A set of four V-Maxx primary springs. This will allow you to convert your V-Maxx XXtreme coilovers to a different specification.
The Sport package springs are the ones found on the V-Maxx Classic as well as the XXtreme Sport package coilovers, and have rates of 391 lb/in front and 258 lb/in rear.
The Track Pack springs are the ones found on the XXtreme Track Pack coilovers, and have 505 lb/in front and 336 lb/in rear spring rates.
As with all of our current V-Maxx Sport and Classic coilovers, the front spring is the extended unit that does not require a helper.
The Track Pack springs are not recommended for use with the Classic shocks, as the shocks are not valved for these spring rates. The springs have a 60mm diameter and may not be compatible with other coilovers.
Please note: the Track Pack springs require helpers in the front and often in the rear. If you are starting with a Classic/Sport setup without front helpers, you may want to order some helpers.
