2016 Jeep JK 4-Door Bestop Sunrider Leaking at Driver Door — Expert Fix

Hi Tony,

Thanks for reaching out.

The leaking you’re experiencing at the driver door on your 2016 JK 4-door
with the Bestop Sunrider 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 driver door and
A-pillar area, allowing water to enter during 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.

The Bestop Sunrider does not typically cause the leak itself, but like
other roof configurations, it can make existing sealing gaps around the
upper door opening more noticeable during rain and highway driving.

The most effective long-term solution is adding a factory-specific Jeep
leak fix kit with body-side weatherstripping. This creates the missing
sealing surface the factory design lacks, allowing the door seals to
compress evenly and consistently. Once installed, it eliminates the gaps
and resolves the water intrusion issue at its source.

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
