For the added convenience of being able to air-up or air-down your tires to accommodate various types of terrain, a Smittybilt Air Compressor is the most powerful compression unit in its class with a 1/3 horsepower oil-less direct drive motor and a 30 amp inline fuse.

Climbing over rocks, tearing down a rugged slope, blazing a trail through mud and undergrowth—all of these are bound to challenge your tires and eventually lead to one slipping off the rim or blowing out. 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. Take the shot—order today!

5.0 Good compressor

So far so good. Gets the job done and it's nice to bring for off roading.

4.0 Smittybilt 5.65 CFM Air Compressor

My husband loves it, but agrees with other reviewers that the yellow hose is to flimsy and he's replacing some of the connectors with stronger parts. He's super happy with it though. I think guys are happier when they customize their stuff anyway.

1.0 Don't waste your money

I bought this brand new 2 months ago and it quit pumping air motor runs and it doesn't pump. I only use this pump for some air bags for my truck

5.0 Great product and price

Works fantastic. Filled up all 4 tires in no time at all after a day in the dunes.

5.0 Does the job as advertized.

Took this guy out to the Swell with a few rigs. Went from 15psi to 35 in about 2-3 min per tire on my 35x12.5x15s Used it on 3 vehicles, taking a break between each vehicle per the duty cycle. It gets HOT, need to let it cool. But it cools quickly. The inline gauge is a little off compared to my milton gauges, but I just noted where 35psi actually was on the gauge, and it's smooth as silk. Planning on using it to pressurize an ABS pipe solar shower. Great buy.

5.0 If you want a quick air up grab this bad boy

Awesome pump. After a couple of differnet compressors I am happy to say this one has ended the search

5.0 Worth every cent!!!

This air compressor looks like a sowing machine. The motor is absolutely overbuilt and huge which gives it great efficiency. The compressor is very fast for being portable. Hoses feel like good materials. I use it on 35" tires which it has no problem, takes a minute or two to double the PSI. Only downside is you have to shut it off for the PSI gauge to read accurate.
