Product Details

The Monroe Gas-Magnum Shock Absorber line is engineered for heavier-duty truck and van suspension demands, using increased fluid capacity to improve control and reduce effort during compression and rebound. Monroe 34958 is a practical choice for restoring ride stability on older Jeep and Ford platforms where consistent damping matters, including Jeep Grand Wagoneer and Ford Bronco rear shock applications. This part cross-references KYB 344087 for the same application.

Common Problems This Shock Can Address

• Excessive bouncing after bumps or dips
• Reduced body control during braking and cornering
• Rear-end instability on loaded trucks and vans
• Uneven ride quality from worn suspension damping
• Noise or harshness caused by aging shock absorber internals
