The last thing you need is to be stranded while off-roading, so a good air compressor is a must-have for jeepers. When it's time to shop air compressors, 4 Wheel Parts is the place to go. Pick up a powerful Smittybilt compressor and stay prepared when you're off the beaten path.

The Value of an Air Compressor

Out in the wilderness, you know that help is far away if your rig gives out on you. Carrying or mounting the right equipment can be vital in helping you get back home. Portable air compressors, spare tires and tire patch kits are part of the essentials for off-road maintenance. Not only does having an air compressor on hand let you repair or replace tires when needed, it also lets you adjust tire pressure to best meet what lies ahead. With some types of terrain—for instance, sand, snow, mud or sharp rocks—partially deflating your tires is actually the right idea, improving traction and reducing the risk of punctures. A brand like Smittybilt will give you the highest CFM 12V air compressor you need, meaning adjustments and repairs are quick even for heavy-duty tires, putting you back on track sooner.

The Difference

When gearing up your Jeep for your next off-road expedition, you want the best quality equipment you can get for your money. Skimping out can put you and your rig at risk, but with 4 Wheel Parts, you don't have to compromise between price and power. Everything is listed at low prices, and we back that with a price match policy against any competitor for up to 90 days. This is your chance to get the Smittybilt air compressor you need.

5.0 Great Pump. Worth the $$

Great Jeep accessory. Takes about 2.5 min to go from 18# to 35# on a 35” BFG all terrain

5.0 Great Value

Bought when on sale. Contained everything I needed for airing up tires and was at a great cost. The guys in the Reno shop were great to deal with. Appreciate this staff

5.0 Works great

I have had this on my Jeep for 9 years using it offroad and street. It has pumped a lot of tires and has not failed me. I mounted this on my front bumper so that it is available quickly and I don't burn my hands putting it away! I am considering one for my RV as well.

5.0 One of the best and most affordable

With limited onboard options for a Gladiator, I opted for portable. This Smitty was an obvious choice, especially with a sale price. It fits well in my Decked Drawer. I replaced the battery clips with 50amp RV quick connects. It is easy to hook up and quickly inflates 35x12.5 tires.

4.0 Good

It works well! Only complaint is the carrying bag it came in looks like it won't last long. Already has a small hole in the inside.

5.0 Badass air compressor

Works like a charm!! Super durable and it fills tires fast. The gauge is also pretty accurate!

5.0 I love this Smittybilt Air Compressor

I love this compressor. I have owned and used it for over a year for my Jeep Wrangler and for a lot of other uses as well. I was able to get a Japanese Female Connector and used a brass close fit nipple to attach a Female US air chuck so I can attach any device I need. This compressor has helped us out a ton and I highly recommend it.

from Brigham City, UT |
This adapter makes it so you don't have to cut off the Japanese male end to use with American air chucks.  I bought this Japanese Female Chuck on Amazon


Question & Answers

Q: WILL THIS PUT 50+ LBS IN A TIRE? Answer this question

A: I only go up to 35-40psi.  Not sure about 50psi.  Probably would but it would take awhile.

Answered by FireDoc from NorCal on 08/24/2022

A: Yes and much more! Be sure to pay attention when filling the tire as it will keep on filing up.

Answered by GusB from Palmdale on 08/23/2022

Q: Does it shut off when it reaches pressure Answer this question

A: No

Answered by Scarlett from Cal on 01/27/2021

A: No not at any particular pressure. It would keep going, it will shut off if it gets to “hot”.

Answered by Kelly from 4WP Corporate Headquarters on 01/27/2021

Q: is this compressor weatherproof? can it be mounted in a truck bed or under the vehicle? Answer this question

A: This compressor may be hard mounted in a dry location. Be sure to use proper size wiring for your application. When using this unit with an air tank, you must install a back-flow preventing device to prevent damage to the cylinder head air valve.

Answered by Dave from 4WP HQ on 04/04/2022

Q: Does this Compressor need to be mounted upright, Or can it be mounted in any orientation?  Answer this question
