Yukon Gear Dana 30 & Dana 44 Power Lok Bolt / Left Hand / & 8.75in Chrysler & 55P

Left-Hand Thread Ring Gear Bolt for Dana 30, Dana 44, Chrysler 8.75in, and 55P Differentials

The Yukon Gear YUKYSPBLT-052 is a left-hand threaded ring gear bolt for Dana 30, Dana 44 Power Lok, 8.75-inch Chrysler, and 55P differential assemblies. Left-hand thread ring gear bolts are used in applications where the ring gear's rotation direction would cause a standard right-hand bolt to back out under load. This bolt is manufactured to OEM-equivalent thread engagement and clamping force specifications, keeping the ring gear securely fastened to the carrier under towing, off-road, and high-load conditions. Using the correct thread direction on ring gear bolts is not optional.

Key Features

• Left-hand thread prevents self-loosening in differential applications that require it
• Fits Dana 30, Dana 44 Power Lok, 8.75in Chrysler, and 55P differential assemblies
• OEM-equivalent thread engagement and clamping force for secure ring gear fastening
• Manufactured to tight dimensional tolerances for consistent torque values
• Compatible with Yukon ring and pinion sets for complete differential rebuilds
• Lifetime Limited Warranty from Yukon Gear and Axle

What's Included

• 1x Yukon Gear left-hand ring gear bolt for Dana 30, Dana 44 Power Lok, Chrysler 8.75in, and 55P differentials

Frequently Asked Questions

Why does this ring gear bolt use left-hand threads?
In certain differential configurations, the ring gear rotates in a direction that would cause standard right-hand thread fasteners to back out during operation. Left-hand threads tighten with ring gear rotation rather than loosening, keeping the ring gear securely fastened under load.

How do I tell if my differential uses left-hand or right-hand ring gear bolts?
Attempt to turn a bolt counterclockwise. If it tightens, it is a left-hand thread bolt. Dana 30, Dana 44 Power Lok, Chrysler 8.75in, and 55P differentials use left-hand threads. Verify your specific differential before ordering.

How many ring gear bolts does a Dana 30 or Dana 44 use?
Dana 30 and Dana 44 ring gears typically use ten bolts. Order accordingly for a complete set replacement. Verify the bolt count by inspecting your ring gear carrier before ordering.

Can I mix old and new ring gear bolts when doing a ring and pinion swap?
No. Always replace all ring gear bolts at once when installing a new ring gear. Used bolts that have been torqued may be stretched, and mixing hardware creates uneven clamping force across the ring gear face.

What torque spec applies to left-hand ring gear bolts?
Torque specification varies by differential model and application. Refer to the factory service manual for your specific axle. For Dana 30 and Dana 44 applications, ring gear bolt torque is typically in the 55-80 ft-lb range.

Is thread-lock compound used on ring gear bolts?
This depends on the manufacturer's specification. Some Dana applications use thread-lock, while others rely on correct torque alone. Follow the factory service manual recommendation for your specific differential.

What warranty does Yukon provide on ring gear hardware?
Yukon covers the YUKYSPBLT-052 with a Lifetime Limited Warranty. Drivetrain components qualify for consumer protections under the Magnuson-Moss Warranty Act.

Does this bolt also fit non-Power Lok Dana 44 carriers?
The listing specifies Dana 44 Power Lok. Standard open and other carrier types may use a different bolt specification. Verify your carrier type before ordering to ensure you are purchasing the correct bolt.

Installation Notes

• Remember that left-hand threads tighten counterclockwise; use a torque wrench rated for your application
• Replace all ring gear bolts as a set, never mix old and new hardware
• Clean bolt holes in the carrier of any debris or old thread-lock compound before installation
• Apply thread-lock compound if specified by the factory service manual for your differential
• Torque in a star pattern to factory specification to ensure even ring gear seating
