    As a jeeper, there's nothing better than a day of 4-wheeling through mud and rough terrain. The muddier and bumpier the terrain, the better! You've outfitted your rig to fit the way you ride, from protection to performance. With the rough rides you take on, a loose cap on your oil filler can mean disaster.

    The Devil Is In the Details
    Oil filler caps are probably not something you think about often. But if a filler cap comes off, off-roading can sling oil all over your engine. The worst-case scenario is that you lose so much oil it blows your engine. It's a detail you just can't afford to miss. So check the tightness of yours regularly, knowing that we've got replacements for you from brands like Rugged Ridge and Omix-ADA.

    Sized and Priced Right
    When your order a filler cap from us, you'll specify your make and model because they're designed to fit. Need a Jeep 4.0 oil cap? We've got you covered. That's an engine you want to take good care of! And with our affordable pricing backed by a 90-day price match guarantee, you know you're getting the best value. Place an order today so you have a back-up cap ready!

    A History of Serving Jeepers Like You
    At 4WD.com, our mission is to bring the selection and prices jeepers need together in one easy to use place. The reason is simply that we are jeepers, too. We were established in 1977 by avid jeeper Tom Kennedy who wanted to make it easier to find high quality Jeep parts. Since 2006 we have been owned by Transamerican Auto Parts Company, LLC, which George Adler established much the same way over 50 years ago in a small garage. This means that from a Jeep oil cap to tires and transmission parts, you can trust us to be your one and only stop for aftermarket parts.
