These boots are sold as a set of four (4) boots.

A distinctive feature of these boots is the "shock absorbing" edge. You will notice the bulge on the boots. When using HPI drive cups, they are designed to act as shock absorbers that will displace the energy of rocks and debris rather than create an immediate pinch that causes the cuts in the currently available boots.

For ease of installation, if you are running aftermarket axles with removable pins, be sure to remove the pins for a much easier install.

Due to a wide variety of drive cups and axle combinations, please read the following information for tips on using our boots for your application.

Turtle/Phatdad drive cups: Trim off complete undercut at open end of boot. You will see this ring of material inside the large open end of the boot. The large reinforcing ring, seats into the boot and moves the boot inward requiring more material to be removed from the open end of the boot to prevent the boot from rubbing the bearing. The boot is now held in place by the ring, seating itself into the radiused bulge.
