STR420 8 Sensor CCD Aligner
Supertracker STR420RW – 8 Sensor CCD Wheel Alignment System for Independent Garages
From £7,499 + VAT (Was £8,500)
The Supertracker STR420RW 8 sensor wheel alignment system covers all aspects of adjustability within the modern vehicle chassis. The fast setup speed enables you to carry out a high volume of alignments per day — completing full readings in as little as 59 seconds.
The STR420RW has two additional sensors over the STR130RW, positioned across the rear, providing measurement for Rear Set Back as well as taking into account track width when measuring Rear Toe — delivering a more comprehensive and accurate wheel alignment result.
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 as a single unit — all saving valuable workshop time.
The robust design and solid-state electronics ensure exceptional durability and reliable performance, even in demanding workshop environments. Inbuilt control panels on each head eliminate the need to return to the console during each stage of the wheel alignment process.
The STR420RW can also be supplied with 3-Point clamps, either in addition to or as an alternative to the hangers, allowing for precise wheel alignment on lowered vehicles.
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. The system includes an extensive vehicle database with customer history recall, updated annually to keep pace with new models.
The STR420RW also has network capabilities, enabling connection to an office or network printer with a choice of graphic or tabular colour printouts. It can even receive remote access support directly from the Supertracker factory. Additional monitors can also be installed in waiting areas or receptions for customers to view their alignment results.

STR420RW Wheel Aligner – Frequently Asked Questions
What is the Supertracker STR420RW?
The STR420RW is an 8 sensor CCD wheel alignment system from Supertracker, designed for independent garages and workshops that need comprehensive alignment capability and high throughput. It completes full alignment readings in as little as 59 seconds and includes Rear Set Back measurement.
What is the difference between the STR420RW and the STR130RW?
The STR420RW has 8 sensors compared to the STR130RW’s 6. The two additional rear sensors enable measurement of Rear Set Back and factor track width when assessing Rear Toe, delivering a more comprehensive wheel alignment result. The STR420RW also completes full readings in as little as 59 seconds.
What is the difference between the STR420RW and the STR420 Compact?
Both systems use the same 8 sensor technology. The STR420RW is a cabinet-based system with a full PC workstation, monitor and printer included as standard. The STR420 Compact replaces the cabinet with a compact, manoeuvrable trolley and a Windows tablet — ideal where workshop floor space is limited.
Can I see the STR420RW in action?
Yes — watch the STR420RW video on YouTube to see the system demonstrated.
What is Rear Set Back measurement?
Rear Set Back measures whether the rear axle is square to the vehicle centreline. It is an important measurement for identifying chassis damage or suspension issues that a standard 6 sensor wheel aligner would not detect.
Does the hang-on system damage alloy wheels?
No. The Supertracker hang-on system uses rim buttons with no clamping or metal contact, so there is no risk of damage to alloy or painted wheels — making it ideal for prestige and performance vehicles.
Can the STR420RW be used with lowered vehicles?
Yes. The STR420RW can be supplied with 3-Point clamps, either in addition to or as an alternative to the standard hangers, allowing for precise wheel alignment on lowered vehicles.
Can the vehicle database be updated?
Yes. The extensive vehicle database can be updated annually to ensure coverage of the latest vehicles, keeping your wheel alignment system current.
What lift types is the STR420RW compatible with?
