Color: Black Powdercoat--HOW DO THESE SHACKLES INSTALL ON MY VEHICLEThe rear shackle kits are one of the fastest and easiest ways to change the rear ride height of your vehicle. Lift the rear of the vehicle off the ground, support the axle, and simply swap out your stock shackles with our new shackles.--ARE MY COMPONENTS COATEDAll of our steel components are finished using a proprietary teflon-blend coating. This provides the most durable and corossion resistant finish to withstand even the toughest abuse, on and off-road.--DO I NEED AN ALIGNMENT AFTER INSTALLA wheel alignment is always recommended after any components of a vehicle's suspension have been altered. This include disassembly and reassembly. Having a proper wheel alignment will ensure proper vehicle control during on and off-road driving conditions, as well as help maintain even treadwear over your expensive tire investment.
