Detroit Speed, Inc. QUADRA-Link™ Rear Suspension Kit - (1964.5-70 Mustang - Base Shocks)

Product Code: 041731

Note: If you plan to order a complete rear-end assembly, please order your QUADRALink™ Kit without axle brackets.

This is a great way to upgrade from original leaf spring suspension. Unlike our competitors, our exclusive 4-link geometry design is uncompromised to achieve the best possible handling. The Detroit Speed “Swivel-Link™” (Patent No. 7,398,984) allows the suspension to fully articulate with smooth solid motion with no binding. The best feature is that this is achieved without heim-joints. Heim-joints are noisy and wear out fast. The Detroit Speed, Inc. QUADRALink™ utilizes tuned high-durometer rubber bushings (in place of heim joints or squeaky urethane bushings). The long upper links provide great pinion and u-joint angle control. Contrary to competitors’ kits, our kit utilizes a panhard rod that provides precise and effective rear axle lateral location during hard cornering. The panhard rod is adjustable as ride height changes for roll center control. Also included is a rear sway bar. The sway bar is powdercoated gloss black and includes end links, bushings, and mounting brackets for installation. Don’t settle for anything less than Detroit Speed’s QUADRALink™ rear suspension!
