• We recommend using 3” tall (8058-30) bump stop spacers for 35” tires and 4” tall
(8058-40) bump stop spacers for 37” tires

• You must run a minimum of 3” tall bumpstop spacers when using the PPM-8056 rear
track bar relocation bracket to prevent the track bar from contacting the exhaust at full
jounce travel.

1. The bumps stop spacers are angled to provide even contact when increasing the
pinion angle for using a CV style rear driveline. Position the bumpstop spacer on top
of the factory bumpstop pad so they lean forward.

2. Use the 3/8” x ¾” bolts to secure the bumpstop to the axle bracket. Use a flat washer under the head of the bolt and use the serrated flange nut by its self on the bottom. Torque the 3/8 bolts to 40 ft-lbs.
