How to Install a Bestop Black Vinyl Supertop NX on your 1988-1995 Jeep Wrangler YJ

Improper windshield adjustment will result in poor fitting top and doors, causing looseness or undue strain on the top.

After adjusting the windshield angle, make sure that the bolts on top of the sport tube and the windshield have been tightened.

Before installing the top, check the windshield measurement. The distance from the top lip of the windshield to the top outer edge of the body must be 75 1/8" on both sides of the vehicle. Measure 4"-6" inside the doors.

If necessary, loosen the #50 Tamper Proof Torx Bolt on top of the side sport bar. Adjust the windshield and tighten the Torx Bolt.

A loose Windshield Retainer may allow the top to disengage from the windshield, causing damage to the top and possible injury to the occupants of the vehicle. Make certain that the Windshield Retainer is securely fastened to the windshield during installation and at all other times by checking the tightness of the mounting screws every three months. Do not use any drill size other than 1/8". Failure to use the correct size may cause the Windshield Retainer to loosen.

Position the two piece Windshield Retainer on top of windshield frame. Use retainer pieces as templates to mark, center punch and drill eleven 1/8" holes. Install with eleven #8 x 1/2" Pan Head Screws.

Install the Left and Right Windshield Flanges on each side of the windshield frame. Mark, center punch and drill four 1/8" diameter holes. Install the door seals with four #8 x 1/2" Phillips Head Screws.

Install the Left and Right Side Belt Rails on each side of the vehicle. Use the existing holes, four 5/16" Phillips Head Bolts and four Tapping Plates on each side.

When drilling in the top edge of the vehicle body, check underneath for wiring for the rear lights. Pull the wiring out of the way before drilling.

Install the Left and Right Rear Corner Belt Rails on each side of the vehicle. Notice that the Corner Belt Rails do not butt-up against the Side Belt Rails installed in Step 3, this is normal. Use the Corner Belt Rails as templates to mark, center punch and drill two 3/8" holes in the top edge of the vehicle body. Some vehicles may already have some of these holes. Install the Corner Belt Rails with two 5/16" Phillips Head Bolts, two 5/16" Washers and two 5/16" Tapping Plates. At the location of the remaining hole in the Corner Belt Rail, next to the tailgate, mark, center punch and drill a 1/8" hole. Install a #8 x 1/2" Pan Head Screw.

Assemble the two halves of the Support Bow. Orient the two pieces to each other and lay them on the fl oor. Slide the pieces together, pushing down on the buttons. Once the two halves are together install a Snap Head Screw in the hole formed in the center, front of each bow.

Slide the ends of the front and rear bows into the tracks in the Side Belt Rails on each side of the vehicle. Start from the rear of the vehicle and slide the bow assembly toward the front.

Attach the drip rail at the front of the Bow Assembly to the pin on the Windshield Flange and lock it into place om both sides of the vehicle

Locate the top and orient it on the vehicle. Start with the outside snaps and snap it to the Bows.

Insert front of Top into Windshield Retainer.

Push Front Support Bow all the way forward.

Insert rear corners of Top into Rear Corner Retainers.

Pull the bottom of the Rear Support Bow back until it snaps into the notch in the Side Belt Rail.

NOTE: Zippers must not be caught or folded behind Rear Support Bow.

While pushing the lock buttons, push the spreader bars up until they snap into place. Do not push past horizontal.

Start the zippers 2-3 inches on the top and rear of the Quarter Windows.

Slip the plastic strip on the front of the Quarter Window into the retainer channel on the Front Support Bow.

Slip the plastic strip on the bottom of the Quarter Windows into the Side Retainers. Close the top and rear zippers on the Quarter Windows. 

Open the tailgate. Slide the Tailgate Retainer onto the bottom of the Rear Window. Close the Rear Window zippers. Push the Tailgate Retainer into the top of the Corner Belt Rails. Slip the plastic on the bottom of the fabric under the bottom of the Corner Belt Rails.

Fasten snaps on top, above doors, to studs on vehicle. Studs will slide to match location of snaps on top

Your Bestop product is made of the finest materials available. To keep it looking new and for the maximum possible wear, it will need periodic cleaning and maintenance.

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 or use Bestop-recommended Bestop Cleaner and Bestop Protectant. Bestop Cleaner and Bestop Protectant are specially formulated to provide a total cleaning and protection system. Bestop Cleaner will not harm vehicle fi nish, is biodegradable and environmentally friendly. Bestop Protectant protects against UV-fading, cracking and hardening.

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 or use Bestop-recommended Bestop Vinyl Window Cleaner, which safely cleans and protects vinyl windows while helping 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 the zipper cleaned and lubricated with a silicone lubricant will help prevent damage and keep the zippers in a 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. Squeeze lightly at fi rst and test the zipper. If the zipper continues to remain open squeeze more fi rmly with the pliers and try the zipper again. 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.
