5/8-inch x 4-inch Non-Greaseable Shackle Bolt

5/8-inch x 4-inch Non-Greaseable Shackle Bolts are necessary to fasten the 60mm shackle springs to the centre rocker arms.

Non-greaseable shackle bolts also fit standard tandem springs.

Steel on steel parts requires grease to help reduce wear and tear.
