For a limited time, get two ECS Heavy Duty differential bushings FREE with the purchase of our Dual-Mount Differential Cover Kit—the ultimate rear-end upgrade for your high-output E30 build. Engineered for strength, cooling, and reliability, this kit is the go-to solution for enthusiasts pushing their car on the track, drift events, or the drag strip.

Turner Motorsport Heavy Duty Dual Mount Differential Cover – E30

Stop worrying about weak factory differential mounts! The OEM E30 differential cover has only one mounting point, which can fail under high torque or boosted applications. Turner’s dual-mount billet aluminum cover solves this problem by adding a secondary mounting ear secured to the chassis via a billet plate and sheet metal bracket—either bolted for easy installation or welded for ultimate rigidity.

Crafted from 6061-T6 billet aluminum and finished with black hard coat anodizing, this cover is 30% stronger than stock and engineered for maximum durability. It also features large CFD-optimized cooling fins and a built-in air duct to reduce fluid temperatures, ensuring consistent performance and long fluid life. Optional -6AN fittings allow integration with an external cooler, and a 1/8 NPT port supports fluid temperature monitoring.

Key Features:

Dual reinforced mounting points with integral sheet metal bracket and billet plate for extreme durability

Secondary mount can be bolted or welded to chassis for added rigidity

Large external fins designed via CFD for efficient heat dissipation

Integrated air duct for improved airflow and fluid cooling

Breather system to vent pressure properly

1/8 NPT sensor port for real-time differential temperature monitoring

Maintains compatibility with OEM, aftermarket, or performance E30 differential bushings

Accommodates large rear sway bars and upgraded suspension setups

Removable air duct allows easy access to fill/drain plugs and sensor bungs

ECS Heavy Duty Rear Differential Bushings

Factory rubber bushings are soft, allowing unwanted differential movement that creates a disconnected feel, excess noise, and reduced performance. ECS Heavy Duty rear differential bushings solve this problem with a stiffer HD 70D rubber compound and aluminum center sleeve, locking down your differential while keeping NVH levels manageable for street driving.

Benefits:

Enhanced Responsiveness: Reduces deflection for a more direct drivetrain feel

Street & Track Friendly: HD rubber absorbs vibration but remains firm under performance conditions

Replaces Weak OEM Mount: Ideal for aging or cracked stock bushings

Easy Installation: Precision-manufactured to OEM specifications for a direct bolt-in fit
