Bilstein B6 1989 Porsche 944 Base Rear 36mm Monotube Shock Absorber - 24-020527

• Improved safety and performance without the requirement of new springs (use of series spring possible)
• Optimum grip and enhanced lane stability in day to day and extreme situations
• Bilstein gas-pressure technology
• Vehicle Specific Ride Tuning

The Bilstein B6 24-020527 is a 36mm monotube rear shock absorber engineered specifically for the 1989 Porsche 944 Base. As a direct OE-replacement performance upgrade, the B6 is Bilstein's answer for drivers who want noticeably sharper damping response and longer service life compared to worn or budget-replacement shocks — without abandoning street manners. If your 944's rear end feels floaty, wallows through corners, or simply has high-mileage shocks that have given up, the B6 is the purpose-built solution.

Key Features & Benefits

• 36mm Monotube Design: Bilstein's signature large-diameter monotube construction separates the oil and gas charge into a single tube, delivering more consistent damping force and better heat dissipation than twin-tube alternatives — critical on a sports car like the 944 where rear suspension geometry is already finely tuned.
• Velocity-Sensitive Damping: The B6's internal valving is calibrated to respond progressively to road inputs. Light, high-frequency bumps are absorbed comfortably while aggressive inputs — hard cornering loads, abrupt lane changes — are met with firmer, more controlled resistance. This means improved body control without a punishing ride.
• Direct OE Fitment: Designed to bolt directly into the 1989 Porsche 944's existing rear suspension mounting points. No cutting, welding, or modification required — a straightforward replacement job for any competent home mechanic or shop.
• Bilstein's Proven Monotube Technology: Bilstein pioneered the gas-pressure monotube shock absorber and has supplied OE dampers to Porsche from the factory for decades. The B6 line carries that same engineering heritage into the performance aftermarket segment.
• Fade-Resistant Performance: The separated gas and oil chambers prevent the aeration (foaming) that causes conventional twin-tube shocks to fade under repeated hard use. This makes the B6 a strong choice for 944 owners who enjoy spirited back-road driving or occasional track days.
• Long Service Life: Bilstein shocks are manufactured to tight tolerances with quality seals and hardened components, helping the B6 outlast budget replacements and hold its damping characteristics over time.

Frequently Asked Questions

What years and trims of the Porsche 944 does part number 24-020527 fit?

Based on the product data, this Bilstein B6 rear shock is confirmed for the 1989 Porsche 944 Base. It is not confirmed for other 944 variants (S, S2, Turbo) or other model years without additional verification. Contact us with your VIN or trim level if you're unsure.

Is the Bilstein B6 a direct bolt-on replacement for the stock rear shocks on the 944?

Yes — the B6 24-020527 is engineered as a direct OE-replacement shock for the 1989 Porsche 944 Base rear position, meaning it is designed to use the factory mounting hardware and suspension geometry without requiring modifications.

How does the Bilstein B6 differ from the stock shocks on my 944?

The B6 uses Bilstein's 36mm monotube gas-pressure design, which provides more consistent damping, better heat management, and improved body control compared to typical worn or entry-level twin-tube replacement shocks. Drivers generally notice better cornering composure and a more planted rear end with the B6 installed.

Do I need to buy a pair, or is this listing for a single shock?

Part number 24-020527 is for a single rear shock absorber. If you are replacing both rear shocks — which is generally recommended for balanced handling — you will need to add two units to your order. Contact our team if you have questions about ordering multiples.
