Bilstein 4600 Series Shock Absorber | Fits 1999-2004 F250/F350/F450/F550 Super Duty

Heavy-duty trucks carrying serious loads need shocks that won't fade partway through a haul. The 4600 Series uses a monotube body and gas pressure charge that keeps the oil from foaming, so damping stays consistent whether you're loaded up or running empty.

• Fits 1999-2004 F250, F350, F450, and F550 Super Duty trucks up to 15,000 lbs GVWR
• Monotube design delivers fade-free performance
• Gas pressure technology prevents oil foaming for reliable damping
• Consistent control across a range of driving and load conditions
• Durable materials resist corrosion and wear over time

A direct upgrade path for Super Duty owners who tow or haul regularly and want steadier control.
