Tandem trailer suspension parts work as a system. Worn equalizers, loose shackles, damaged bushings, or tired bolt hardware can cause noise, uneven movement, and poor suspension tracking. Replacing the wear components together helps keep the suspension service consistent side to side.

R&P Repair Insight
Before replacing tandem trailer suspension hardware, inspect both sides of the suspension for worn shackles, elongated bolt holes, cracked or damaged equalizers, and bushing wear. Trailer suspension parts can look similar but use different dimensions, so matching the existing hardware is the safest way to confirm fit.
- Equalizer Check: Confirm your existing equalizer matches the EQ-104 / 13-104 style before ordering.
- Shackle Check: Verify the 2.562" shackle strap length against your current suspension.
- Hardware Check: Confirm wet bolt and 7/16" flange nut compatibility with your suspension before installation.
