What are +2 springs?

[mikec]

It seems from the huge amount I e read that generally all the lifted springs achieve the lift by being firmer, is that right? If so does anyone know somewhere that make +2 but in the standard spring rates? Cheers mike

Not really!! +2 inch spring are longer than standard springs by enough to lift the truck chassis by about 2inches, they are generally firmer to compensate for the increase in ride height. Ground clearance under the axles is not improved by a spring lift, but it allows a larger diameter tyre to be fitted to remedy this. A 2 inch lift will increase the distance that the chassis is above the ground. Not sure about spring rates but an email to you supplier of choice should get you the info you want.

Hope that clarifies it for you!

Ok cheers I read somewhere about the spring being the same. Cheers paul

your kinda both right....

its all to do with the spring rate - or the how stiff the spring is.

there are a few things that can affect the spring rate:-

the length of the spring or the number of active coils,

the diameter of the wire that the coils are wound from,

the material the coil is made from,

and the diameter of coil its self.

So you can have two springs that are the same length but different spring rate.

The stiffer the spring, and the more pounds of load it takes to compress the spring one inch.

So for example to take a set of britpart 2" lift springs and put them on a 90" but also put the same springs on a fully 130, the 90 as it is lighter will more then likely see the full 2" extra lift but the 130 will not. which is of course why they have different lift spring sets for the different models (weights) of land rover.

So it all depends on the manufacturer of the spring as to how they have achieved the greater spring rate

hope this helps
