Unlike our competitors who offer you low prices for inferior products, we build products that lift and level your vehicle without compromise. Cutting corners is awesome when driving your truck, but not when manufacturing, buy right, choose Supreme.

We are proud to introduce you Supreme's New 2019 Lightweight Steel Blocks for Rear Lifts. Developed and rigorously tested by in-house engineers, our blocks are precision machined from ONE Piece of Steel! Using heavy-duty GMAW seam and fillet welding processes we've made this block superior than those other blocks that are welded on all 4 sides. Our Heavy Duty Steel rear blocks are constructed with one reinforced center pin and a 1/4" Thick CNC plasma cut center support structure to ensure stability, perfect fitment and easy installation.

NOTES: An alignment is always recommended after altering the height of your vehicle.
