Installation Tips

Before you begin installing your new Trektop NX, please read all the instructions thoroughly, and watch the Bestop installation video. (See Support section on this page)

For a smooth fit:

For easier installation, the top should be installed at a temperature above 72º F. Below this temperature, the fabric may contract an inch or more, making it difficult to fit the vehicle.

It is normal for the fabric to contract and wrinkle when stored in the shipping carton. Within a few days after installation, the fabric will relax and the wrinkles will disappear.

Care and Maintenance of your Bestop Product

Fabric: The fabric should be washed often using soap, warm water and a soft bristle brush Rinse with clear water to remove all traces of soap. Bestop recommends using Bestop Cleaner (part no. 11201-00) and Bestop Protectant (part no. 11202-00) Bestop Cleaner and Bestop protectant are specially formulated to provide a total cleaning and protection system. Bestop Cleaner safely removes. Bestop Protectant protects against UV-fading, cracking and hardening, and repels dust, grease, dirt and mildew.

Windows: Keep windows clean to avoid scratching. DO NOT use a brush on the windows! Wash with a water-soaked cloth or sponge and a mild dishwashing detergent. Bestop recommends Bestop Vinyl Window Cleaner (part no. 11203-00), which safely cleans and protects vinyl windows and helps prevent UV damage. NEVER WIPE THE WINDOWS WHEN THEY ARE DRY. Be careful when cleaning snow or frost from the vinyl windows since they are easily scratched and may crack at low temperatures. DO NOT roll the sides or rear window in cold weather. The windows become stiff and
will crack. Cracks caused by misuse in cold temperatures are not covered under warranty.

Zippers: Keeping zippers cleaned and lubricated with Bestop’s Zipper Cleaner (part no. 11206-00) will help prevent damage and keep the zippers in smooth working condition. If a zipper opens behind the slider, the slider may have been spread apart. This problem can usually be repaired by using an ordinary pair of pliers to bring the sides back into parallel. Return slider to the end of the zipper in the normal Open position.

Repeat this procedure until the zipper operates correctly.

Water: Seeping through at the seams may be stopped by applying 3-M Scotchgard® on the inside of the seams. Rips in the fabric may be repaired with Bondex® iron on patches. Iron the patches to the Inside of the top, carefully following the Bondex® instructions.

Snaps: Keep snaps cleaned and lubricated with silicone to help prevent snaps from sticking to the studs. If a snap does become stuck to a stud, use a screwdriver and GENTLY pry apart to prevent permanent damage to the snap or the top fabric.
