compared to stock shocks.
