Supertracker STR420 Compact – 8 Sensor CCD Wheel Alignment System for Independent Garages

From £6,799 + VAT (Was £7,400)

Supertracker's latest tablet controlled, space-saving CCD wheel alignment system. The same user-friendly and intuitive operating system as the cabinet-based STR420RW, now supplied with a Windows tablet in a rugged magnetic case — offering convenience right where you need it in your workshop.

The STR420 Compact wheel alignment machine is housed on a compact, sleek and highly manoeuvrable storage unit which significantly reduces the required floor space and allows 4 wheel alignment to be carried out anywhere in the workshop, without being anchored to one bay.

The STR420 delivers impressive speed, completing setup and full wheel alignment readings in as little as 59 seconds. With an additional two rear sensors on top of the standard 6, the STR420 enables measurement of Rear Set Back and factors track width when assessing Rear Toe — delivering a more comprehensive alignment picture than a standard 6 sensor wheel aligner.

Hang-On Measuring Heads – No Risk of Rim Damage

The Supertracker hang-on system is a tried and tested method of attaching measuring heads to wheels on any wheel alignment machine. With no clamping or metal contact, the rim buttons cause no damage to alloy or painted wheels. They are quick and straightforward to fit and remove, and the measuring heads and hangers store neatly together as a single unit — all saving valuable workshop time.

The updated design now includes a sliding T-slot mounting system for quick positioning and easy removal of the hanger system on the side of the Compact trolley.

Wheel Alignment Software – Easy to Use, Comprehensive Vehicle Coverage

The user-friendly wheel alignment software is designed to make operation easy to navigate and information easy to read. It also features adjustment help screens to assist technicians with a variety of vehicle adjustments — ideal for independent garages handling a wide range of makes and models.

The system includes a comprehensive vehicle database with customer history recall, which can be updated annually to keep pace with new models. The STR420 Compact also has network capabilities, enabling connection to an office or network printer with a choice of printouts. It can even receive remote access support directly from the Supertracker factory — minimising downtime and keeping your workshop productive.

The STR420 Compact 4 wheel alignment system is supplied as standard with everything you need, including:

STR420 Compact vs STR130 Compact – Which Wheel Aligner Is Right for Your Workshop?

The STR420 also completes full alignment readings in as little as 59 seconds.
