  Swift Springs like to believe that all suspension spring manufacturers try their best to achieve these 4 factors. Top suspension tuners know that these 4 factors play an intricate role when considering the effectiveness of the suspension coil spring.The lightest in weightThe highest durability against loss of spring heightThe largest amount of strokeThe most consistent spring rate throughout the strokeSurely you have read some spring manufacture’s catalogs before, and you have read that they all claim to have the 4 factors listed below.Priorities that Swift Springs always have in mind when they develop suspension springs. Swift Springs parent company, Tohatsu, has been winding industrial springs since 1924. Tohatsu then decided to get in to the auto racing market in 1996. Based on long-time experience dealing with coil springs, they came up with one goal: “We must make the product that will revolutionize the ones they see on the market now.” Keeping this goal in mind, they went back to the basics of coil spring design and asked themselves what is the most important factor that they would need to consider on this new project.

The answer?open-wheel

Maintaining tire grip is the key to faster times and suspension springs take on an enormous portion of this task!

All Springs are not created equal, the diameters and spring rates can be similar, but the process of manufacturing springs plays a huge factor in how they will perform. Through the extensive knowledge of Swift Springs in performance springs, they have perfected the process of manufacturing springs that will outperform the competitors.

With this in mind, Swift Springs set out to produce a new material for coil springs: a proprietary steel alloy they call “HS5.TW”. This material was created in order to maintain the 4 factors listed above, as well as achieving the fastest reaction speed possible to get compliance on road surface conditions. Swift Springs are created with proprietary winding methods, as well as some other trade secrets focused on ensuring their springs separation from the standard market.

In the time since Swift Springs officially opened its doors in 1997, Swift Springs has dealt with many world class race teams in multitudes of different races including road racing, rally, off road, drift, autocross, pavement and dirt oval track, motorcycles, and more. Swift Springs has lifted many racers to a podium finish, and is still continuing to do so. With so much experience behind them, they feel confident that their springs will give you a leg up in any kind of race you participate in.

Try Swift Springs on your vehicle, and experience what many racers are talking about. We strongly believe that you will feel the difference just like every other racer, and you might even wonder why you didn’t try it sooner.

Note: Some of our racers are using Swift Springs on 2 corners only, but to achieve the best results from Swift Springs, we highly recommend using them in all corners of the vehicle due to the very different characteristics of Swift springs.
