Hi Larry,
Thanks for reaching out, and thank you for the kind words about our kit.
The leaking you’re experiencing at the passenger door on your 2012 JK
4-door hardtop during heavy rain is a very common issue on these vehicles.
The root cause comes down to the factory sealing design. Unlike most
vehicles on the road today, the Wrangler JK does not have a proper
body-side sealing surface. Instead, the door seals are trying to compress
directly against painted metal. Since painted metal is not a consistent
sealing surface, small gaps can develop around the upper passenger door and
A-pillar area, allowing water to enter during heavy rain, washing, or while
driving.
Even though the factory seals may appear to be in good condition, the issue
is usually not the seals themselves—it’s the lack of a proper gasketed
sealing surface for them to compress against. That’s why many JK owners
continue experiencing leaks even after replacing or adjusting
weatherstripping.
Our leak fix kit was specifically designed to address this problem by
creating the missing body-side sealing surface that the factory design
lacks. This allows the door seals to compress evenly and consistently,
eliminating the gaps that allow water intrusion.
Below is a link to the leak fix kit that will solve your issues.
If you have any additional questions, feel free to reply to this email or
contact me directly.
Best regards,
Tony
