Installation & Application Notes

Clean mating surfaces before fitting cab seals to prevent air and water ingress. Use correct adhesive for glass bonding — structural automotive adhesive, not silicone. Check wiring harness routing when replacing doors or panels.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
