Why Choose MaxTrac 900240?

The MaxTrac 900240 brings together several major components required for the corresponding Silverado/Sierra lift configuration. Instead of sourcing the 3" strut spacers, 4" rear blocks, U-bolts, and extended rear shocks individually, this box packages them together for a more coordinated installation.
Two 2900LL-4 rear shocks are included to accommodate the increased rear suspension height, while compatibility with MaxTrac 701935 makes the 900240 an integral part of the intended complete lift system.
