Ferrari & Maserati Shock Absorber Silent Block Bush Pair 157630 – Front Suspension

Premium Shock Absorber Silent Block Bush Pair – Part 157630

Restore controlled suspension movement and reduce unwanted vibration with this replacement shock absorber silent block bush pair, reference 157630. This long-running Ferrari and Maserati suspension reference is used across a wide range of performance and grand-touring models, including Ferrari 458, 488, 550 and 575 applications as well as Maserati Quattroporte, GranTurismo and related platforms.

Material & Construction

Each bushing uses a cylindrical steel outer sleeve surrounding a bonded elastomer isolation core and reinforced metal inner sleeve. This multi-material construction allows the suspension joint to articulate under load while controlling noise, vibration and harshness. The steel shell provides a stable press-fit interface, while the rubber isolation layer absorbs movement between the shock absorber and suspension mounting point.

What It Does

• Provides a controlled pivot point at the shock absorber mounting location.
• Helps isolate road vibration before it transfers into the chassis.
• Maintains stable shock absorber positioning during compression and rebound.
• Replaces hardened, split or loose bushings that can contribute to suspension knocking and imprecise movement.

Why Replace in Pairs?

Suspension bushings on the same axle operate under similar loads and heat cycles. Replacing them as a pair helps maintain balanced compliance and damping behavior from left to right.
