2007 -2014 Avalanche, Silverado, Tahoe and Suburban 4″ Calmax control arm set (Upper and Lower)

2007 -2014 Avalanche, Silverado, Tahoe and Suburban 4″ Calmax control arm set (Upper and Lower)

Update: *2015 Silverado’s come from the factory 2 ways, one with cast iron steering knuckle’s and one with cast aluminum steering knuckle’s. Don’t worry, we got your back! If you have the cast iron knuckle your in the right place. If you have the cast aluminum knuckle you need CA2515-4.
Have cast cast iron spindles? You’re in the right place! 
The 4″ Calmax Control kit gives you the freedom to lower your ride without having to worry about wheel clearance (even the factory spare) or alignment issues. You just can’t do that with coils or spindles! Using your factory coil and spindle you still have the full suspension travel Chevy built in, and you can diddle with your alignment for performance purposes! Running expensive tires? No problem you have control of your suspension. Both upper and lower control arms are used to set the alignment and keep the ball joint angles optimized, plus lower a full four inches! A unique DJM feature! This kit is the only way to get past 2″ of drop and keep all of your travel, ride quality, and normal tire wear without any negative consequences.
