The rotary recliner dial mount allows any user to find the perfect position, adjusting the seat back to a wide choice of settings with an ABS-composite knob that can be mounted on either the passenger's or driver's side.

close view of mesh pockets

The elastic mesh map pockets - conveniently mounted on the back of the seat - are durable and spacious, able to store much more than simply maps.

inside look at atlas frame

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 Sport is manufactured to attach over the vehicle's original seat riser, but requires the Bestop Seat Adapter Bracket (B51256) for installation of models 1997-2002 or the Bestop Seat Slider with Adapter (Driver Side - B5124501/Passenger Side - B5124801) for models 2003-2006. This seat comes in complementary, factory-match Black Denim and Slate colors.

Video Transcript for Review of Bestop Jeep Seats - Reclining Sport Front Seat - B3943815

Ellen: Hey everybody, I'm Ellen here at, and we're going to be taking a quick look at the Bestop TrailMax II Sport front seat. So this is a replacement for your Jeep front seat. You could use this for the driver or passenger side, and it gives you that nice bucket seat to replace a worn out or busted seat in your Jeep, or maybe just give you some new features that you didn't have before. Again, it is going to be a bucket style seat, so it's typically going to be more comfortable, has the vinyl fabric, which is water resistant, has a closed cell dense foam so you won't have to worry about any kind of water getting in there and causing any mildew. The fabric itself is also going to be mildew resistant and UV resistant, so this won't fade over time, it'll stay looking nice for many years to come, and it should be pretty easy to clean as well.Now this is the charcoal color. It does have a couple other colors available, it's also going to be available in spice, and black, and black denim, and it also is available in a fabric version.

So it'd be pretty much the entire same, except for this center section, which would be replaced with a fabric, again, in pretty much the same colors of spice, gray, or charcoal and black. You can find all of those here at, it's got relatively the same features. We'll be able to recline the seats with the dials on either side. It doesn't really matter which knob you use, it's just a rod going straight through. So you can see as I'm turning it on this side, it rotates on the other side as well.

So that allows you to recline the seat, adjust it up. It can also fold all the way down, so if you've got to get anything out of the back area, you can easily get in and out of there.And if we turn it around, it also has that back mesh pocket, so you can put any kind of smaller accessories in there, like a map, maybe some bungee cords or small tools, or anything that you might want to stash in that back seat. So it gives you a little bit more space as well, or a little more organization in your Jeep.Now this works for several years. It goes from 1976 up to 2006, so that covers the CJ-5, the CJ-7, and also the YJ and the TJ, including the Jeep Wrangler Unlimited from 2004 up to 2006. For a complete list of what this is going to fit you want to use our fit guide here, put in your year, make, and model and go from there, but pretty much from those years, you're good.

With those years, though, from about 1997 and up, you will need to have a bracket to work with this. They are sold separately, it just allows you to use the same tracks this has got, and you can find those all here at to figure out which one you need. They're all listed in the product page here at etrailer So you can figure out which ones you need for your particular Jeep.But you can use this for the driver or passenger side, it's pretty adaptable. It has progressive springs inside there so the more force that's put on them, the more support they give you. So even if you're going over bumps, it's still going to give you a nice, comfortable ride, has a sturdy metal frame underneath that as well to give you support, again, for many years, and should be a relatively simple install.

You'll just need a couple of wrenches and a little bit of time to get this guy in place.So should make a great addition to your Jeep, give you a nice, comfortable seat, and that's pretty much all there is to it for our look at the Bestop TrailMax II Sport seat. I hope this has been helpful in deciding if this is going to be the right replacement for you. Those other colors and fabrics are available here at if you want to check those out. Thanks for watching..
