Which King Springs?

I'm wondering how to swap springs on a Tacoma. For example, when looking at King springs it has 2.0, 2.5, 3.0, and 3.75 springs. I figured that this number corresponded to the inches of loft that you wanted, but then it has a lot of other information. For example, 3.0x14x250 and is for 2.5 shock bodies. The last number is the weight per inch, but then the first number is the inches lifted? And what's the middle number? Also, what's a shock body?

 

3.0x14x250 (using as an example)

3.0 Inner diameter of coil spring
14 Length of coil spring
250 Spring rate

 

So can I choose any diameter and length, or which diameter and length does the Tacoma use? If I use a longer spring it lifts the vehicle?

 

3.0 x 14" x 700lb is pretty standard. Long spring wont fit and is not the main way to get lift.

May I ask why you are looking at springs and what your overall goal is? Typically the spring is bought as a pair with the shock (aka a coilover). In that case you typically only need decide on whether you want a 600, 650, or 700 lb/in spring. Length and diameter are already figured out for you by selecting the make, model, and year of your truck.

 

It sounds to me as you are trying to put King springs on stock (or similar) suspension to achieve lift. This will not work. These type of springs are made to work with aftermarket coilovers. You should be looking at OME springs or similar.

 

Yes, that was my goal, to swap the stock springs with King springs with extended travel to achieve a lift.

 

It's not the main way to get a lift? I've been reading that a coilover with an extended spring is the optimum way to get a lift as a spacer limits downtravel and a coil spacer limits uptravel.

 

On something like the Rough Country 6" adjustable vortex coilovers is the lift obtained through the extended springs? Or does it even have extended springs? Or does it use stock length springs and just stretches them to get the 6" lift?

 

This will not work. You will have to replace the entire coil-over with something that lets you achieve your desired result.

 

I think you are misunderstanding. Yes an extended spring (along with spring rate) like OME springs do provide the lift when using a strut assembly such as a Bilstein 5100. If you are using a coilover such as King or Fox, lift is achieved with preload on the spring. Generally, the spring length on a coilover is a set length based on the manufacturer specs. Lift is then achieved with a combination of preload and spring rate based on the weight of your truck. These 2 setups are completely different in concept.
