Grease Fittings
Install the grease fitting on the TWIN TUBE SLEEVES. Make sure to pre-grease the sleeves to make sure the predrilled holes are free and the grease flows smoothly. If the ball joint is greaseable, grease it at this time. If it is maintenance free (no grease fitting), no action is necessary. Now install and align the arms to factory specifications.

On 2016–2018 steel knuckle only. There is a small burr on the upper ball joint taper. This can be removed with a file or a die grinder. Test fit the upper ball joint to make sure there is no interference.

The passenger side leaf spring bolts can be easily removed, so unbolt the leaf spring. Next, the leaf spring center bolts must be reversed.

Install the spring under the axle using only the front bolt for now.
On the driver side, unbolt the factory shackle. Leave the front bolt in place so you won't have to move the gas tank. Reverse the center bolt the same as on the passenger side.
