Are Moog coil springs good?

As for the moogs they are still a good spring. I would recommend them for people that want to restore their 4runner to stock height and want a firmer ride for loads or aggressive on road driving. Matched with a firmer front torsion bar you can make your 4runner handle better on the street.

How long do OEM coil springs last?

How Long Do Coil Springs Last? There really is no set timeframe at which coil springs expire. A lot of coils last for the life of a vehicle, while others break down sooner. 2.

What is a constant rate coil spring?

When we talk about variable rates and constant rates, we are referring to the rate of force acting upon the spring, or “deflection.” Constant-rate springs have a uniform rate of deflection because they are the same diameter from top to bottom.

What are cargo coil springs?

They are variable rate springs that change resistance as they compress, and become progressively stiffer as the load increases. Cargo coil springs automatically adjust to changing load conditions to maintain proper chassis height and smooth ride characteristics.

Why are heavy duty coil springs used?

The purpose of automotive coil springs is to absorb a considerable amount of weight for a truck to carry. By reinforcing your truck with Heavy Duty Coils Springs, it will increase its capacity load as well as prevent sagging from the added weight. It also gives a vehicle a 1” lift.

Do coil springs sag over time?

All springs sag with age. The constant load they bear leads to creep within the molecular structure of the metal. Over time, the spring weakens and begins to lose height (coil spring) or arch (leaf spring).

Should coil springs be replaced in pairs?

It’s recommended to replace coil springs in pairs. Over time coil springs weaken, so if you replace only one spring, the left and right springs will respond differently to the road and the left and ride sides may have a different ride height.

When should I replace my coil springs?

Springs typically last a long time and, in some cases, can even last the lifetime of the vehicle. However, that doesn’t mean springs don’t wear and become worn out over time. When springs do reach the end of their lifespan because they’ve lost their resilience or have become broken, ride quality and safety suffer.

What spring rate should I use?

Springs should typically be compressed 25-30% of the free length when supporting the weight of the vehicle.
