Buyer’s Guide: What to Consider
Choosing the right trailer suspension depends on your trailer type, load, and towing conditions. Here are five key factors to consider before buying.
- Load Capacity: Match the suspension's weight rating to your trailer's gross vehicle weight rating (GVWR) to ensure safe towing.
- Axle Compatibility: Check your axle diameter and type (round or square) to ensure U-bolts and hardware fit correctly.
- Leaf Spring Count: More leaves generally mean higher capacity but a stiffer ride. Choose based on your typical load.
- Installation Ease: Look for kits with all hardware included. Some require specific tightening procedures, so read instructions.
- Suspension Type: Decide between full leaf spring kits, equalizer upgrades, or lockouts based on your trailer and towing needs.
