Part Number: 013-108-03
This equalizer is designed for trailer suspension systems using 3" wide slipper springs on tandem or triple axle configurations. It is commonly used on 10,000–15,000 lb axle applications to distribute suspension load and maintain balanced axle movement.
Common Applications
- Tandem axle heavy-duty equipment trailers
- Triple axle deck-over trailers
- High-capacity utility trailers
- Suspension rebuilds on 3" slipper spring systems
Features
- Designed for 3" wide slipper spring suspension systems
- Common on 10K–15K axle configurations
- Non-side-specific equalizer design
- Heavy-duty steel construction
- Compatible with standard heavy-duty equalizer hardware
R&P Knowledge Hub
In slipper spring suspension systems, the equalizer pivots at the center bolt to transfer road shock between axles. When one axle encounters uneven terrain, the equalizer rotates to distribute force across the adjacent axle.
Equalizer length directly determines axle spacing and suspension geometry. Always confirm spring width, bolt diameters, and center-to-center measurements before installation.
