Rock Krawler RK00009L Jam Nut 3/4" Bore 16 TPI Left-Hand Thread Zinc-Coated

The Rock Krawler RK00009L is a 3/4" bore, 16 TPI left-hand thread jam nut designed for use with Rock Krawler suspension control arms, track bars, and adjustable links. This jam nut features a 1-1/8" head width for wrench engagement and is finished with a corrosion-resistant zinc coating to withstand harsh off-road and weather conditions.

Key Features:

• 3/4" bore diameter for proper fitment on Rock Krawler threaded suspension components
• 16 TPI (threads per inch) for secure, precise thread engagement
• Left-hand thread (LHT) — critical for correct installation on left-hand threaded adjustment sleeves
• 1-1/8" head width for use with a standard open-end or crowfoot wrench
• Zinc-coated finish for corrosion resistance in demanding environments
• Universal fitment — compatible across Rock Krawler suspension systems

Jam nuts are a critical safety component in any adjustable suspension system. They lock the joint or rod end in place after length adjustment, preventing unwanted movement that can lead to thread failure. Rock Krawler recommends applying red Loctite to the threads and torquing jam nuts to the specification appropriate for the bore size to ensure long-term reliability and safety.
