Transfer Case Drop KitInstallation instructionsIMPORTANT: Fits both front and rear for this modelOur Supreme Suspension transfer case drop kit is designed and tested to correct possible driveline angle changes that can occur when lifting your Jeep. Misaligned drivetrain components such as drive shafts can cause excessive vibration when traveling at highway speeds, and will also significantly speed up wear by applying extra strain to u-joints and CV joints. These transfer case drop spacers aid in correcting these issues by lowering the transfer case slightly from the factory location. Constructed from the same 6061 aluminum as our Pro-Billet line, these transfer case drop spacers will never compress, crack, or deform under the most rigorous conditions.NOTES: An alignment is always recommended after altering the height of your vehicle.
