Below is a general manufacturer product group description. Please note the information below is not item specific. Item specifics are above in product details.

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
