Gabriel Load Carrier Shocks – Spring Assist for Towing

The Gabriel Load Carrier shocks combine a shock absorber with a variable-rate coil spring to help your truck handle the extra weight of a 5th wheel. They provide up to 500 lbs of load support per pair, which reduces ride height loss and keeps your vehicle more stable while towing or hauling. This is especially useful if you notice sagging in the rear when you hook up your trailer.

Built with a drawn-over-mandrel pressure cylinder, these shocks resist internal wear and last longer under heavy use. The chromed piston rod fights corrosion and maintains a consistent seal, while the leak-proof piston seal helps extend the shock’s life. If you drive a compatible Chevrolet, GMC, Dodge, Jeep, or Nissan truck, these spring-assist shocks are a practical upgrade for towing.

Buyer’s Guide: What to Consider

Choosing the right shock for towing a 5th wheel depends on your truck, trailer weight, and driving conditions. Here are five key factors to consider before making a purchase.

• Vehicle Compatibility: Ensure the shock or hitch matches your truck's make, model, and bed length. Check for specific requirements like a puck system or pin box type.
• Load Capacity: Consider the weight of your 5th wheel. Shocks with spring assist can support up to 500 lbs, while pin box replacements are rated for 18K or 24K.
• Corrosion Resistance: Look for coatings like powder coating or salt-spray ratings (e.g., 300 hours) if you drive in wet or salty conditions. This extends the product's lifespan.
• Installation Ease: Some products are direct replacements or come pre-assembled, saving time. Others may require specialty tools or professional installation.
• Ride Quality vs. Stability: Stiffer shocks improve stability when towing but may feel firmer when unloaded. Balance your need for control with everyday comfort.

Conclusion

Upgrading your shocks or hitch can make a noticeable difference in how your truck handles a 5th wheel trailer. Whether you need a direct pin box replacement, spring-assist shocks, or a hitch with built-in shock suppression, each product here addresses a specific need.

For most owners, the CURT Helux replacement shock is ideal if you already have that pin box. If you’re dealing with rear sag, the Gabriel Load Carrier shocks are a solid choice. And for a complete system upgrade, the CURT A25 hitch offers integrated shock control.
