Rubber hardness is increased noticeably over stock parts but is within the limits for Group N use. Manufactured with the same quality and on the same production line as the OEM bushings.
NOTE: Select your kit depending on the front control arms used. High caster front control rear bushings and both application front control arm front bushings are OEM parts.
Usually ships the next business day.
