Common safety and locking features include: spring-loaded quick-release pins and one-motion height locking for jack stands; automatic lever-locks and triple-bolt security engagement; locating lugs to grip axle tubes; anti-sink bases; and wide bases or anti-slip pads on some jacks.

Mechanisms include high-pressure hydraulic pumps and rams (porta-power kits); integrated hydraulic systems with foot-pedal control (many wheel dollies); scissor-style mechanisms operated by a crank or drill (car/RV scissor jacks); pin-and-lock or lever-lock systems for jack stands; and lever-action or ratcheting handles on some dollies.

Most tools are made from steel or high-strength/carbon steel. Common finishes include powder-coating or other rust-resistant coatings. Some heavy kits also note cast-iron components and TPU hydraulic seals, and jack stands mention electroplated cores with multi-layer powder coating.

Portability varies by type: porta-power kits typically include a portable storage case with a handle; many wheel dollies have swivel casters and carry handles or self-loading frames; scissor jacks are lightweight, foldable and trunk-friendly; jack stands often have side carry handles and compact storage profiles.

Wheel dollies commonly offer 360° swivel ball-bearing casters for multidirectional movement; twin rollers or tire cradles to secure wheels; hands-free foot-pedal, lever-action, or ratcheting controls; and self-loading frames or carry handles on some models.

Kits include a hydraulic pump and heavy-duty ram, multiple extension tubes, a variety of heads (rubber, V-shaped, chock), connecting fittings and a flat base, a long (55-inch) oil hose for extended reach, and a portable storage/carrying case.
