Protect your trailer (and your cargo!) with Equa-Flex!

Towing a trailer shouldn’t feel like riding a bucking bronco. Yet many owners experience constant bouncing, fore-and-aft “chucking,” and excessive vibration that fatigues the driver and stresses the trailer and its contents. The culprit is often the standard rigid equalizer in the leaf spring suspension.

The Problem with Traditional Equalizers

Conventional cast or steel equalizers transfer every road imperfection directly through the suspension. This leads to harsh ride quality, accelerated wear on leaf springs, tires, and cargo, plus driver fatigue on long hauls. For RV owners, boat haulers, and heavy equipment operators, this constant pounding shortens component life and increases the risk of damage.

The Equa-Flex Solution from Lippert

The Lippert Equa-Flex Rubberized Equalizer replaces traditional equalizers with a patented rubberized design. Dual-pivoting arms with pre-installed bronze bushings and high-performance rubber cores absorb and dampen road shock before it reaches the trailer frame. The result is a noticeably smoother, quieter, and more stable towing experience.

Available Equa-Flex Kits

Southwest Wheel stocks multiple configurations to match your setup:

• Tandem Axle Kit (4,000-6,000 lb axles) – #2024114953
• Tandem Axle Heavy-Duty Kit (6,000-8,000 lb axles) – #2024115051

• Short Triple Axle Kit (5,000-8,000 lb axles) – #2024115101

Key Features and Benefits

• Rubberized Cushioning: Dramatically reduces fore-and-aft trailer movement and road shock.
• Dual-Pivoting Arms: Allow independent movement for better weight distribution between axles.
• Pre-Installed Bronze Bushings: Improve durability and smooth operation over time.
• Sturdy Construction: Heavy-duty steel with black powder coat finish and zinc-plated fasteners for excellent corrosion resistance.
• Bolt-On Installation: No drilling or welding required — perfect for DIY or professional installers.
• Reduced Cargo Damage: Smoother ride means less stress on delicate loads, appliances, and equipment.

Real-World Performance Advantages

Owners report significantly less chucking when pulling over expansion joints, railroad tracks, or rough country roads. The rubber elements act like built-in shock absorbers, delivering ride comfort that rivals far more expensive air-ride or torsion axle systems.

Ideal Applications

The Equa-Flex system excels on travel trailers, fifth-wheels, boat trailers, horse trailers, equipment trailers, and commercial fleet vehicles.

Installation and Maintenance Tips

• Installation is straightforward bolt-on — suspension mounting kits sold separately.
• Check all fasteners after the first 100 miles and periodically thereafter.
• Inspect rubber elements for wear during annual trailer service.
• Pair with quality leaf springs and U-bolt kits for a complete suspension refresh.
