Air Lift Accessories and Parts - AL52440

Air Lift's Lock-N-Lift spacer kit lets you add air springs to your lifted vehicle. These spacers go between the air springs and the mounting brackets, filling the gap between the air springs and your lifted suspension.


Features:

  • Allows you to install air springs (sold separately) on your lifted vehicle
    • Closes the gap between the helper springs and your lifted suspension system
  • Designed for vehicles with a 4" lift
  • Works with Air Lift's LoadLifter 5000 and LoadLifter 7500 XL, as well as other brands such as Firestone
  • Made of Zytel nylon, a durable, corrosion-proof material that is lighter and stronger than steel
  • Installs easily with a modular snap-and-lock design
    • Fits between air springs and mounting brackets
  • Made in USA
  • 2-Year limited warranty


When you lift your vehicle, you create a gap between your frame and your factory suspension. Because of this, your air springs won't make appropriate contact with your suspension system and you won't get the support you're looking for. If you want both a lifted vehicle and the added support of air springs, then you have to close this gap. With Air Lift's Lock-N-Lift spacer kit, you can effectively do that, ensuring that your lifted vehicle will ride safer, handle better, and navigate rugged roads with ease. Lock-N-Lift is installed between the air bags and the mounting brackets, closing the gap between your frame and your OEM suspension and solving your problem.


With its modular snap-and-lock design, Lock-N-Lift installs easily. The spacers work with Air Lift's LoadLifter 5000 and LoadLifter 7500 XL, as well as other brands such as Firestone. And they are made of corrosion-proof Zytel nylon, a material that is both stronger and lighter than steel.

Review from a similar Air Lift Lock-N-Lift in Accessories and Parts


After blowing three fittings out of the top of the air bag, and calling Air-Lift, I found out that I needed the spacer kit, sold separately. My truck has the camper package and the additional spring increases the distance between the mounting plates in excess of the design. I missed that memo. Air-Lift was very professional and responsive sending new bags and fittings within days. That is as American Strong as it gets. With the lift plates, "Lock-in-Lift Spacers AL52130" installed, product works great. To etrailer: Include the memo/diagram of the necessary distance between the mounting plates. 410076

  • Are Spacers Needed to Install Air Lift LoadLifter on 2016 Ford F-250 with 4 Inch Lift
  • If the lift on your 2016 Ford F-250 is a suspension lift you almost definitely are going to need spacers. If it's a body lift you won't. With that being said a 4 inch suspension lift doesn't always mean you need a 4 inch spacer. You need to measure the space between the mounting points of the brackets and subtract the height of the air spring you're going to be install. The difference is the size spacer you need. If you're installing the Air Lift LoadLifter 5000, part # AL88396,...

  • Will Air Lift LoadLifter 7500 XL Air Helper Springs Fit 2008 Dodge Ram 3500 with Lift Kit
  • The Air Lift LoadLifter 7500 XL Air Helper Springs # AL57595 will fit about a 1" block lift on their own. If you have a lift higher than that for your 2008 Dodge Ram 3500 then you need to add some spacers to accommodate your lift. Spacers are offered in a 2" # AL52420 and 4" # AL52440 option depending on how much of a lift you have. These can support up to 7,500 lbs so if you are towing a 14,000 lb trailer you will have support for the first 7,500 lbs. Please note that suspension enhancement...

  • Air Bag Helper Springs for a 2014 Chevy Silverado 1500 with 6 Inch Lift
  • Does your 2014 Chevy Silverado 1500 have a 6 inch lift or is it the 6 foot bed? I ask because Air Lift kit # AL89204 only fits short bed models so if your truck has the 8 foot bed you would need to look at other options. Lift kits are interesting because you could have a 6 inch lift kit but the actual increase in height between the frame and axle might be less than 6 inches. This is important when picking out kits and available spacers. Air Lift's tallest spacer is 4 inches, # AL52440....

  • Suspension Enhancement Options For 2001 Ford F-250 4x4 With 4 Inch Lift Kit
  • You have many options for a 4 inch lift on your 2001 Ford F-250 4x4 regarding suspension enhancement to reduce sag. For an air spring option, I recommend the Air Lift LoadLifter 5000 Air Helper Springs - Rear Axle # AL57390 along with the Air Lift Lock-N-Lift Spacers for Lifted Vehicles - 4" Lift # AL52440. Another great option is the Firestone Ride-Rite Air Helper Springs - Double Convoluted - Rear Axle # F2550 along with the Lift Spacers for Firestone Ride-Rite Air Helper Springs...

  • Recommended Suspension Enhancement System for 2013 Toyota Tundra With 6-Inch Lift
  • The Air lift LoadLifter 5000, part # AL88299 is designed to fit your Tundra if you do not have a fifth wheel or gooseneck hitch in the bed of your truck. If the truck has a suspension lift you need to measure the space where the airbags are going to sit to determine the size of spacer you need. For Air Lift we carry two, part # AL52440 for a 4 inch spacer and part # AL52420 for a 2 inch. To be able to control the amount of air you keep in your suspension system I recommend the Air...

  • Recommendation for Adding Spacers to AirLift 1000 Air Helper Springs on a 2005 Jeep TJ
  • I recommend adding Air Lift Lock-N-Lift # AL52440 spacer kit to the AirLift 1000 Air Helper Springs for Coil Springs # AL60811 as it lets you add air springs to your lifted vehicle. It will work with vehicles with up to a 4 inch lift. The diameter of the spring 5-3/8 inches and 4 1/2 inches tall. I added an instruction link for you as well.

  • Air Lift LoadLifter 7500 XL Air Helper Springs for 2016 Ford F-250 with 4 inch Lift
  • As long as the 2016 Ford F-250 Super Duty has 4wd, you can use the Airlift air springs part # AL57596 with a 4 inch lift and a 5th wheel hitch in the bed. You need spacers to make up the room from the 4 inch lift in your suspension. Just because you have a 4 inch lift does not always mean you need a 4 inch spacer. You have to do a couple measurements to figure out which size spacer you need. You need to measure from the frame to the top of the axle on the Ford. Then subtract the operating...

  • Air Bag Helper Springs for a 2015 Ram 1500 with 4 Inch Rear Lift
  • There are no spacers for the AirLift 1000 air springs # AL60818 for your 2014 Ram 1500. You could still use the springs (assuming that the rear coil springs in your truck are stock) but the truck will squat A LOT before they engage. Depending on how much the stock suspension travels the truck could bottom out before the springs can even engage. What you could do instead is use air bag kit # AL57370 and then add spacer set # AL52440 for vehicles with a 4 inch lift. In this case the 4...

  • Recommended Air Lift Suspension Enhancement for 2015 Silverado 1500 with 4-1/2 Inch Lift
  • For your 2015 Chevrolet Silverado 1500, I recommend the Air Lift LoadLifter 5000 Air Helper Springs # AL57204 if you do not have an 8 foot bed. For an 8 foot bed, you will instead use # AL57211. These will provide your Silverado with up to 5,000 pounds of load-leveling support and help to reduce strain on its rear suspension. You can manually adjust the air pressure in order to get an even load distribution. Each spring can be inflated independently for side-to-side leveling of off-center...

  • Air Lift Spacer Kit Recommendation for Use with Air Lift LoadLifter Kit # AL88289
  • Air Lift makes spacer kits that are designed for 2 inch and 4 inch lifts. For that you'd want the part # AL52440 for a 4 inch lift or part # AL52420 for a 2 inch lift. Either kit works well with the Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88289.

  • Air Lift Suspension Enhancement for 2016 Ram 1500 with 6 inch Lift
  • You can install suspension enhancement on your 2016 Ram 1500 that has a 6 inch lift like the Air Lift LoadLifter 5000 Air Helper Springs # AL57365 (this is correct kit for your truck) but you do need the correct size spacer like you mentioned. The correct size spacer will actually be a 4 inch spacer like part # AL52440 since 6 inch lifts typically only add 4 inches to the height of the suspension. I attached an install video for the air bag kit on a 2016 Ram just like yours as well.

  • Jounce Bumper Spring versus Air Springs on a lifted 2008 Ford F-250
  • For your 2008 Ford F-250, I can help you with enhancing your factory suspension. You are correct in saying that the air bags have more flexibility, but do require more maintenance than the jounce spring systems which are maintenance free. Either option will work with your lifted truck, but if you are primarily concerned about suspension support when towing your 5th wheel, then the jounce replacement springs are an excellent low cost option. For your needs, I'd suggest the Timbren Rear...

  • The Air Lift LoadLifter 5000 Air Helper Springs - Rear Axle # AL57391 are a confirmed fit for your 2017 Ford F-250 truck. Due to the 4 inch lift, you will also want to add the Air Lift Lock-N-Lift Spacers for Lifted Vehicles - 4" Lift # AL52440. This combination will give you the air springs compatible with your lift and will give you the manual inflation option. If you want to add the ability to adjust your air springs at any time, I recommend adding the gauge and compressor. The...

  • Are Spacers Needed to Install Air Lift LoadLifter Air Springs on 2012 Ram 1500 with 5 Inch Lift
  • The Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88370 that you referenced are confirmed to fit your 2012 Ram 1500 but whether or not you need to add some spacers will depend on what exact kind of 5 inch lift you have. If the lift on your Ram only lifts up the body of the truck away from the frame then additional spacers aren't needed. If it is a suspension lift though you will just need to add the Air Lift 4" Spacers # AL52440 to close the gap between the springs and suspension....

For your air springs, I recommend the Air Lift LoadLifter 5000 Air Helper Springs - Rear Axle # AL57370. For your 4 inch lift, you will also need the Air Lift Lock-N-Lift Spacers for Lifted Vehicles - 4" Lift # AL52440 for this installation. I've attached a video to show you this install. This combination will give you the air springs you are seeking with manual...

  • Can Air Lift Suspension Enhancement Kit Fit 2004 Dodge Ram with 6 inch Lift
  • Air Lift does make spacer kits that allow their suspension enhancement kits like the part # AL52204 to fit on trucks with lift kits. For example they have the part # AL52440 which is a 4 inch spacer. Oddly enough 6 inch lifts commonly only add right at 4 inches of suspension travel so a 4 inch spacer like this would be what you'd need. You'd need to determine how much of your lift is a suspension lift to determine if this is the correct spacer kit you'd need. You could contact the manufacturer...

  • How Many Spacers Do I Need for the Air Lift LoadLifter 5000 Air Helper Springs on a Lifted F-250
  • In order to determine if you need to add additional lift spacers to the Air Lift LoadLifter 5000 Air Helper Springs on your Ford F-250 you will need to measure the distance between the upper and lower airbag brackets, then subtract the height of the airbag. For example, if the distance between the upper and lower airbag brackets is 10" and you have the 5813 airbag which is 6" tall, then you would need to add a 4" spacer part # AL52440 . I have attached a photo for you that shows where to...

  • What Size Air Bag Spacer Do I Need for a 2012 Ford F-150
  • It can be rather difficult to give an exact answer on the correct lift spacer for air bags to use with a lifted truck as not all lift kits are the same. Therefore, measuring is needed to determine the correct size or you could always buy both and return the one you don't need. The reason for this is that although the manufacturer of the lift kit may state it is a 6" lift, most of the time it does not indeed lift the truck that much. Also, there is a factory rake so the kit could also lift/level...

  • The air bags for that work with your 2012 Ram 1500 are the Air Lift LoadLifter 5000 Air Helper Springs # AL57365, though you will need to measure to ensure that you have the right amount of space to use air bags. To do this, measure from your jounce bumper strike plate to the vehicle frame; that measurement should be 8-1/8" in order for air bags to fit your truck. If you take a look at the accompanying photo you can see exactly where you need to measure. In regards to your 4-1/2" lift,...

  • To determine the correct spacers in for your GMC Sierra with a 4-1/2" lift and Air Lift 5000 Air Helper Springs such as # AL57338 you wll need to do a bit of measuring. There is a diagram I added from Air Lift what you will need to measure to ensure the correct spacer kit. You will need to measure the total distance between the mounting surfaces, and subtract that by 5-1/2", which is "A", the air spring design height for these air bags. That will give you the correct lift spacer, which...

  • Spacers Needed for Air Lift LoadLifter 5000 on Lifted 2006 GMC Sierra HD 2500
  • In order to use the Air Lift LoadLifter 5000 # AL57275 with a lifted truck, you will need to use spacers that match the amount of height gained in the rear after installing your lift. For example, if your rear end raised 4" after the lift, you would need 4" spacers like the # AL52440 . You'll want to use the 2" spacers # AL52420 for 2" of lift. If you have a different amount of gain from the lift on your 2006 GMC Sierra 2500HD let me know and I can recommend a different spacer.
