These adjuster kits use a CNC machined stud which is notched to accept the matching tub and are designed for our urethane bushings.
5/8-18 studs come with standard bushing outer tubes (bushings will be 1-3/8" wide) and the threads are 1-5/8" long.
3/4-16 studs come with large bushing outer tubes (bushings will be 1-3/4" wide) and the threads are 2" long.
Parts included in one adjuster kit: threaded stud, tube, and jam nut.
Urethane bushings must be ordered separately.
Please see available options: 3/4-16 adjusters are only available straight, and 5/8-18 adjusters are available with RH and LH threads.
I clean the scale off the tube before welding – this will give a cleaner weld and help your tungsten to last longer.
