Energy Suspension’s Rear Differential Mount Bushing Set is engineered for your vehicle. Constructed from proprietary Hyper-Flex™ polyurethane, these high-performance bushings replace the OEM rubber mounts to significantly reduce differential movement. By tightening the connection between the rear differential and chassis, they enhance power transfer, improve traction, and provide more consistent handling during acceleration, cornering, and braking. Designed for both daily driving and spirited performance, these bushings maintain alignment under load, resist wear from heat, oil, and road debris, and outlast standard rubber mounts. Available in red for a bold, performance-oriented look or black for a stealthy OEM appearance, this upgrade ensures rear drivetrain stability and sharper overall vehicle response.
Energy Suspension builds performance polyurethane suspension bushings and chassis components designed to replace soft, worn factory rubber. Their Hyper-Flex® material is aimed at improving steering response, handling consistency, and durability—ideal for enthusiasts who want a tighter, more connected feel on street or track.
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
