MORE ABOUT THE VERTICAL SPINNER UHMW FRONT ARMOR:
What it is / Who it’s for
The FingerTech Viper Vertical Spinner UHMW Front Armor is a replacement front panel designed exclusively for Viper robots equipped with the Vertical Spinner Add-On. With its precision cutout, it allows clearance for the vertical weapon while still providing the same lightweight, high-impact protection that UHMW is known for. This part is ideal for competitive builders running a spinner configuration who need maximum defense without sacrificing speed. The Viper Vertical Spinner UHMW armor upgrade is a dramatic improvement over the polycarbonate front armor.
How it works
This Viper Vertical Spinner UHMW armor upgrade replaces the standard polycarbonate front panel with a 3mm UHMW polyethylene sheet, engineered with a cutout to accommodate the vertical spinner blade. UHMW absorbs impacts and deflects weapon hits without shattering, protecting the chassis and internals during combat. Despite its toughness, it is lightweight, ensuring your Viper retains the agility required in the arena.
What’s included / What you’ll need
The package includes one UHMW Front Armor panel with vertical spinner cutout. Installation requires basic hand tools, and depending on your setup, you may need mounting hardware. Standard mounting uses four 0.50″ 6-32 button head screws (not included). A 5/64in hex wrench is typically required for these screws. Align carefully and secure all fasteners to ensure reliable performance in matches.
Why this part?
Upgrading to UHMW armor dramatically increases durability without adding excess weight. With its dedicated spinner cutout, this panel prevents interference with your weapon system while shielding your Viper from frontal hits. For teams focused on maximizing both offense and defense, this is the essential upgrade for a spinner build. The standard UHMW front armor is available separately for Lifter, Horizontal Spinner, and Tail Spinner configurations.
Safety & best practices
Inspect your armor regularly for cracks, gouges, or loose mounting points. Always tighten all screws before each match. While UHMW is extremely resilient, no armor is indestructible—regular maintenance keeps your spinner configuration battle-ready.
Installation
Installation is simple: tighten the four screws that attach the chassis to the faceplate. Be sure to orient the armor correctly—the asymmetric screw pattern and cutout must align with the top of the Viper and the vertical weapon clearance. For reference, check the product photos in the gallery.

How does UHMW compare to polycarbonate in durability?
UHMW is more impact-resistant and lighter than polycarbonate, helping your robot stay agile while providing stronger defense against weapon hits. "UHMW's light weight compared to steel, along with its high resistance to wear and abrasion, made it the perfect material for the robot's armor. Unlike steel armor, which does not absorb impacts well and will not stop the robot from moving when hit, UHMW armor can absorb the impact of an opponent's spinning blades." - Interstate Plastics website
What tools are needed for installation?
Basic hand tools are required. Standard mounting uses 0.50" 6-32 screws with a 5/64in hex wrench. Additional hardware may be needed depending on your robot’s configuration.
How should I maintain the armor?
Inspect the armor regularly for cracks, gouges, or loose mounting points. Tighten screws as needed to ensure consistent performance and protection in competition.
