SPL Pro Suspension SPL SSB Z34 Solid Subframe Bushings for Nissan 370Z/Infiniti G37

The SPL Pro Suspension SOLID Series Aluminum Subframe Bushings replace the factory rubber bushings to eliminate subframe free play and deliver precision suspension performance. These CNC-machined billet 6061-T6 aluminum bushings prevent the subframe from deflecting under drivetrain torque or suspension load, maintaining optimal geometry and reducing wheel hop.

Key Features:

• Precision CNC machined from billet 6061-T6 aluminum for an accurate, durable fit
• Slide-in shim system allows quick adjustment of subframe height to fine-tune roll center and anti-squat behavior
• Formula Drift regulation compliant - maintains OEM height while meeting competition standards
• Includes optional rubber isolation washers to reduce noise transfer from subframe to chassis
• Eliminates bushing deflection for improved power transfer and traction
• Made in the USA with precision manufacturing

The adjustable shim system provides tuning flexibility: raising the subframe compensates roll center for lowered vehicles while increasing anti-squat, while lowering decreases anti-squat at the expense of roll center height. Sold as a complete set with all necessary hardware for installation.
