Low air pressure is the main cause of air spring failure, and this system prevents that before it happens. The Air Lift Load Controller II senses when pressure drops below your set minimum—typically 5 psi, adjustable up to 10 psi—and restores it automatically. That means your helper springs always stay above the safe zone, giving you longer spring life and consistent support whether you’re hauling or just cruising unloaded.
For light to medium-duty use and occasional towing, the single-path setup makes things straightforward. A single in-cab analog gauge lets you monitor and adjust one pair of springs together. Both airbags share the same pressure, so your ride stays level front-to-back without worrying about uneven side-to-side adjustments. When your load changes, a quick tap on the switch brings everything back to balance.
Some compressors rattle or buzz when they kick on—this one doesn’t. The Load Controller II runs with high-volume airflow that’s nearly vibration-free, so you just see the gauge move without hearing much noise. You get smooth, reliable inflation every time without the constant hum in the background.
No hunting for extra parts to get started. The kit includes the wiring harness and fittings needed for a straightforward install. Once mounted, the compressor’s automatic sensor and single-path controller take care of the rest—keeping your air springs right where they should be without constant manual checks.
With a compressor duty cycle of 4 minutes on and 5 minutes off, it’s made for typical towing and hauling routines. The Load Controller II works with any brand of air springs, so you can count on it to deliver stable pressure maintenance across different setups. It’s a light-duty system that handles the work quietly, keeps your suspension healthy, and makes day-to-day adjustments simple.

Works great. I haul 2 snowmobiles on a deck on a 1/2 ton Silverado and it adds stability to the truck. I have a slow leak when the temps drop, otherwise it would get 5 stars.
Bags are great but the compressor didn’t even last a year
system working perfectly after one year. Pump a little loud but ride height is perfect, No failures and I use my truck everyday. great value and simple to install.
. Box came looking like it was ran through a mine fiend though. Everything inside looks in ok but will find out when I install it this weekend. But definitely will buy again from etrailer nothing but great reviews for them. usps who had package transferred to not so much. Know it wasn't ups cause never had one look like this from them
Everything I needed. Installing now.
Excellent service and sales representative.
Compressor holds great pressure.
Fills up airbags quickly
Web site is very easy to follow and the product is top notch as well as how quickly it was sent
Most impressive was the awesome customer service I received from Kaylyn! She took the time to answer my questions and process the order quickly so I could get the air bags and compressor in time to install before my 2,500 mile road trip next week.
KYB shocks and struts for my 05 Pilot EX, along with the air ride load leveler pillows were here within a week of ordering at a great price! Happy with front end of my purchase, now for the install! Kudos to etrailer.com!
The air suspension bolted into place with no issues ... perfect fit. The hardware for the air pump and gauge was complete. Had the job done in a day.
The install was very straight forward and the instructions were great. I had more than enough air line for an extended cab short box chevy. I would buy this again in a heartbeat. It has no problems supplying enough air to the air bags and it does it quickly and quietly.
I will say excellent but truthfully I just installed today. Will know more after a trip or two. Works as it should. Had plenty of everything I needed. Only thing I did not like was lack of a relay. I personally don't like pulling 15 amps off of my fuse panel. I used the supplied wire as a signal for a 30 amp relay and pulled it from a lug near the battery. Maybe not necessary but made me feel better. The compressor is noisy. Would have installed under a seat bit did not like the noise. Found a place that should keep it out of water splashing from tires. We'll see. Only problem was the pressure switch was supposed to be set at five pounds. More like one. Easy to fix.
Worked for what I needed easy installation even made my 1993 Ford f 350 4x4 ride smoother thanks for the fast shipping
Good unit runs well, but the airline and fittings in the kit leave a little to be desired. I’ve had to replace lines twice within a year now. But aside from that it’s a solid little unit.
Installation of the Airlift air helper springs and air compressor was easy ,had 1200 lbs. in the bed of my truck and could"nt be more pleased with the load leveling and the ride , can"t wait to hook up my 5th wheel to see how it rides,very good product highly recommended .
I've had this for about a year so far, I mounted it underneath the passenger rear door (outside) of my Dodge 3500 to run the air bags. I haven't had any problems at all. Great Product. FYI found out later the have a wireless one.. would have spent a lot less time installing. oh well
Everything works great!! Takes a little time to install if you want to do it right. But made the ride much better when pulling my 39’ Toyhauler.
Purchased Air Lift compressor system and air bags for my 2014 Town and Country to pull a 19' TT to Florida from Indiana. After installing, found out compressor would not hold pressure. Contacted Air Lift and they shipped me a new one. Have not had any more issues with system. I integrated the controls into my lower dash panel and it looks great. Have pulled to Michigan, Nashville, TN. and to mid Florida with no problems. Would recommend this product to anyone.
I first realized that I needed some help leveling my 2006 Yukon XL right after I hooked my 2 place trailer to the vechile. My previous Yukon had self leveling rear shocks, the 2006 did not come w/ that option. I mounted the compressor on the top of the passenger side wheel well, (there is plenty of room there, & away from engine heat) I mounted the pump & dump switchs , & the pressure gage on a piece of kydex that I cut to fit in the little cubby that is below the heat/ac controls. The hardest part was getting the lift "bags" into the coil spring tower, time & patience. The install looks factory, & works great to level the vechile while towing. Great product!
It's a quality kit and it works great. Install was a little tough on 2017 Ram 1500, otherwise I would rate it 5 stars. It's soo much better than having to manually inflate my air springs. Would buy again in a heartbeat.
This product is working great! The install instructions are quite vague & I needed to watch a couple videos for details. Looking back I think the extra $$ for wireless would be the way to go.
Some of the best installation instructions I’ve ever used for after market accessories, took about four hours, most of which was finding a path through the trucks firewall and a switched fuse to plug in to. Works great.
It took a bit of strategizing, but installing on a Chrysler Town & Country was a perfect fit. The entire installation was in the interior, with the airline exiting the compressor to the rear bumper through the rear left panel louvered baffle. The initial functional test was satisfactory except the pressure gauge was inoperative. A replacement gauge was promptly shipped. Unfortunately, the replacement gauge was not properly calibrated, but was still serviceable by creating colored decals to depict the air helper springs operating pressure range.

After a year, not a single complaint. No worries of the pressure ping too low for typical driving, as it automatically adjusts to the minimum. On longer hauls with a lot of trailer tongue weight, manual adjusting is a breeze with the press and hold rocker switch.

Incredible customer service. Fastest I've ever went from "this is what I'm looking for" to ordered and shipped. Nothing but value added services. Thanks!
Nick, Thank you, it arrived on time. The Air Lift won't be installed till the 1oth. Looking forward it's performance when towing. Thank you again for the customer service. Have a Blessed Day! Randy
