Straight Type Springs

  • We use SWOSC-KV silicon chrome metal (JIS standard) to pursue the maximum quality of high tension and endurance for all standardized springs
  • Stable quality, endurance, and high performance is maintained by special procedure (cooling formation)
  • The straight type springs are measured by inner diameter and, specified spring seat is required
  • The outer diameter changes with alignment

Taper Type Springs

  • These are standardized springs which have been developed to adopt with original upper mounts for original double wishbone and multi link suspension system
  • Ideal for N1 and other vehicles whose upper mounts cannot be replaced under regulations
  • By eliminating the upper spring seat, we have achieved low cost and adequate bump stroke
  • It eliminates the damage to upper mount and other noise by maintaining same force input positions as original products
  • As it is tapered, spring stroke can be maintained better than the straight type with same spring coefficient and length

Helper Spring

  • By setting 2 springs in a series, variable spring rate can be achieved
  • It gives unlimited setting range with wide winding point weight set ups
  • The A spring is a series twin spring, and the B spring can be selected from straight type with I.D.70mm or tapered type springs. A variable spring is achieved through changing over from original spring rate to B spring rate.
  • The spacer spring seat is necessary for installation with the A spring

ALL TEIN STANDARIDIZED SPRINGS ARE SOLD AND PRICED PER SPRING FOR A COMPLETE SET OF 4 YOU NEED TO ORDER QUANTITY 4
