Polyurethane Rear Subframe & Rear Differential Mount Insert Kit

     Put the power to the ground and enhance your vehicle's driving dynamics with ECS Tuning Rear Subframe & Rear Differential Mount Insert Kit.

Enhance your vehicle's driveline rigidity and response time for harder launches and faster 0-60 times all while reinforcing old, worn out bushings. By locking down the rear subframe and rear differential, rear suspension geometry is maintained and driveline rigidity is improved, resulting in a more "connected" relationship between driver and machine. Rear suspension feedback is enhanced, rear sway bar upgrades are more effective and a more connected feel between shifter and driveline is created. 

Featuring a combination of polyurethane and billet aluminum, these inserts take up the void's found within the rear differential and subframe mounting bushings and do not excessively increase NVH. In addition, they do not require removal of the OEM bushings, making installation simpler than a full replacement. 

PART DESIGN

-- The Problem: --

• The factory rear differential and subframe are prone to excessive movement which reduces power transfer reaction time and reduces traction. The slop from the differential and subframe are both caused by voids within the OEM mounting bushings and aged/worn bushings. This slop translates to a mushy transfer of power from the driveshaft to the rear tires and disconnected feeling rear suspension with unintended suspension & drivetrain geometry leaving room on the table for much improvement.

-- The Solution: --

• Our ECS Rear Differential and Subframe Bushing Inserts take up the voids found within these mounting bushings while simultaneously reinforcing the bushings if they are aged or worn out to increase traction, cornering performance and rapidly improving power transfer to the rear tires. 

• Two inserts make up the ECS Rear Diff. Bushing Insert Kit: The aluminum insert cap and the polyurethane bushing insert. 

  • The aluminum insert is made from 6061-T6 aluminum for it's strength and lightweight properties. It's black anodized for corrosion protection and features a factory inverted profile to take up the voids within the rear differential mounting bushings. 

  • The polyurethane insert is made from 93A durometer, void-free polyurethane for strength and NVH suppression. Like the aluminum insert, it also features a factory inverted profile to take up the voids within the rear differential mounting bushings to reduce bushing deflection and limit overall slop in the drivetrain. 

• Two key components make up the ECS Rear Subframe Bushing Insert Kit: The polyurethane bushing inserts and the metal retention caps. 

  • The polyurethane inserts are made from 93A durometer, void-free polyurethane for strength and NVH suppression. They feature a factory molded profile to take up the voids within the rear subframe mounting bushings to reduce bushing deflection and limit overall slop in the suspension and drivetrain. 

  • The aluminum retention caps are made from 6061-T6 aluminum for it's strength and lightweight properties. They are black anodized for corrosion protection and properly locate the bushing to keep suspension and drivetrain geometry tight. 

• Each kit includes an OEM TTY (Torque-To-Yield) bolt that is required to be replaced every time it has been torqued and a packet of poly. bushing lubricant to be used during installation. 

PERFORMANCE FEATURES

• By planting the rear differential and rear subframe with our bushing inserts, the rear end is better able to transfer traction to the rear tires by keeping geometry where it's set and allowing the tire to remain in contact with the road.  By removing the amount of slop or "lash" from the drivetrain, sudden torque transfer from the driveshaft to the rear tires is less violent as the parts are held tighter together.  

• Our R&D Team tested an APR Stage 2 tuned, 2015 Golf R (DSG) with a stock rear end against our ECS Diff. and Subframe Bushing Inserts and observed an improvement in the 0-60mph time. It's best "P3 Gauge" recorded 0-60mph time was 3.7000 seconds; now that's launching hard!

• Whether your vehicle is used for street, drag or HPDE, our ECS Rear Differential Bushing Inserts will keep your rear-end planted for improved traction when you need it most. 

PRODUCT DEVELOPMENT​

• Our Research and Development Team reviewed many combinations of rear differentials and rear subframes throughout the model years and punished our bushings on a MK5 R32, MK6 Golf R and a MK7 Golf R to validate their performance and long term benefits. 

• Our ECS Rear Differential and Subframe Bushing Inserts were designed, engineered, tested and quality inspected by our Research and Development team in our Wadsworth, Ohio facility. We ensured the highest level of precision and quality is delivered throughout rigorous long term product testing and leading edge product development methods.
