New - now includes ultra strong TCT free floating pivot bushings that are self lubricating and eliminates friction. ReadyLIFT 69-3414 4" SST Lift Kit is designed for the 2014-2018 GM 1500 4WD & Z71 trucks. ReadyLIFT 69-3414 4" SST Lift Kit combines many of the great features of our time-tested and very popular 4" SST Lift Kit for the 2007-2013 trucks with new innovative features. Some features implemented into this system include a completely different differential drop mounting system which utilizes machined billet circular spacers which allows for just the right amount of differential drop without interfering with the rear-mounted electric steering rack. Additionally, a rugged skid plate accompanies our differential drop system. Our 4" SST Lift Kit uses the heavy duty ball joint found on the GM 2500 HD series trucks -- these ball joints are vastly superior and are already installed into the tubular steel upper Control Arms provided in the kit. But that's not all! This kit also includes premium TCT UCA inner bushings and new washer backing spacer sleeves which greatly prolong the life of the bushings. Our engineering testing has shown this 4" SST Lift Kit is extremely versatile and strong allowing the customer to install up to a 33X11.50 tire (max) on 5.25" backspacing wheel. The kit is for use on trucks with the factory Aluminum or stamped steel upper and lower Control Arms. Not for use on trucks with cast steel upper Control Arms. Z71 standard suspension okay. NOTE: The ReadyLIFT 69-3414 SST Lift Kit is designed for use with Aftermarket Wheels with a backspacing of 5.25". If you intend to run the stock wheels with an aftermarket larger tire, a wheel spacer is required to prevent the tire from touching the control arm at full-locked turn. ReadyLIFT has developed a CNC-machined billet Aluminum wheel spacer 10-3485 for use with factory wheels. To run the OE/Factory wheels AND tires, you will need to use the ReadyLIFT 1/2" Billet Wheel Spacers. Note: Use of Auto 4 Hi feature not recommended.
