If you are restoring an aging Jeep and want to match the factory original seat - or you simply enjoy the look of older models - then the TrailMax II Classic Low Back Vinyl Seat is what you have been searching for.

The TrailMax II Classic front bucket seat retains the fixed-position, classic styling of early-model, factory-original Jeep seats, yet offers the benefits of modern engineering to provide comfort and durability.

Atlas Frame - Seat frame is electrostatically painted to resist corrosion and hand welded for added strength, ensuring that your seat maintains its shape.

Variable Rate of Resistance Springs - Seat springs respond to increasing pressure with increasing support, making trips down the road - and the trail - a smooth experience.

Ultimate Foam - The closed-cell, high-density seat foam provides a firm, comfortable ride. The foam is designed to maintain the original shape of the seat for years and treated with waterproof "skin" to prevent waterlogging.

Seat Cover - TrailMax II seat coverings are constructed from premium vinyl fabric that maintains its shape in any temperature. The fabric is designed to resist damage from the elements - mildew and UV rays - and regular wear and tear, such as abrasions.

The TrailMax II Classic Low Back is manufactured to bolt to the vehicle's original seat riser, but requires the Bestop Seat Adapter Bracket (B51256) for installation of models 1997-2002 and the Bestop Seat Slider with Adapter for models 2003-2006 (Driver Side - B5124501/Passenger Side - B5124801). The seat is backed by a 1-year limited warranty and comes in vinyl factory-match Black color.

  • Fit & Compatibility of Bestop Low Back Bucket Seat B3942937 on 1977 Jeep CJ-7
    On a 1977 Jeep CJ-7 that has the original seat riser the Bestop Low Back Bucket Seats # B3942937 (spice color) and # B3942901 (black) are direct fits. Only for certain later models years, 1997 through 2006, are adapters required to install these non-reclining bucket seats. We do not happen to have these two items in stock for me to measure their mounting hole spacing so I called Bestop.
