Product Details: Add strength and rigidity to the critical area around your upper coil buckets, track bar mount, and motor mount. Brings the front rails to ~1/4” thick, making the unibody thick enough to weld custom bracketry to without burning through and strong enough to handle tons of abuse. Doubles as steering box mount reinforcement with pre-cut holes for the mounting bolts. Comes in three pieces per side requiring less disassembly of your front end to install. Slotted to allow easier and closer fitment against the unibody. Slot welding helps distribute stresses throughout the entire reinforcement plate. 3/16” thick laser cut plate.
