Rear End Plug Kit Hex

The Rear End Plug Kit Hex from King Racing Products is a precision-engineered solution for maintaining differential integrity during seasonal storage, maintenance, or when running winter setups. Designed for drag racers, street-strip enthusiasts, and serious gearheads who swap rear ends or need to seal axle tubes, this kit prevents fluid contamination, debris ingress, and oxidation when a differential is not in active use. Whether you're storing a rear end for winter or prepping a dedicated drag racing differential, the hex head plugs deliver a secure, reusable seal without improvisation.

This kit features aluminum construction finished in durable black anodize, offering both corrosion resistance and a clean appearance that matches modern performance builds. The O-ring seal design ensures a tight, leak-proof fit that won't weep or allow contaminants past the plug surface—critical when a bare differential sits on the shelf for months. The hex head design allows straightforward installation and removal using standard wrenches or sockets, eliminating the need for specialized tools. Black anodized aluminum resists weathering and won't corrode even in humid storage conditions, maintaining structural integrity and seal reliability across multiple seasons of use.

This plug kit is ideal for DMI rear ends, winter storage applications, and dedicated drag racing differentials where protection against moisture and dirt is essential during downtime. The compact, lightweight design (0.19 lbs) makes it practical for transport between locations or safe storage alongside your spare diff. Installation is straightforward: remove old drain or filler plugs, clean the mounting surface, and thread the sealed hex plugs hand-tight, then final-torque with a wrench. Compatibility spans most rear end housings that accept standard-sized plugs; verify your rear end's port thread size before ordering to ensure proper fit and seal performance.
