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.

-
Shackle Check: Verify the 2.562" shackle strap length against your current suspension.
