Four-piece trailer suspension hardware kit with 9/16" shackle bolts and matching lock nuts for common leaf spring hanger and equalizer service work.
This R&P Carriages trailer shackle bolt and lock nut kit includes four 9/16" shackle bolts with matching lock nuts for common trailer leaf spring suspension service. These components are typically used in spring hanger, shackle, and equalizer assemblies where the original hardware is worn, missing, or being replaced during suspension repair.
Suspension bolts and lock nuts are small parts, but they carry real load through the spring and equalizer system. Replacing worn hardware during spring or equalizer service helps restore a tighter, more secure suspension connection.
Compatibility: Designed for trailer suspension applications that use 9/16" shackle bolts.
Vehicle / System Fit: Commonly used with double-eye leaf spring hanger, shackle, and equalizer assemblies.
Installation Notes: Verify bolt diameter, bolt length, hanger style, equalizer configuration, and bushing size before ordering or installing.
Performance Insight: Correct suspension hardware helps maintain proper spring and equalizer movement while keeping the assembly securely fastened.
Selling Brand: R&P Carriages
Application Reference: This listing is for trailer suspension hardware commonly used in compatible leaf spring hanger and equalizer assemblies where the measurements match.
What This Means: This is a curated R&P Carriages hardware kit, not a guaranteed OEM-branded item unless specifically stated and verified.
Before Ordering: Confirm the bolt diameter, length, thread style, suspension position, and included components against your existing trailer hardware.
When trailer suspension hardware is loose, worn, or seized, it can make spring and equalizer service harder than it needs to be. Replacing bolts and lock nuts during repair is often cleaner than trying to reuse hardware that has already been under load.
Includes four shackle bolts and four matching lock nuts for trailer suspension service.
Built for applications requiring 9/16" trailer shackle bolts.
Commonly used in front and rear spring hanger locations, shackles, and equalizer assemblies.
