• Improves weight transfer. • Frees up suspension for more consistent, repeatable chassis tuning. • Precision-machined to tight tolerances, providing consistent resistance throughout the travel of the ball joint, to deliver consistent performance. • Road inputs are controlled more effectively by the shock and spring instead of the tire, which improves traction. • Removes suspension bind and allows shock & spring to have more precise wheel control. Position: Lower Ball Joint Type: Press-in Degree of Taper: 10 degree Overall height: 5.00" Fits most aftermarket tubular or strut type lower arms on 1973-95 Chevy Pickup, 1971-76 Impala, many Street and Hobby Stocks, and common on Modifieds to raise roll center.
