Strange Engineering Differential Housing Support

Strange Engineering Differential Housing Support: Keeping Your Rear End Intact Under Pressure

When horsepower levels climb and launches get aggressive, the weakest link in a performance drivetrain is often the differential housing itself. Housing flex leads to increased side bearing clearance, ring gear deflection, and ultimately gear failure — exactly the kind of problem that Strange Engineering has spent decades engineering solutions for. Their Differential Housing Support products are a direct answer to this real-world problem, combining structural engineering with race-proven design to keep your rear end rigid when it matters most.

The "Ultimate Support" Aluminum Cover Series

Strange Engineering's flagship housing support products fall under their LPW Ultimate Support Cover line — thick aluminum castings designed to do far more than simply seal your differential. These covers feature a thick aluminum casting that provides structural support to the housing and improves gear life by reducing housing flex. This is a critical distinction: while a standard stamped steel cover is little more than a lid, Strange's Ultimate Support covers act as a structural reinforcement brace for the entire rear end assembly.

What truly sets these covers apart is their integrated jack screw system. Jack screws preload the main caps and raise the threshold where deflection would cause breakage. By reinforcing the rear housing from case distortion under load, they prevent increased side bearing clearance and ring gear deflection, while two adjustable Grade 8 bolts support and stop bearing main caps from moving or breaking.

Brace-Ready Design and Broad Fitment

Strange Engineering also engineers their housing support covers with an eye toward modularity. A back brace provision allows the use of an optional back brace kit, which drastically reduces axle tube flex — a key upgrade for vehicles running serious power. The covers also feature built-in fill and drain plugs, simplifying fluid changes and making cover removal unnecessary.

The Ultimate Support Cover line spans a wide range of popular performance axle platforms, including the GM 8.2" and 8.5" 10-bolt, GM 12-bolt truck, and the Dana 60 / Strange S60 — the latter being especially popular in high-horsepower and Pro Street builds. This broad fitment reflects Strange Engineering's standing as the most recognized name in the aftermarket industry for rear-end components, with Strange Ford 9-inch housings relied on by more racers than all other manufacturers combined.

Built by a Brand That Understands Rear Ends

Strange Engineering was founded inside a two-car garage in the late 1950s and has grown into an industry leader for driveline and suspension products. For over 50 years, Strange Engineering has been synonymous with drag racing excellence, renowned among racers and crew chiefs for supplying premier driveline and suspension components. That racing DNA is baked into every housing support cover they produce — these are not catalog parts designed to a price point, but components engineered by people who understand what happens to a differential housing when a 900-horsepower car hooks hard off the line.

• Thick aluminum casting for structural rigidity and reduced housing flex
• Adjustable Grade 8 jack screws to preload main caps and prevent breakage
• Back brace provision on select covers for optional axle tube brace kits
• Built-in fill and drain plugs for convenient fluid maintenance
• Fitment for GM 10-bolt, GM 12-bolt, Dana 60, and Strange S60 axles

Whether you're building a street/strip muscle car or an all-out drag racer, Strange Engineering's differential housing support covers are a smart structural upgrade that protects your investment in ring and pinion gears, bearings, and carrier components.
