Features
Mobile Wheel Alignment Machine for 2-Post and Scissor Lifts
Mobile 3D wheel alignment machine moves between 2-post and scissor lifts, reducing vehicle transfer time. Dual-camera system mounts on a rolling stand and adjusts height manually for different vehicles. Enables alignments on existing service lifts without dedicating a fixed bay.
No Calibration Installation Saves Setup Time
Requires no calibration during installation or use. Self-referencing 3D cameras allow immediate operation after setup and maintain accuracy when moved between bays. Cuts setup time from hours to under one hour compared to traditional alignment machines.
Unlimited Vehicle Memory with Yearly Database Updates
The system stores unlimited vehicle specifications in its memory, pulling OEM alignment specs for US, European, and Asian makes. You won't hit storage limits or need to delete old entries to make room for new models. The database updates arrive yearly at no charge, adding the latest model-year vehicles and revised specs from manufacturers. Each update arrives as a simple file transfer via the included USB drive or over Wi-Fi, taking 10-15 minutes to install. The smartphone sync feature lets you pull up a vehicle's spec sheet on your phone while you're under the car adjusting camber bolts, which beats walking back and forth to the main display.
Complete Digital Wheel Alignment Machine Hardware Package
You get the full working system in one shipment: tablet with pre-loaded software, 30-inch primary display, thermal printer for customer reports, wireless mouse and keyboard, Wi-Fi adapter, and USB drive for data transfer. The 2-camera configuration handles all four-wheel alignment measurements, tracking both front and rear axles simultaneously. Power requirements are simple—any standard 100-240V outlet on a 1-phase circuit handles the entire system, so you won't need dedicated electrical work. The printer spits out alignment reports in under 30 seconds, with before-and-after readings that customers can read without squinting at a screen.
Android and iOS Software with Smartphone Display Mirroring
The system runs on Android and iOS platforms, which means software updates arrive through the same process you use for phone apps. You won't need a Windows laptop or deal with operating system compatibility issues. The synchronous display feature mirrors the main screen to any smartphone or tablet on your Wi-Fi network, letting customers watch alignment readings change in real time as you make adjustments. This transparency cuts down on "what are you actually doing back there" questions and helps justify alignment costs when customers see their toe reading go from 0.24° out to 0.02° after adjustment.
Wide Operating Range for Passenger Cars and Light Trucks
The KT-AV651 operates in temperatures from 41 F to 104 F (5 C to 40 C), handling most shop environments without climate control. It measures wheelbases from 62.9" to 82.7" (1.6-2.1 m) and track widths from 70.9" to 177.2" (1.8-4.5 m), covering compact cars through full-size trucks. Tire diameter range spans 9.8" to 31.5" (250-800 mm), which includes most passenger and light truck tires but stops short of medium-duty applications. The 2-camera design captures all necessary angles for toe, camber, and caster readings, though you won't get the multi-angle verification that 4-camera systems provide.

Applications
The KT-AV651 targets shops that need alignment capability without dedicating permanent floor space to a fixed rack. Suitable for shops seeking a wheel alignment machine for sale that works on existing 2-post or scissor lifts and expands service capacity without adding lift bays. Independent repair shops running 2-post lifts gain alignment services without adding a third lift bay. Tire shops can align vehicles on the same lift used for mounting and balancing, cutting transfer time between service bays. The mobile design also fits shops with scissor lifts, where traditional alignment racks won't work due to the lift's footprint.
Vehicle coverage includes passenger cars, crossovers, SUVs, and light trucks up to 1-ton capacity, as long as they fall within the wheelbase and track width ranges. The system handles front-wheel drive, rear-wheel drive, and all-wheel drive configurations. You'll measure and adjust toe, camber, and caster on the front axle, plus toe and camber on the rear for four-wheel alignments. Shops focusing on compact imports or domestic passenger cars will find the measurement ranges more than adequate, while those working on lifted trucks or commercial vans will hit the upper limits of the track width specification.

Installation
The KT-AV651 needs a standard 100-240V outlet on a 1-phase circuit, which you'll find in any shop with basic electrical service. There's no special circuit requirement, no 3-phase power, and no need to run new wiring. The system works in ambient temperatures from 41 F to 104 F (5 C to 40 C), handling unheated shops in mild climates or air-conditioned facilities in hot regions. You'll need clear floor space to position the camera stand between your lift posts, with enough room to roll the unit out of the way when not in use.
Setup takes under an hour once the crate is open. You'll bolt the cameras to their mounting bar, connect the power cable, and link the tablet to the main display. The Wi-Fi adapter connects your devices, and the printer plugs into a USB port on the main unit. There's no floor mounting, no overhead projector alignment, and no initial calibration procedure. The instruction manual walks through the connection sequence with photos at each step.

Frequently Asked Questions
How do you use a wheel alignment machine like the KT-AV651?
Position the vehicle on your 2-post or scissor lift, roll the camera stand into place between the lift posts, attach wheel sensors to all four wheels, and follow the on-screen prompts on the tablet or 30-inch display. The system guides you through vehicle selection, rolling the wheels to establish initial readings, and making adjustments. The entire process takes 15-20 minutes for an experienced technician on a typical passenger car alignment.
Will this 2-post wheel alignment machine work with my current lifts?
The KT-AV651 works with any 2-post lift or scissor lift that has clear floor space between the posts for the camera stand. You'll need at least 36 inches (915 mm) of clearance width for the rolling camera bar, and the vehicle must sit within the 62.9-82.7 inch wheelbase range and 70.9-177.2 inch track width range. The system works regardless of your lift's weight capacity or manufacturer, as long as you have the physical space to position the cameras.
What's included when you buy this four-wheel alignment machine?
The complete package includes the dual-camera 3D alignment system with rolling stand, a tablet with pre-loaded software, 30-inch primary display monitor, thermal printer for customer reports, wireless mouse and keyboard, Wi-Fi adapter, USB drive, all necessary cables, wheel sensors for four wheels, and the instruction manual. You don't need to purchase a separate computer, monitor, or printer to start running alignments.
How much does a 4-wheel alignment machine like this cost to operate?
The KT-AV651 has no ongoing calibration costs since it requires zero calibration during or after installation. You'll pay for yearly database updates (included free for at least the first year), printer paper for customer reports (thermal paper rolls cost approximately $15-25 per roll and print 200-300 reports), and standard shop electricity at about 0.5 kWh per alignment. There are no proprietary sensors to replace on a schedule, no Windows license fees, and no monthly software subscriptions.
Does this digital wheel alignment machine work with ADAS calibration systems?
The KT-AV651 does not include ADAS (Advanced Driver Assistance Systems) calibration capability. It performs traditional wheel alignment measurements for toe, camber, and caster on front and rear axles. If you need to calibrate forward-facing cameras, radar systems, or lane-keeping sensors after an alignment, you'll need a separate ADAS calibration system. The alignment readings themselves are digital and displayed on the 30-inch monitor and tablet, but the system focuses solely on wheel positioning measurements.
What measurement accuracy can I expect from this portable wheel alignment machine?
Katool does not publish specific accuracy tolerances for toe, camber, or caster measurements in the product documentation. The dual-camera 3D system uses the same basic measurement technology as fixed-bay systems at higher price points, calculating wheel angles from camera-captured images of wheel-mounted targets. Most 3D systems in this category measure within 0.02-0.05 degrees for toe and camber, and 0.05-0.10 degrees for caster, though you should verify these specifications directly with Katool before purchase if your shop requires documented accuracy standards.
Can this mobile wheel alignment machine handle lifted trucks or commercial vehicles?
The system's track width specification maxes out at 177.2 inches (4.5 m), which accommodates full-size pickup trucks and vans in stock configuration. Lifted trucks with aftermarket suspension often exceed the maximum track width, and the 31.5-inch maximum tire diameter rules out larger truck tires. The 82.7-inch maximum wheelbase fits most passenger vehicles and light trucks, but medium-duty commercial vehicles with extended wheelbases will fall outside the measurement range. For stock passenger cars through full-size pickups, the system covers the range completely.
How often do I need to update the vehicle database, and what does it cost?
The KT-AV651 includes free yearly database updates for the first year, covering new model-year vehicles and revised OEM specifications. Updates arrive as downloadable files that transfer to the system via the included USB drive or over Wi-Fi, with installation taking 10-15 minutes. After the first year, Katool may charge for subsequent database updates, though the pricing structure is not published in current product documentation. The system stores unlimited vehicle specifications once you install them, so older vehicles remain in the database permanently without requiring repeated downloads.
