Bilstein 24-144780 Performance Shock Absorbers - Heavy Duty Yellow Off-Road Suspension for Trucks, SUVs & Jeeps - Perfect for Rough Terrain & Adventure Driving

My rear suspension was sagging and any slight bump I went over was jarring and made horrible noise. The police cars have Nivomat shocks and thus the standard R/T shocks do NOT work and can't be used (don't let anyone tell you otherwise). So you're stuck buying expensive Nivomats that you probably don't need or these which are about half as expensive as the Nivomats. Ride quality is great with these and going over bumps is much smoother and quieter though the car still handles plenty aggressively.
