GForce Renegade Axle Shafts

GForce Renegade axle shafts offer big league strength and performance at a fair price point. They're direct replacements for your factory half-shafts and are designed for cars with everything from mild bolt-ons to those running superchargers and turbos. CNC-machined from proprietary aerospace billet alloy, Renegade axles feature upgraded spline counts on the axle bar and CV joints—providing more engagement. This allows for larger diameter bars equaling more strength, as well as more travel and increased operating angle over OEM CV joints. GForce Renegade axle shafts are a leap above entry-level, with hand-built assemblies utilizing premium materials and carefully controlled processes. Order the pair recommended for your vehicle application. Features include: * Anti-wheel hop technology—significant reduction during hard launches * Direct bolt-in fit and finish * 31-spline severe-duty CVs * Stronger one-piece CNC-machined inner and outer stubs * Powdercoated axles for corrosion protection * Black E-coat finish on inner and outer stubs to protect against harsh conditions, without impeding spline engagement

Strange C-Clip Eliminators

C-clip eliminators, which were originated by Strange Engineering, are required by drag racing rules for good reason. C-clip type axles are retained by a clip above the spline portion of the axles. When the stock axle or differential breaks, the entire axle/brake/wheel assembly can slide completely out of the housing. Strange's C-clip eliminators eliminate wheel loss and worn bearing areas. The bearings are retained and the axles are held securely in place by the C-clip eliminators, which are bolted to the stock axle housing through the existing backing plate holes.

Steeda Differential Cover Braces

When you push your Cobra to the limit in the corners, you may be applying enough force to twist the differential cover beyond its ability to flex. Repeatedly doing this causes the metal in the differential cover to separate, leaving you stranded. Steeda has come up with a solution to fix this problem. By attaching one of these Steeda differential braces, you will be adding strength and peace of mind to your differential cover. Steeda designed these cover braces with a hole to allow you to access the oil fill plug without having to remove the braces.

Spidertrax Off-Road Front Axle Stubs

Spidertrax Off-Road's all-new 1480 40 spline front axle stubs are a reinvention of their already proven 35 spline stub shafts. Manufactured from billet 300M aerospace material with an integrated positive locking design—all while achieving 50 degrees of steering—they're the next best thing in stub shaft technology… and the last stub shafts you'll ever need. These 1480 40 spline stub shafts are designed to work with 60 style U-joints and Spidertrax 40 spline Ultimate Unit Bearings. * Aerospace Quality: Spidertrax follows the strictest AMS Aerospace standards for their heat treatment, complete with double tempering, snap tempering, and cryogenic treatment procedures. Parts are sampled to ensure proper grain structure is achieved up to 0.0003 in. from the surface; that's a depth 1/10 the thickness of a human hair! In summary, you're getting the best material and the best heat treatment on the market. * Locked: Turning 40 degrees is impressive, but Spidertrax axle shafts can turn 50 degrees. Engineers achieved this by positively locking the shaft to the Ultimate Unit Bearing with a billet aluminum cap and cap screw. Keeping that stub shaft tightly secured not only helps with driveline vibration, but helps with overall strength of shaft and U-joint. * 40 Splined: Each stub shaft is 40 splined—a size that makes perfect sense, especially when running properly paired inner axle shafts. When sized with the same shaft diameter as inner shafts, stub shafts end up taking the full punishment in your front-end. The stub shaft should be "stronger" than an inner axle because unlike an inner axle, stub shafts have little room to twist, making them more prone to failure. An added bonus: with many drivers running 40 splined rear Ultimate Unit Bearings, having the same unit bearing up front makes for better serviceability and part simplicity.

GForce Outlaw Axle Shafts

High-horsepower and stock axles are fine if you're sitting in neutral and revving the engine, but foot-pounding acceleration requires Gforce Outlaw axle shafts. These direct bolt-in axles feature anti-wheel hop technology for smoother launches, powdercoating for corrosion resistance, and extremely strong CNC-machined one-piece outer and inner billet stubs. Their proprietary aerospace billet alloy shafts use large 31-spline axle bars and 31-spline severe-duty CV joints, enabling these IRS axles to support awe-inspiring performance! Outlaw CVs produce greater travel and operating angles than OE joints, helping to keep tires on the road instead of loitering in outer space. All axle assemblies are hand-built in the USA with premium materials. Order the model recommended for your application.

Auburn Gear Select-A-Loc Differentials

Auburn Gear Select-A-Loc differentials maximize your vehicle's traction with on-the-go system engage. These electronically controlled traction-enhancing differentials are selectable lockers offering the traction control of a limited-slip differential and a full-locking differential--all in one! When locker switch is off, the clutch pack activates the limited-slip mode. As torque increases, the separating forces within the differential gears increase, causing the clutch pack to be compressed, in turn providing bias torque to the highest traction wheel. When the locker switch is turned on, electronic current is sent to the electromagnetic coil which locks the axles together. Auburn Gear Select-A-Loc lockers feature a unique cone-clutch design with gearing made from aircraft-quality 9310 heat-treated billet steel for tough-as-nails strength. The lockers operate quietly without any shift fork or pins to line up to change the locker mode. With a limited-slip mode for on/off-road excitement and a true locker mode for the quarter-mile or nasty off-road terrain, Auburn Gear Select-A-Loc differentials deliver superior traction capabilities on the street, at the track, or off-road.

ARB Differential Breather Kits

ARB differential breather kits are important to vent air pressure in drivetrain assemblies, and they eliminate the shortcomings of your factory breathers—especially when driving through water crossings. ARB units are high-flow, zero backpressure, zero vacuum breather systems. Each features a high-flow air filter within a central manifold that will allow up to four drivetrain assemblies to be vented to one central location--ideally somewhere on the vehicle that will be above the water level at all times. ARB differential breather kits are intended to replace your factory breathers and contain enough fittings and tubing to connect at least two drivetrain assemblies. Additional features and benefits include: * Axle breather manifold is machined from billet aluminum and anodized, making it lightweight and resistant to the elements * The manifolds have four axle breather ports, allowing for 1-4 breather lines to be connected * Very compact design, allowing them to be installed in virtually any location * The kits come with self-tapping screws, but the manifold mounting holes are large enough to allow mounting using an M6 (1/4 in.) bolt or stud, which is the common size in most vehicle engine bays * The air filters are the ARB compressor air filters, which are splash-resistant with washable high-flow sintered bronze filter cartridges * 8mm polyethylene tubing is flexible, oil-resistant, water-resistant, and heat-resistant * 8mm tubing has been selected over the standard 6mm tubing to improve the airflow and reduce the chance of oil blockages in long breather lines * 8mm push-in fittings make installation simple and fast * Kits include anodized aluminum manifold with 5 ports (breather lines and air filter) and 2 mounting holes, air filter assembly, fittings, plugs, polyethylene tubing, screws, and cable ties
