Product Details

This Monroe Load Adjusting Shock Absorber line is built for vehicles that see changing payloads, trailer use, or uneven rear suspension demand. Monroe 58646 adds spring-assisted support to the shock absorber design so the rear suspension can maintain more consistent control when the Jeep Commander or Jeep Grand Cherokee is carrying cargo or towing. This part cross-references KYB (e.g., 349230, 554377) for the same application.

What It Helps Address

• Rear-end sag when towing or hauling
• Excessive bounce after load changes
• Reduced control over rough or uneven roads
