| Product Description | ACDelco Specialty Premium Monotube Shocks are designed to meet the demands of sport utility vehicles, 4x4s and light-duty trucks, which require greater control, handling, safety, and performance. These premium shocks feature consistent damping and rapid response characteristics, large chromed piston rods, high pressure nitrogen gas up to 275 psi, and a single tube design. Additionally, ACDelco Specialty Premium Monotube Shocks utilize floating piston technology that completely separates the oil from the nitrogen gas, producing extremely consistent operational control due to aeration elimination, and superior heat dissipation. ⚠<b> WARNING:</b> Cancer and Reproductive Harm - www.P65Warnings.ca.gov |

| 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: |
| Gas Charged | Yes |
| Boot Included | Yes |
| Dust Shield | Yes |
| 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 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 - 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 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. |
| 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 6 | Your vehicle bottoms out |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 2 | Your vehicle bounces excessively |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 5 | Your vehicle bounces excessively after hitting a bump |

| Signs of Wear & Troubleshooting - Section 2 - Bullet 4 | Your vehicle leans or sways while turning |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 3 | Your vehicle veers in side winds |
| 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: |
