Unitec

About Unitec

Unitec is a name closely tied to practical garage and shop equipment, especially the GoJak self-loading wheel dollies and RakJak pneumatic jacks that come from Zendex Tool Corp., a Danbury, Connecticut manufacturer. Unitec products are built around one idea: moving and lifting vehicles in a tight shop should take less time and less effort.

A Background in American-Made Shop Tools

Zendex Tool Corp. has been making automotive tools in the USA since 1984. Its lineup includes GoJak, RakJak, GoJak Air and SpeedBlaster. The Unitec name appears on many of the same products and on the replacement parts that support them.

Vehicle Dollies for Moving Cars in Tight Spaces

The best-known Unitec products are the GoJak wheel dollies. A vehicle dolly lets a technician or hobbyist roll a car sideways, rotate it in place or reposition it where a drive-in approach would not fit. The GoJak design is self-loading. Stepping on the pedal lifts the tire onto the dolly, with no separate jack required. Models such as the 6520 SUV dolly are sized for heavier vehicles, and the line also includes wheel and bearing assemblies, casters and washers. Those parts let owners rebuild a worn dolly instead of replacing it.

RakJak Air Jacks

A pneumatic jack works differently from a hydraulic floor jack. RakJak units use air bags inflated from a shop compressor. They are rated at 2 tons at 105 psi and are commonly used on frame and alignment racks and for wheel, tire and suspension work. Accessories such as saddle extension adapters and replacement handle grips let you adapt the jack to different lift points.

Carts, Dollies and Shop Organization

Unitec also supports everyday shop logistics. A utility dolly and its replacement casters help move bulky or awkward loads. The GoJak storage cart is a tool cart that keeps dollies stored together and off the floor. Caster kits, including swivel TPR wheels, keep rolling equipment working smoothly.

Media Blasting

The SpeedBlaster line from the same maker covers media blasting machines for stripping rust, paint and grime from metal parts. Portable blasting units suit restoration and fabrication work where a full cabinet is impractical.

What to Consider When Shopping

• Weight rating: match dolly and jack capacity to the heaviest vehicle you will handle, including SUVs and trucks.
• Caster condition: worn wheels and bearings make dollies harder to push, so check replacement parts first.
• Air supply: air jacks need a compressor that can deliver the required pressure.
• Compatibility: confirm model numbers before ordering handles, adapters and wheel kits.
