All Balls Racing Tie Rod Upgrade Kits are a great replacement for those old worn out O.E.M. tie rods or ends. Tie Rod housings have been strengthened in critical areas. Tie Rod Upgrade Kits feature tie rods that are manufactured from seamless steel tubing and heavy duty rods. Upgrade failure-prone 10 mm tie rods ends to a heavy-duty 12 mm end. Order two kits to do the entire front end of the vehicle as you will need 4 tie rod ends. Note: Kit contents will vary by fitment and are subject to change. Kit Includes: 2 tie rod end(s). 1 miscellaneous part. 1 miscellaneous swing arm part.
