Cartridge kit includes the cartridge, a universal boot, boot retaining clip, zerk fitting for greasing, and a rod end retaining nylock nut. The boot included in this kit is an articulating style, generally for drag link use. For tie rod use, you'll want to use a JK-9703TRB boot. These cartridges are direct replacements for those found in our JK-9703TRL tie rod. This cartridge fits either end of that tie rod. See JK-9703W for a removal and installation wrench for these cartridges.
