Is the Bilstein B4 an upgrade or a standard replacement?
Is the Bilstein B4 an upgrade or a standard replacement?
The Bilstein B4 is designed specifically as an Original Equipment (OE) replacement shock absorber. It is intended to restore your vehicle’s factory‑standard ride quality and safety. While it utilizes superior materials compared to many generic aftermarket shocks, it is not a “stiff” performance upgrade; instead, it provides the precise, comfortable feel your car had when it was brand new.
Are Bilstein B4 shocks gas-pressure or oil shocks?
Are Bilstein B4 shocks gas-pressure or oil shocks?
The Bilstein B4 utilizes Bilstein’s famous gas‑pressure technology. Unlike standard oil‑only shocks that can “foam” or fade under heavy use, the B4 features a gas charge that keeps the oil under pressure. This prevents aeration and ensures consistent damping performance, even under high stress or in extreme temperatures.
Should I choose Bilstein B4 or Bilstein B6?
Should I choose Bilstein B4 or Bilstein B6?
If you want to maintain the comfortable ride quality specified by your vehicle’s manufacturer, choose the B4. If you frequently carry heavy loads, tow a trailer, or want a noticeably firmer, sporty handling experience without lowering the car, choose the B6.
Can I install Bilstein B4 shocks if my car has lowered springs?
Can I install Bilstein B4 shocks if my car has lowered springs?
The Bilstein B4 is designed to work with your vehicle’s standard ride height and standard‑length springs. If your vehicle has been significantly lowered using performance springs, we recommend choosing the Bilstein B8 series, which is specifically shortened and valved to handle the increased tension of lowering kits.
