ACDelco Specialty Air Lift Shocks are designed to help provide better handling for temporary situations, such as when a vehicle hauls a heavy load or tows a trailer. They have an adjustable air pressure, between 25 and 200 psi, and up to 1,100 lbs (per pair) of load-carrying capacity*. Under loaded conditions, these shocks help maintain level vehicle height by adding or releasing air as needed, assisting in the stabilization of alignment angles, reducing other suspension component wear, improving handling, and reducing the risk of bottoming out. ACDelco Specialty Air Lift Shocks are ideal for temporary load hauling, including towing boats and trailers. *Not to exceed vehicle GVWR (Gross Vehicle Weight Rating). Product does not increase payload. ⚠
| FAQ - Answer 1 | Yes, though shocks and struts perform a similar function, they vary greatly in their design. Struts are an integral part of a vehicle's suspension system, providing structural support for the vehicle and, as such, are a safety subsystem. Shocks work separately from any structural function, simply absorbing and damping the bumps from the road. |
| FAQ - Answer 2 | Yes, all shocks and struts use hydraulic fluid (oil) to control damping. A gas charged shock or strut uses high-pressure nitrogen gas to reduce oil foaming during high-speed damping, and therefore maintains performance. |
| FAQ - Answer 3 | Yes, it is possible to do a quick check at home for wear on your vehicle's shocks or struts. You can look for any physical damage to the shock or strut housing or any leaking - this is especially common on rear units that tend to have stones kicked up by the front wheels. You can also perform a bounce test by taking each corner of the vehicle and pushing down hard. The corner should drop, rise and settle again. If the body continues to move up and down, there's a good chance your shocks need to be replaced. Though these home tests can indicate worn shocks or struts, it is also recommended that you take your vehicle to a qualified service technician and let them do a thorough inspection every 12 months or 12,000 miles. |
| FAQ - Answer 4 | Yes, if you are replacing your vehicle's struts. However, it is not necessary to get your vehicle aligned when replacing your vehicle's shocks unless there was or is a previous issue. |
| FAQ - Answer 5 | Yes, it is important to choose the correct shock or strut for your vehicle model and year, as well as for the location in the vehicle. |
| FAQ - Question 1 | Is there a difference between a shock and a strut? |
| FAQ - Question 2 | Do gas charged shocks or struts contain oil? |
| FAQ - Question 3 | Can I check my vehicle's shocks for wear? |
| FAQ - Question 4 | Should I have my vehicle aligned after replacing my shocks or struts? |
| FAQ - Question 5 | Do I need different shocks for front, rear, left, or right applications? |

| Good Maintenance Practices - Section 1 - Header | Your vehicle's shocks and struts slowly deteriorate over time, though this wear is normally difficult to detect. To maximize your vehicle's ride comfort and safety, it is recommended to replace your vehicle's shocks and struts every 50,000 miles. Worn shocks and struts can also cause additional wear to other vehicle components. Affected components include: |
| Good Maintenance Practices - Section 2 - Bullet 1 | Leaking oil or wetness along the body of the shock or strut. |
| Good Maintenance Practices - Section 2 - Bullet 2 | Broken mounts, worn or missing bushings. |
| Good Maintenance Practices - Section 2 - Bullet 3 | Broken, damaged, or missing mounting hardware. |
| Good Maintenance Practices - Section 2 - Bullet 4 | Severely dented reservoir tube, bent or scratched piston rod. |
| Good Maintenance Practices - Section 2 - Bullet 5 | Cupped tire wear. |
| Good Maintenance Practices - Section 2 - Bullet 6 | Damaged strut body springs, seats, and bushings. |
| Good Maintenance Practices - Section 2 - Bullet 7 | Defective strut bearing or missing plate. |
| Good Maintenance Practices - Section 2 - Header | To inspect your shocks and struts to gauge wear, check for: |
| Mounting Hardware Included | Yes |
| Programming Required | No |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 1 | There is excessive nose dive while braking |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 2 | Your vehicle has 'acceleration squat' |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 3 | Your vehicle does not return to a neutral position |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 4 | Your steering pulls |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 5 | There is a strut mount or bearing noise |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 1 | Your ride is harsh, bumpy or shaky |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 2 | Your vehicle bounces excessively |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 3 | Your vehicle veers in side winds |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 4 | Your vehicle leans or sways while turning |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 5 | Your vehicle bounces excessively after hitting a bump |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 6 | Your vehicle bottoms out |
| Signs of Wear & Troubleshooting - Section 2 - Header | It could be time to replace your shocks or struts if, when driving on a surface with bumps and/or dips: |
| Signs of Wear & Troubleshooting - Section 3 - Bullet 1 | If your vehicle's height seems lower than normal when measured |
| Signs of Wear & Troubleshooting - Section 3 - Bullet 2 | If you notice fluid leakage from your vehicle's shocks or struts |
| Signs of Wear & Troubleshooting - Section 3 - Bullet 3 | If your vehicle's shocks or struts have dented or heavily scratched housings or mounts |
| Signs of Wear & Troubleshooting - Section 3 - Header | Uneven patches of wear on the edges of your tire can be a sign of weak ride control (shocks or struts). This wear, called cupping, appears as scalloped dips around the surface of the tread. Other signs it could be time to replace your shocks or struts include: |
