Target Vehicle Fit

This roof-rail weatherstrip kit is designed for 1985-1988 Buick Regal models. It replaces the original seals that run along the roof side rails above the doors. Buyers restoring a Regal from this period will find the correct profile. Owners of other GM coupes or later Regal years cannot use this kit.

Installation Context

The kit includes the strips and hardware needed to fit into the existing roof-rail channels. No additional brackets or adhesives are required beyond what the factory design uses. Removing the old, brittle seals frees the channels for a clean install. Installers without access to interior trim tools may find the job slower.

Long-Term Sealing

The rubber compound resists compression set so the seal maintains contact with the door glass over repeated cycles. It continues to block wind noise and water intrusion after extended exposure to temperature swings. The material does not harden quickly under sustained UV and heat cycles.

Questions about this item

What is the first limit that shows up during sustained installation of the Fairchild KG3138 weatherstrip kit?

The kit includes installation tools sized at 12 x 12 x 6 inches, so workspace clearance becomes the limiting factor during prolonged fitting.

How much noise, heat or power does the Fairchild KG3138 kit generate when used all day?

The weatherstrip kit is a passive rubber and tool set with no moving parts, so it produces no noise, heat or power draw during continuous use.

What else must I already own for the Fairchild KG3138 kit to work on my 1985-1988 Buick Regal?

You need a 1985-1988 Buick Regal with intact roof rails matching OE part numbers 20737658 and 20737659, plus basic hand tools for removal and fitting.
