iK Competition Products
Introducing ik competition springs.

Exhaust Header Springs | Swivel End Springs | Pipe Mount Springs | Side Pod/General Springs | Yamaha Clutch Springs

Designed for high performance and durability in the crucible of competition. Whether you are racing at the National level or a weekend warrior, iK competition springs will help maximize the performance of you & your kart.

iK Competition Springs are made in the U.S.A. - Aerospace Stainless & Military spec

iK Competition Products for Kart Racing

The Problem: Current Material and Design Most (all) current springs are manufactured from music wire (high carbon steel). Music wire has poor corrosion resistance, which can effect spring performance in adverse weather conditions. Many times, these springs are plated to improve corrosion resistance but often, the plating process engenders durability issues as they are not prepared properly for long-term use prior to plating. More importantly, music wire has a maximum service temperature of 250°F and can be negatively effected at temperatures as low as 185°F. As a spring nears its maximum service temperature, the heat promotes spring set, damage to the spring, and is detrimental to the relaxation of the spring. Additionally, the material used limits the design and angle of the spring hook radius, necessitating and ensuring a repeated fail point (visible at the bend where hook end meets coil) in most all traditionally designed, widely distributed kart springs.

iK Competition SpringsThe Solution: iK Competition Springs Each spring is manufactured from certified aerospace specification 17-7ph stainless alloy. After winding, the springs are fully heat-treated, stress relieved and passivated. Although our aerospace stainless needs no plating we do passivate our springs in order to decontaminate and cleanse the metal at a microscopic level post-winding combating the dehabilitating effects of winding on the metal. This step in our engineering process, combined with the high strength, corrosion resistance, and Rockwell of C50 inherent in 17-7ph stainless translates to our springs withstanding a maximum service temperature of 700°F. Because of the quality of our materials and process, our springs can be stretched for use up to double their resting length with no yield in recoil, offer consistent performance when heat becomes a factor, such as with header/exhaust springs and clutch springs, and are designed to minimize key fail points in current karting spring designs. Our full product line undergoes a 96-hour military stress test with no resulting corrosion, loss of strength, or durability.

  • Increased durablity - prevents sudden failures at key moments
  • Heat resistant - perfect for exhaust applications
  • Weather resistant - important for us here in the rainy Northwest
  • Maintains "memory" - up to double their resting length with no yield in recoil
  • Quality Aerospace materials - designed & manufactured here in the U.S.A.

Don't let a broken spring lose a race for you. To many races are lost from broken exhaust springs causing pipes to fall off, or broken springs on side-pods allowing the pod to come off.

Exhaust Header Springs - C and Triangle End

C-End Exhaust Spring
iK Competition Springs
C-End Exhaust Spring

iK C-End Exhaust Spring -- $4.50

  • 55mm/2.15" - Universal exhaust header application. Fits IAME/Vortex/Rotax TaG Engines.
  • Aerospace 17-7 stainless steel, non-responsive to heat under 700 degrees
  • Maintains tension while stretched up to double resting length with no yield
  • Hook-end design combined with better material to remove fail points evident in mainstream springs

Triangle-End Exhaust Spring
iK Competition Springs
Triangle-End Exhaust Spring

iK Triangle-End Exhaust Spring -- $5.00

  • 65mm/2.5" - Universal exhaust header application. Fits IAME/Vortex/Rotax TaG Engines.
  • Aerospace 17-7 stainless steel, non-responsive to heat under 700 degrees
  • Maintains tension while stretched up to double resting length with no yield
  • Hook-end design combined with better material to remove fail points evident in mainstream springs


Designed to remove stress risers that can lead to breakage. The 17-7 material insures that, even in high heat, the springs will retain their tension to maintain a proper seal between the header and exhaust pipe and can be stretched over a wider range of use without compensating or inhibiting their performance.

Exhaust Header Springs - Swivel End

Swivel End Exhaust Spring
iK Competition Springs
Swivel-End Exhaust Spring

iK Swivel-End Exhaust Spring -- Price TBA

Available early 2015

Designed to remove stress risers that can lead to breakage. The 17-7 material insures that, even in high heat, the springs will retain their tension to maintain a proper seal between the header and exhaust pipe and can be stretched over a wider range of use without compensating or inhibiting their performance. The added benefit of the swivel spring is ease of use as the swivel hooks enable a full range of placement.

Side Pod/General Use Extension Spring - Triangle End

Side Pod Extension Spring
iK Competition Springs
Side Pod Extension Spring

iK Triangle-End Spring -- $5.00

  • 65mm/2.5" - Universal exhaust header application. Fits IAME/Vortex/Rotax TaG Engines.
  • Aerospace 17-7 stainless steel, non-responsive to heat under 700 degrees
  • Maintains tension while stretched up to double resting length with no yield
  • Hook-end design combined with better material to remove fail points evident in mainstream springs


 

Designed to remove stress risers that lead to breakage and, although not subjected to high heat when used on the side pod, the high strength of 17-7 stainless will minimize breakage whether by wear or contact. The corrosion resistance adds to the durability and lifespan of the spring while the material quality nets a larger range of use when stretching the spring to different lengths with no worry of losing recoil or strength.

Pipe Mount Springs - with Finger Loop

iK Pipe Mount Spring with Finger Loop -- $12 ea.

  • Swivel head on finger-loop end, and oversized end loop for easy mounting & removal.
  • Aerospace 17-7 stainless steel, non-responsive to heat under 700 degrees
  • Hook-end design combined with better material to remove fail points evident in mainstream springs

Designed to remove stress risers that can lead to breakage. The 17-7 material insures that, even in high heat, the springs will retain their tension and can be stretched over a wider range of use without compensating or inhibiting their performance. Finger loops are added for ease of use and application.

Yamaha Clutch Springs - for Yamaha KT100

Yamaha Clutch Spring
iK Competition Springs
Yamaha Clutch Spring

iK KT100 Yamaha Clutch Spring -- $4.95

  • Identical springs all produced to measure within 1/1000th.
  • Aerospace 17-7 stainless steel, non-responsive to heat under 700 degrees
  • Uniform & Consistent equals better performance and no more tedious spring matching
  • Longer lasting more even load properties
  • Fits Horstman and Patriot clutches

These springs will work with all popular clutches currently on the market. Designed to minimize coiling stress; they are meticulously produced to insure consistency of all dimensions, consistent loads & excellent perpendicularity properties. If the spring does not stand straight on a flat surface, it is impossible for the springs to have consistent load properties when installed. 17-7ph insures that spring and clutch function will not be adversely affected by high temperatures or adverse weather conditions, both common factors in everyday kart racing.
