What Size Shocks for a 2 Inch Lift?
Confusion regarding the appropriate shock size for various lift heights is a common issue among vehicle owners. A 2-inch lift is quite popular, but it raises the question: What size shocks are needed for a 2-inch lift? Generally, the typical compressed and extended length of shocks for a 2-inch lift falls around 16 and 28 inches, respectively. However, these measurements can vary based on the specific make and model of the vehicle. Therefore, it’s crucial to determine the correct lengths accurately using proper measurement techniques.
This is just the beginning; there is much more to uncover regarding shocks for lifted vehicles. Continue reading to learn all the essential details.
Understanding Shock Absorber Lengths
The size of shocks for a 2-inch lift isn’t uniform across all vehicles, similar to how Torx bit sizes vary. The required shock absorber length can differ significantly depending on the vehicle, even if the lift height is the same. Consulting a shock absorber length chart can provide insight into the necessary shock dimensions, but you will first need to take specific measurements. Here’s a quick overview:
Static Length
The first measurement to take is the static length. You might be wondering: What is the static length for a 2-inch lift? This refers to the distance between the chassis mounting point and the suspension mounting point when the vehicle is at rest. It’s essential to take this measurement accurately while the vehicle is stationary. Generally, the static length for a 2-inch lift is approximately 25 to 28 inches. This measurement will be essential for calculating the compressed length later on.
Compressed Length
Next, you need to determine the compressed length for the shocks. This length is measured when the suspension is fully compressed into the chassis or body of the vehicle. Typically, the upper control arm will make contact with the bump stop in this situation. To measure this, first, determine the distance from the bump stop to the control arm. Then, subtract that value from the static length to obtain the compressed length for your vehicle’s shocks. For a 2-inch lift, this is typically around 16 inches, but ensure you measure your specific vehicle carefully.
Extended Length
The final measurement you require to select the correct shocks for your vehicle is the extended length. This measurement is also the distance between the chassis mounting point and the suspension mounting point; however, it’s taken when the vehicle is raised. When measuring the extended length, ensure the vehicle is lifted using a jack, such that the wheels are just barely touching the ground. This length will be greater than both the static and compressed lengths. For a 2-inch lift, the extended length is usually about 28 inches. These three measurements are essential for selecting the appropriate shocks for your vehicle.
How to Measure the Correct Shock Size?
As mentioned earlier, there are three crucial lengths you need to measure for the correct shock size. However, accuracy in these measurements is vital. Exact readings will help you select the best shock and correspondingly the appropriate spring rate for your vehicle. Here’s how to measure without errors:
Required Instruments
Before you start measuring, gather the necessary tools:
- Car Jack
- Jack Stand
- Ratchet
Procedures
Follow these steps carefully to minimize mistakes:
- Begin by measuring the static length. This is done by measuring the distance from the axle’s starting point to the mounting point on the frame.
- Next, measure the distance between the bump stop and the axle; this length will be used to calculate the compressed length.
- Now, jack the vehicle up off the ground and place a jack stand on the vehicle’s frame. Ensure the axle is hanging down fully.
- If an old shock is still installed, remove it so the axle can drop as far as possible. Use the ratchet for this step.
- Finally, measure the extended length by determining the distance between the axle mounting point and the starting point while the vehicle is lifted.
By following these steps meticulously, you will gather the necessary measurements for determining what size shocks are appropriate for a 3-inch lift as well. For added accuracy, you can refer to a shock length calculator available online. Alternatively, you can manually calculate the required shock using the compressed and extended lengths.
Suggested Shock for a 2 Inch Lift
A common question that arises when lifting a vehicle is: Do you need new shocks for a 2-inch lift? The answer is yes; new shocks are usually necessary. Stock shocks often cannot accommodate the altered dimensions resulting from a lift, as the extended length of the vehicle will vary significantly.
You can choose any shock that has dimensions close to the previously mentioned lengths. One recommended option is the RCD / Bilstein Toyota Rear Shock #F4-BE5-B110-T5, which features an extended length of 27.28 inches and a compressed length of 16.34 inches. This shock is well-suited for a 2-inch lift, but always take the time to measure your vehicle first and select shocks based on its specific requirements.
Why Choosing the Correct Shock Size Is Important
You’ve learned the steps to measure shock lengths for a 2-inch lift, and it might seem like a tedious process. However, skipping this can lead to choosing the wrong shock size, which can have significant drawbacks. Here are some potential issues that can arise from selecting the incorrect shock:
- Problems with the piston, such as piston slap in Jeep models, may occur due to incorrect shock sizing.
- Damage to the upper and lower shock mounts can happen when the wrong shock is used, as it won’t adequately absorb impacts.
- Leakage in the cylinder head can result from the constant stress of using an inappropriate shock.
- The shock absorber may reach full compression before the suspension fully extends, a condition known as Bottoming Out.
These are significant risks associated with using incorrect shocks. Therefore, it’s essential to take accurate measurements before purchasing shocks after lifting your vehicle.
Frequently Asked Questions (FAQs)
Do I need different shocks with a lift?
Yes, different shocks are necessary when you lift your vehicle. The shock size is directly tied to the extended and compressed lengths, which change when the vehicle is lifted. Thus, it’s advisable to obtain new shocks that correspond with the accurate measurements post-lift.
What is the shock ratio?
The shock ratio refers to the relationship between shock travel and wheel travel. This ratio indicates the amount of force required to extend and compress the shock. The first number in the ratio represents compression, while the second indicates extension.
Do new shocks make a big difference?
Absolutely, new shocks can significantly improve your vehicle’s performance. Shocks are crucial for stability during braking and in response to sudden movements. Installing new shocks enhances braking efficiency and overall handling, allowing for smoother stops during emergencies and boosting driver confidence.
Conclusion
This comprehensive guide has addressed your question: What size shocks are suitable for a 2-inch lift? I trust that you now have a better understanding of the topic. Remember to be meticulous and follow the outlined procedures when selecting your shocks. Prioritize quality over cost when purchasing shocks, as they are vital for safe driving. Ensure you choose the correct shock sizes to guarantee your safety on the road.
