Overview
This tandem axle shackle and hanger kit is a complete suspension hardware refresh package for compatible trailers using long equalizers, 2" center-to-center shackle straps, and 1-3/4" wide leaf springs. The kit includes the main wear-point hardware commonly replaced during tandem axle suspension service, including equalizers, shackle straps, shackle bolts, lock nuts, and front, rear, and center hangers.
R&P Service Insight
Trailer suspension hardware should be matched by measurement, not by appearance alone. Equalizer length, hanger height, shackle length, and bolt diameter all affect axle spacing and suspension movement.
- Measure First: Confirm the existing equalizer length and shackle strap center-to-center measurement.
- Check Hanger Height: Front, rear, and center hanger dimensions must match the suspension layout.
- Replace as a System: Worn shackles, bolts, and equalizers often wear together, making a full kit a cleaner service option.
R&P Knowledge Hub
Compatibility: Designed for compatible tandem axle leaf spring suspension systems using 1-3/4" wide springs, 7-3/4" long equalizers, and 2" center-to-center shackle straps.
System Fit: Commonly used on tandem axle utility trailers, cargo trailers, equipment trailers, and similar spring suspension builds where the hanger and equalizer geometry matches.
Installation Notes: Verify axle spacing, hanger placement, equalizer length, bolt size, and shackle length before removing the existing suspension hardware.
Performance Insight: Correct suspension geometry allows the equalizers and shackles to move properly as trailer load shifts between axles. Incorrect hanger or shackle dimensions can affect ride height, axle spacing, and spring travel.
Brand & Fitment Note

R&P Repair Insight
Suspension rebuild kits are measurement-sensitive. The safest way to confirm fit is to compare the existing trailer hardware against the dimensions listed in this product description.
- Equalizer Check: Confirm the trailer uses 7-3/4" long equalizers before ordering.
- Shackle Check: Confirm the current straps measure 2" from hole center to hole center.
- Hanger Check: Confirm the center hanger and front/rear hanger bolt heights match the trailer layout.
