Important Notes

• Control arms typically add 1–2 degrees caster above stock alignment specifications.
• All aftermarket wheels should be test fit prior to mounting the tire to ensure proper clearance to the brake caliper. Some wheel profiles will not clear the brake caliper. These can be test fitted before the vehicle is lifted.
• For replacement ball joints use service kit ZONF8202. Ball joint is directional and must be installed with the 'dot' facing either inward or outward on the vehicle, otherwise damage may occur.
• This kit will NOT fit AT4X or ZR2 models with the Multimatic Shocks.
