2015 Jeep JK 2-Door Bestop Sunrider Leaking at Passenger Door — Expert Fix

Quick answer: A 2015 Jeep JK 2-Door Bestop Sunrider leaking at the Passenger Door in Heavy Rain is almost never a bad door seal - it is the missing body-side weatherstripping Jeep left off the body, so the door seal has nothing to compress against. The permanent fix is adding body-side weatherstripping for the JK; most owners install it themselves in under an hour with no special tools.

Hi Angel,

Thanks for reaching out.

Based on what you described, your 2015 JK 2-dr is exhibiting one of the
most common leak patterns we see. The fact that the leak started after
installing the Bestop Sunrider can make it seem like the top is the cause,
but in many cases the Sunrider simply changes how water is directed around
the door opening, exposing an existing weakness in the factory door sealing
system.

The water you're seeing along the side of the floor mat and seat is
consistent with water entering around the upper passenger door opening and
then traveling behind the weatherstripping before running down into the
cabin.

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 door openings, 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 weatherstripping or
changing roof configurations.

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
that allow water intrusion and also helps make the cabin noticeably quieter
by sealing out outdoor wind and road noise.

Below is a link to the leak fix kit that will solve your issues.

(Select soft top.) If/when you put your freedom panels back on, there's
extra material included with the kit for that installation too.

If you have any additional questions, feel free to reply to this email or
contact me directly. I'm happy to help.

Best regards,

Tony
