472-DPSSMBL

Metallic blue secondary spring is heavier than the secondary spring in our 472-DBW660Y Grizzly kit. It can be used as an accessory to aid the 660/700 Grizzly 4X4 ATV in serious mud applications with 28” and larger aggressive mud specific tires. For trail riding and smaller or less aggressive tires, the plain w/pink stripe spring in our 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.

472-DPSSMR

Metallic red secondary spring is for a heavier load rating than the metallic blue (see “components” page for load ratings). For use in 700 Rhino applications for heavier tires 26” and up. Also used for 660 Rhino when running 28” and larger tires. This spring is also appropriate to help with bottom end and midrange response on 660 RHINO applications using heavier stock size, or 26-27 inches tires. Helps slow the initial upshift of the belt and get RPM quicker on initial take off. Also helps with power loss from sand applications.
