Installation Notes and Tips

Verify the compressed length, extended length, and end fittings before installation to confirm match-up with the existing support. Inspect the mounting points on the rear glass and body for wear or damage, and replace any worn attachment hardware if needed. Confirm the support is oriented correctly so the rod and tube connections seat fully at both ends.
