The Bilstein 5100 shocks set is a high-performance suspension upgrade designed for 4WD vehicles with a 3-4 inch lift. Featuring a monotube design with a 46mm digressive piston, these shocks provide improved handling both on and off-road. Constructed with a zinc-plated finish for corrosion resistance, they effectively dissipate heat to reduce shock fade and enhance durability. The shocks are extended length to accommodate lifted suspensions, reducing body roll and nose dive while offering increased compliance over bumps and rough terrain. Backed by a limited lifetime warranty, they are built for demanding off-road conditions, heavy-duty loads, and towing, ensuring long-lasting performance and reliability.
These shocks are specifically designed for 1973-1987 GMC K15 4WD models with factory hardware included for straightforward installation. Reusing factory shock mounting bolts, the kit contains four shocks—two front and two rear—compatible with vehicles equipped with larger tires or lifted suspensions. Suitable for vehicles with 3-4 inch lifts, these shocks are ideal for off-road enthusiasts and daily drivers seeking enhanced ride quality and stability. Note that factory spec vehicles should opt for Bilstein 4600 series shocks, as the 5100 series is optimized for lifted and off-road applications. Mounting plates are sold separately.

[Blog Post: Bilstein 5100 vs. 4600, Major Differences](https://www.shocksurplus.com/pages/bilstein-4600-vs-5100-series-the-lowdown)
Bilstein 5100 shocks utilize a monotube design, with a 46mm digressive piston, to increase road handling characteristics both on and off-road. The single tube body allows for rapid heat transfer between the shock oil to the shock body, and then dissipated further to reduce shock fade. German engineering combined with US manufacturing ensures optimum performance and longevity for upwards of 100k miles (real customer feedback!). The 5100 series is more compliant in tougher situations and off-road terrain compared to the 4600 series. Factory spec vehicles should use the 4600 series shocks as the valving is more appropriate for daily driven vehicles and pavement environments.
