Installation Notes and Tips

Verify the spindle thread size before installation; this kit uses M20-1.25 threads. Because the hardware is one-time-use, replace it during service rather than reusing removed components. Confirm front-position fitment against the vehicle listing, especially on Chevrolet Express, GMC Savana, Chevrolet C/K, and GMC C/K models.
