102C/108C AND 108EXP SPRINGS FREQUENTLY USED. Color: Gold - Spring Dia.: 2" - Outside Spring Height: 3-1/2" Wire Dia: .207 - # of coils: 6 - Lbs Tension when compressed to height of: 1-1/8": 296 - 2-3/8": 129 - Rate of Tension increase per additional inch of Compression: 123. Actual tensions of springs vary from poundages and rates listed herein which are only COMET spring tension objectives. Certified spring tensions would cause springs to be significantly more expensive. Industry standards for springs permit an initial variance of +/- 10%. To "pre-load" these springs for greater initial tension, up to 3 spring shims (part # 203849) may be used with most of them. "Bottoming out" of a spring coil upon coil even once will hasten its deterioration so avoid using 3 shims if the "bottoming out" condition should result.
