Wilwood 120-9705-SI DynaPro Forged Billet Brake Caliper Lug Mount - 5.25

The Wilwood DynaPro Lug Mount forged billet caliper delivers pure race technology with exclusive performance enhancements for competition and show applications. Featuring a sleek profile with fully detailed machined finish, this caliper combines superior strength with advanced engineering.

Stress-Flow Forged Construction:

Manufactured from premium grade billet using stress-flow forging technology, which realigns the metal's grain structure within the body contour. This process produces substantially greater strength compared to standard machined billet components. The FEA-generated body design incorporates a fortified radial transition that eliminates steps and shoulders between piston housings and bridges, significantly increasing resistance to deflection and body separation under load.

Performance Benefits:

• Reduced structural deflection and fluid volume displacement for increased clamping efficiency
• Less pedal travel with firm, responsive pedal feel
• Heavy wall stainless steel pistons resist corrosion and slow heat transfer
• Enhanced piston strength provides efficient clamping even at high pressures from power boost systems
• Center bridge bolt kit included (SI models) for maximum resistance against body separation

Key Features:

• Quick-E-Clip pad retainers support 7812 type brake pads from the top for fast service without caliper removal
• Slimmer profile design fits tight clearance applications
• SRS bridge plates eliminate bridge wear from pad gouging and extend caliper service life
• Spring-loading action eliminates pad rattle and dampens vibration harmonics that cause squeal
• Internal fluid passages with four corner bleed screws allow mounting in any position (front, rear, left, or right)
• 5.25" lug mount configuration
• Side inlet design with center bridge bolts included

This DynaPro caliper provides outstanding stopping power with structural integrity proven through deflection and volume displacement testing, making it ideal for high-performance braking systems.
