The 87365 Adjustable Camber Bolt allows additional camber changes up to ¦1.5¦ for a total of ¦2.5¦, on the popular Ford Crown Victoria, Mercury Marquis, and the Lincoln Town Car. Sagging of the suspension on these heavywieght vehicles is normal and routinely causes negative camber problems. Elongating the cam slots is completed in seconds using the new 85137 3/8" Rotary File for Aluminum.
