Jamar Performance 3-1/4" Hollow Spindle Right Hand Thread Spindle Nut With Lock Ring

3-1/8" - 12 thread. The 3.25" passenger side spindle snout nut is designed to complement the heavy duty design of the 3.25" snouts on your rear end and withstand the beating that both trophy trucks and short course trucks dish out. Instead of a clamp design, these nuts feature a locking washer that prevents the nut from tightening or loosing once installed. tt proam pro-am
