Assist springs
Assist springs have two functions. The first is the spring adds a progressive rate to the initial portion of the stroke. This progression can add increased comfort is used on a daily driver coilover setup that has stiff springs installed. It provides racers added softer spring rate progression. Once the assist crushes, the normal spring rate will take over.
The second job is the same as helper springs. They prevent the loss of traction during rebound, and extreme cornering.

Assist springs are designed to repeatedly be fully crushed. Every assist spring crushes to the same height. That allows drivers to change assist springs without resetting the spring perch on coilover without changing ride height.

Helper Springs
Helper springs prevent dismounting of springs from perch on coilover
without changing spring rate.

Swift helper springs are specially designed to provide minimal effect on spring rate. Using helper springs allows the spring to stay firmly on its perch when the shock has negative or zero load. Driver should use helper springs if they experience springs coming loose from their perch and/or they can not preload the main spring because of car height issue.


Metric Coilover Springs
Less unsprung mass, more stroke, increased handling.
The only thing you will be loosing is track time.

Swift's flagship products that made Swift a regular name in the worlds most famous racing series. These products have been the child for over 80 years of industrial spring experience. Hundreds of engineers proven concepts and theories were materialized in this springs development. The end, the product is the lightest, most durable, and the most linear spring rate on the market.

While most track racers have already began the ritual of swapping their springs, many swap from one brand to another let you notice the stiffness only as being either softer or harder. What if a spring could change other dynamics, such as a noticeably lighter unsprung mass, smoother weight transferring, better ride quality, lower tire temperature, and increased ability to anticipate vehicle reaction? Like most racers, Swift team hates to hear “what if”, so they built the “what if” into reality.

All of the Swift Springs are made with our exclusive material called H5S.TW.
Without this specially designed material, our light weight spring design does not exist.

Our metric coilover springs are measured and rated in the metric system. The metric system is used widely in the sports compact market, and therefore we want to provide an easy understanding for the suspension tuners.

We offer the widest range of metric coilover springs from 3kg through 34kg in various inner diameter and springs length.
The diameter, length, and rates that we offer will cover users with a need of a daily comfortable commute, up to world class racing machines. Which ever suites the needs of the individual!
