In stock form this truck has only 2" of droop travel in the front suspension, not enough to provide a good ride quality for anything more than going through a gutter or small dip. Cognito has figured out how to maximize the potential of the front suspension travel by determining the precise amount of spacer that can be added to the stock Multimatic DSSV front shocks in order to increase the droop travel to just over 3". This 50% increase in droop travel allows for more compliance through bumps and dips without getting the harsh feeling of the front shocks topping out.

• Precise thickness to maximize droop travel
• Anaodized blue to match the DSSV shocks
• 1-hour DIY install time
• Billet Aluminum

The 2023 Canyon AT4X and Colorado ZR2 already have a 1” taller ride height than the above mentioned, and this was done by GM via preloading the spring more. These models have 3-1/2” of droop travel, 1” less than the above but 1” more ride height than the above. Therefore, the included preload ring spacers will not be used on these models since we do not want to reduce droop travel any further, and they would not fit the Multimatic DSSV struts anyway. The overall length of the front strut is the same as the AT4/Trail Boss, so we can increase that length with the included billet strut spacers to gain 1” of additional front ride height on the AT4X/ZR2 models. This model will still have a bit of nose down rake, since it also has a factory lift block in the rear. The net result is a more level stance with a factory ride which is really good with the Multimatic DSSV dampers.
