Metallic Blue secondary spring is heavier than the secondary

spring in the DBW660Y Grizzly kit. It can be used as an

accessory to aid the 660/700 Grizzly 4x4 in serious mud

applications with 28” and larger Aggressive Mud Specific tires.

For trail riding and tires smaller, or less aggressive, the plain

w/pink stripe spring in the DBW660Y kit is better and more

appropriate. Also the stock spring on the 700 Grizzly's would be

better unless using these specific tires. For Grizzly ATV

applications this spring is only for the big aggressive mud

competition tires.
