Spring - Front - BC Racing 62-200-6 - Contact BC Racing

BC Racing utilizes 3 main spring designs: linear, S-barrel, and V-barrel. All of these springs have their intended uses in our coilover systems depending on the OEM suspension design, as well as the design of our kits. Every one of our springs is made of SAE9254 steel material and utilizes a Zinc coating under the outer powder coating to ensure rust does not penetrate the metal of the spring and compromise performance/reliability. We have springs available in as small as 120mm length and as great as 300mm length. Spring rates are available in select spring lengths from 2KG up to 22KG.

The linear springs we offer cover a wide variety of suspension setups available. The liner spring is an industry standard 62mm I.D. (inner diameter) available in many different lengths and rates to suit our customers needs. For many independent rear suspension vehicles, we utilize an S-Barrel spring. An S-barrel spring uses the same 62mm I.D. measurement on both ends but in the center the winds are bowed out to allow for greater spring stroke with the use of a shorter spring. The S-barrel is perfect for the rear of most independent rear vehicles simply because when the spring
compresses over rough terrain, the winds are less likely to touch and create noise. For both linear and S-barrel springs, there is a set of three white numbers on the spring referring to the part number and specs of the spring. The rubric to decipher this is:

First set of numbers- Refers to the I.D. of the spring on both sides
Second set of numbers- Refers to the static length of the spring in mm
Third set of numbers- refers to the spring rate in Kgf/mm
