2017 Jeep JK 2-Door Bestop Sunrider Leaking at Passenger Door — Expert Fix

Hi Lippolis,

Thanks for reaching out.

The leaking you’re experiencing at the passenger door on your 2017 JK
2-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 and top 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 areas, allowing water to enter during rain,
washing, or while driving.

With the Bestop Sunrider setup, those upper transition areas can become
even more sensitive to sealing inconsistencies, especially around the
windshield pillar and roof-to-door connection points.

Even if the seals appear to be in good condition, the issue is usually not
the seals themselves—it’s the lack of a proper gasketed surface for them to
compress against.

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 and top 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.
