Overview
This R&P Carriages SRK-TA-WB-104-2 tandem axle suspension rebuild kit brings together the key wear-service components commonly replaced during trailer suspension repair. The kit includes greaseable wet bolts, 7/16" flanged nuts, 2" shackle straps, nylon bushings, and two 13-104 short equalizers for compatible tandem axle suspension setups.
R&P Service Insight
Tandem trailer suspension parts should be checked as a system. Worn bushings, loose shackles, damaged equalizers, or tired bolt hardware can create noise, uneven movement, and poor suspension tracking.
- System Refresh: Includes equalizers, shackle straps, bushings, wet bolts, and flanged nuts.
- Greasable Hardware: Wet bolts support service lubrication when installed and maintained correctly.
- Measure First: Match your current equalizer, shackle, bushing, and bolt dimensions before ordering.
R&P Knowledge Hub
Compatibility: Intended for compatible tandem axle trailer suspension applications using 13-104 / EQ-104 style short equalizers, 2" shackle straps, 8137 nylon bushings, FA-7-187 greaseable wet bolts, and FA-6-92Z 7/16" flanged nuts.
Vehicle / System Fit: Tandem trailer suspension systems where the existing equalizer profile, shackle length, bushing dimensions, wet bolt size, and mounting points match the listed components.
Installation Notes: Confirm hanger spacing, equalizer dimensions, shackle strap length, bolt diameter, thread length, and bushing fit before installation.

R&P Repair Insight
Before installing a tandem trailer suspension rebuild kit, inspect both sides of the suspension for worn shackles, elongated bolt holes, cracked or damaged equalizers, and bushing wear. Similar-looking trailer suspension parts can use different lengths and hole sizes, so measurement confirmation is the safest way to verify fit.
- Equalizer Check: Confirm the existing equalizer matches the 13-104 short equalizer style and 5.6" length.
- Shackle Check: Confirm 2" hole-center shackle straps with the listed 3.187" x 1.25" x 0.23" overall dimensions.
- Bushing / Bolt Check: Confirm 8137 nylon bushing dimensions and FA-7-187 7/16" x 3" wet bolt compatibility.
