This all-in-one upgrade offers extreme improvements in strength, fluid cooling, and reliability. Whether you're pushing your car to the limit on the race track, shredding tires at drift events, or fighting for tenths at the drag strip, this differential cover is engineered to keep your drivetrain secure while optimizing overall performance. \u003c\/p\u003e\n\u003cp\u003eStop worrying about breaking your weak differential mounting tabs! The factory E30 differential cover features only one mounting provision. While this may be adequate for your Grandmother's automatic M20 car, it is a guaranteed failure point on your boosted M5X. After years of broken covers, mounting tabs (and dreams), Turner's team of E30 enthusiasts created the ultimate reliability solution! Unlike the OEM cast aluminum cover, this cover is constructed from 6061-T6 billet aluminum, providing a 30% increase in material strength alone. A secondary mounting ear was added to the billet cover to further increase the cover's strength, providing an additional source of stability and driveline shock absorption. The secondary mount is secured to the chassis using a sheet metal bracket and a billet aluminum plate, which can be bolted on for easy installation or welded for maximum strength and rigidity.\u003c\/p\u003e\n\u003cp\u003eAnother drawback of the factory differential cover is its lack of any cooling features. To solve this issue, Turner's differential cover upgrade features advanced cooling technology. Large external fins have been added to the cover, and are optimized using CFD (Computational Fluid Dynamics) analysis to efficiently dissipate heat, reducing overall fluid temperatures. By maintaining a more stable differential temperature, this cover ensures consistent performance and extends the lifespan of your differential fluid. Additionally, a built-in air duct assists in cooling by increasing airflow around the differential, further preventing heat-related failures. For the serious track, drift, and drag strip enthusiast, this cover features optional -6AN fittings. This allows for easy integration of an external fluid cooler if desired. Finally, a 1\/8 NPT port is also included to ensure compatibility with fluid temperature monitoring systems. \u003c\/p\u003e\n\u003cp\u003ePrecision-machined from 6061-T6 billet aluminum and finished with a black hard coat anodizing, this cover is built to withstand whatever you can throw at it! Despite its robust construction, this differential cover retains all OEM mounting features. This means any factory, aftermarket, or performance E30 188mm differential cover bushing can be installed, allowing you to customize this cover to suit your build. Turner's cover also accommodates large rear sway bars, ensuring fitment on cars with upgraded suspension. The removable air duct provides easy access to sensor bungs, fill plugs, and drain plugs, making servicing your differential a breeze. \u003c\/p\u003e\n\u003cp\u003eFEATURES\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHeavily reinforced mounting locations are designed to withstand extreme horsepower, torque, and shock load.\u003c\/li\u003e\n\u003cli\u003eA built-in secondary mount, integral sheet metal bracket, and billet adapter plate make this the strongest E30 differential cover on the market.\u003c\/li\u003e\n\u003cli\u003eThe secondary mount is designed for easy bolt-in installation or can be welded to the chassis for ultimate rigidity.\u003c\/li\u003e\n\u003cli\u003eLarge external fins, designed using CFD analysis, dissipate heat efficiently, reducing overall differential fluid temperatures.\u003c\/li\u003e\n\u003cli\u003eAn integrated breather system to properly vent built-up pressure.\u003c\/li\u003e\n\u003cli\u003eIncludes a 1\/8 NPT sensor port for real-time fluid temperature monitoring, and optional -6AN fittings for adding an external fluid cooler.\u003c\/li\u003e\n\u003cli\u003eThe included aerodynamic air duct further reduces fluid temperatures, increasing fluid service life and reliability.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eKIT CONTENTS\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDual Mount Differential Cover Assembly\u003cul\u003e\u003cli\u003eIncludes the cover, sheet metal mounting bracket, billet aluminum mounting plate, and aerodynamic air duct. \u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eInstallation Hardware Kit\u003cul\u003e\u003cli\u003eIncludes everything you need to install this masterpiece on your E30!\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eDifferential Gasket\u003cul\u003e\u003cli\u003eChoose between a Genuine BMW paper gasket or make your own gasket with Loctite 5970.\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eOptional -6AN fittings (2) for adding an external fluid cooler. \u003c\/li\u003e\n\u003cli\u003eDifferential Cover Bushings\u003cul\u003e\u003cli\u003eChoose between Powerflex, OE MOOG, and Genuine BMW, or add your own (two E30 188mm differential cover bushings required for installation).\u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eGear Oil\u003cul\u003e\u003cli\u003eChoose between Liqui Moly, Redline, and Genuine BMW, or supply your own fluid for reassembly. \u003c\/li\u003e\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Turner Motorsports","offers":[{"title":"Default Title","offer_id":67790142964016,"sku":"4883458","price":1549.61,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/7582\/4176\/files\/1927237_x800_c3786615-19ff-4b84-a2f9-24f7f0e10fa3.jpg?v=1789507318","url":"https:\/\/es-performance.com\/products\/turner-motorsport-e30-heavy-duty-dual-mount-differential-cover","provider":"Eurosport Performance","version":"1.0","type":"link"}
