Arlen Ness 320-109 Monoblock Axial 6-Piston Brake Caliper, Left-Hand, Gold
Regular price $529.95 USD
Category:
Upgrade braking performance with the Arlen Ness 320-109 Monoblock Axial Brake Caliper. Designed for left-side applications, this gold-finished caliper combines a rigid one-piece construction with precision-machined aerospace-grade billet aluminum. The monoblock design eliminates flex points commonly associated with multi-piece calipers, helping improve hydraulic efficiency and deliver a more consistent braking response. Its six-piston differential-bore configuration uses optimized piston diameters to balance pad pressure across the rotor for smoother engagement and a more linear lever feel.
The Arlen Ness 320-109 features optimized internal hydraulic routing to promote consistent clamping force during high-load braking conditions. Its single-piece construction also eliminates the potential leak paths associated with two-piece caliper designs, supporting dependable performance and long-term durability. Sculpted external surfaces and integrated cooling fins help manage operating temperatures by improving heat dissipation, which can reduce brake fade during demanding street or performance riding.
This left-hand axial caliper is compatible with both ABS and non-ABS applications, making it a versatile upgrade for properly equipped braking systems. The package includes a bleeder screw, banjo bolt, and high-performance sintered brake pads. The included pads feature dual relief slots designed to help evacuate heat and clear debris from the braking surface. Finished in gold for a distinctive appearance, the Arlen Ness 320-109 combines high-strength materials, carefully engineered fluid control, and included installation hardware for a comprehensive braking upgrade. Verify mounting configuration, rotor compatibility, and application requirements before installation.
