This heavy duty outer tie rod end is a high quality replacement package for all V8 power steering, 1965-66 Mustangs. We use larger Moog 1/2” outer tie rod ends instead of the stock 3/8” units. This tie rod end must be used with our heavy duty large spindle kit. This larger tie rod offers much more strength and reliability in a very stressful area. Uses ES638S sleeve left hand only.
