Porsche EPR Billet Front Uprights – 964

Included Components:

• (1) 993.038.02 
• (2) 999.053.041.03 - Wheel Bearings
• (2) 993RSRTR - Inner Tie Rods
• (1) 964.008.3PS.BBI - ERP Outer Tie Rods

These no-compromise 964 front uprights from Eisenlohr Racing Products are more than just another billet copy of the RS uprights. The roll center has been corrected and bump steer has been virtually eliminated. The shock mount has also been lowered by 50mm, accommodating lowered vehicles while restoring shock travel and correcting suspension geometry.

The entire upright has been optimized for suspension geometry, strength, rigidity, and weight. Extensive FEA testing was performed to ensure the uprights are significantly stronger than the OE components. Structural ribbing increases rigidity while weight optimization keeps each upright at just 5.45 lbs., despite the added strength and denser material.

The uprights use the OEM wheel bearing and include 6-bolt wheel bearing retainer plates. The OEM plates use only four bolts and are a known failure point in competition applications.
