Description
Secure your trailers wheel-end assembly with the commercial-grade 27-064 Spindle Nut, distributed specifically for heavy-duty fleet operations like Sun Country Trailers. This low-profile hex jam nut acts as the foundational anchor for your trailers hub assembly, securing wheel bearings firmly to the spindle axis. Cross-referenced under factory part number 8750008 (and Dexter 006-084-00), it provides the relentless clamping power required to eliminate hub play, lock in critical bearing pre-loads, and prevent unexpected hub detachment over thousands of high-capacity highway miles.
Key Features & Technical Specs:
Exact Industry Cross-Reference: Directly replaces factory part numbers 8750008, Dexter 006-084-00 (6-84), and fits standard Traction SKU 27-064 specifications.
Heavy-Duty Spindle Size: Standard 1-3/4 inch (1.75") inner diameter with precision-machined 1-3/4"-12 fine threads for an exact, non-slip fit on commercial spindles.
Low-Profile Jam Nut Style: Engineered with a compact hex profile designed specifically to fit into closed trailer oil caps and grease caps without rubbing.
Axle Application: Explicitly rated for commercial-grade trailer axles ranging from 10,000 lbs. to 15,000 lbs. load capacities.
Sun Country Commercial-Grade: Premium build tolerances sourced to withstand continuous braking heat, road salt exposure, and heavy structural vibration.
Maintenance & Installation Best Practices:
For total wheel-end safety, this low-profile jam nut should always be configured alongside a fresh Sun Country Spindle Washer (8750042 / 27-063) and a matching 1-3/4" Tang Lock Washer (8750041 / 27-065). Never over-torque the spindle nut, as over-tightening compresses the inner wheel bearings, leading to localized hub friction, premature grease breakdown, and bearing burnout.
