ICON Vehicle Dynamics 56104 Air Bump Stop Travel - Rear Kit for Toyota 4Runner FJ Cruiser Lexus GX

The ICON Vehicle Dynamics 56104 Rear Air Bump Stop Kit transforms the off-road performance of your Toyota 4Runner, FJ Cruiser, or Lexus GX by replacing ineffective factory rubber bump stops with velocity-sensitive hydraulic technology. This bolt-in upgrade dramatically reduces harsh rear-end kick and improves control over rough terrain without sacrificing suspension travel.

Key Features:

• Hydraulic/pneumatic bump stop technology significantly increases bump energy absorption capacity

• Installs easily inside the factory coil spring with no modification required
• Fully rebuildable and tunable for custom ride characteristics
• Maintains full factory suspension travel while improving bottom-out resistance
• Bolt-in installation with all necessary hardware included

Performance Benefits:

• Dramatically improved off-road handling and comfort over rough terrain
• Reduces chassis upset and loss of control during aggressive driving
• Protects suspension components from harsh bottom-out impacts
• Enhanced driver confidence in challenging off-road conditions
