What does 2.5 mean in shocks? The “2.5” in shocks typically refers to the shock’s diameter, often used in high-performance shocks. It doesn’t directly indicate length or travel.

What is the difference between shock length and travel? Shock length refers to the physical size of the shock absorber, while travel refers to the distance the shock can compress and extend within its range.

Do shorter shocks lower my truck? Shorter shocks alone won’t lower your truck’s ride height. Lowering typically requires changes to the suspension components or springs.

What is the difference between shortened shocks and normal shocks? Shortened shocks are typically designed for lowered vehicles and have a shorter compressed length. Normal shocks have standard lengths for stock or mildly lifted vehicles.

Can shock absorbers last 20 years? Shock absorber lifespan can vary widely depending on usage, driving conditions, and maintenance. While they can last a long time, 20 years might be pushing it for most shocks.

Are cheap shock absorbers worth it? Cheap shock absorbers may save money upfront, but they often have lower quality and shorter lifespans. Investing in higher-quality shocks can provide better performance and longevity.

Are foam cell shocks better than gas? Foam cell shocks and gas shocks have different characteristics. Foam cell shocks can be suitable for specific applications, but neither is universally better than the other.

Will replacing shocks change ride height? Replacing shocks alone won’t typically change ride height. Ride height adjustments usually involve changes to springs or suspension components.

Do shocks take time to break in? Shocks may settle and perform optimally after some use, but they don’t require a specific break-in period.

Can shocks go either way? Shocks are designed for specific directions of compression and extension, so they should be installed correctly to function effectively.

What happens if you over-tighten shocks? Over-tightening shocks can damage them or cause them to lose their effectiveness. Always follow the manufacturer’s recommendations for torque specifications.

What does extended length mean in shocks? The extended length of a shock refers to how long it is when fully extended, typically measured from the center of the mounting holes.

Should you be able to compress shocks by hand? Shocks should offer some resistance when compressed by hand, but they shouldn’t compress too easily or feel overly stiff.

Can I use stock shocks on a 6-inch lift? A 6-inch lift typically requires longer shocks than stock to accommodate the increased ride height and suspension travel.

Is it better to lift the body or suspension? Lifting the suspension is generally preferred for off-road performance, as it maintains ground clearance and suspension travel. Body lifts are primarily for aesthetic purposes.

Can I use stock shocks with a 2-inch lift? Using stock shocks with a 2-inch lift may work temporarily, but it’s recommended to use shocks designed for the increased ride height for optimal performance and safety.

Will a 2-inch lift affect handling? A 2-inch lift can affect handling by changing the vehicle’s center of gravity and suspension geometry. Proper suspension setup is essential for maintaining good handling.

How much lift do King 2.5 shocks give? The amount of lift provided by King 2.5 shocks depends on the specific vehicle and suspension setup. It’s best to consult the manufacturer or a suspension expert for accurate information.
