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

RCV Performance disconnect block-off kits are used to permanently disable the vacuum-actuated front axle disconnecting feature in vehicles with Dana 30 differentials, which are commonly found in vehicles like Jeep YJ and XJ. These kits allow for a more permanent and simpler 4x4 setup. The kits are designed to essentially bypass the vacuum system that allows the front axle to disconnect when the vehicle is in 2WD, effectively making the front axle permanently engaged. When replacing a two-piece axle with a one-piece axle set, a block-off kit is required to use a one-piece axle set. A typical block-off kits include seals and a plate to cover the vacuum-actuated disconnect mechanism. Some kits are specific to 27-spline axles, while others are designed for 30-spline axles.
