Will not fit or work properly without the control arm upgrade. Only Lift up to 2.5" will work without the upgraded control arm.An alignment is always recommended after altering the height of your vehicle.Our Pro-Billet series full lifts are designed to accurately lift and level your truck for that more aggressive look over stock. Complementing our rear blocks are the differential shims, specially engineered to help correct the pinion angle of your vehicle back to factory specifications. An incorrect pinion angle can cause driveline vibrations when driving at speeds, and will severely shorten the lifespan of the differential pinion bearing. The differential and skid plate drop kit is highly recommended for 4WD model trucks with independent front suspension. This kit will lower your front differential and skid plate to reduce the excess wear on CV joints and axles while adjusting the skid plate location preventing any damage to your trucks components. Each front component of this kit is machined from 6061-T6 aircraft aluminum, then an anodized coating is applied to protect from rusting. We complete this kit with our high grade hardware and extended OEM spec U-bolts keeping you’re parts safe and secure.
