Build your kit
Take control of your vehicle's alignment at home with a kit tailored to your needs. Choose a wheel clamp, a gauge, and turn plates, then bundle them together and save compared to buying individually.
Choose from the standard Wheel (Rim) Clamp, the 6-Point Clamp with tire tread grip extensions, or the Tire Clamp for larger wheels. Available in 1, 2, or 4 packs.
Pick the Camber/Caster Gauge for basic readings, the Digital Camber/Caster Gauge for an LCD readout, or the 3-in-1 Camber, Caster & KPI Gauge for full diagnostics.
Select the Drive On low-profile plates for home garages or the Pit Rack plates for lifted vehicles. Both feature brass-finish dials and 4-ton capacity.
Add support tools like the Steering Wheel Holder, Brake Pedal Depressor, or Toe Alignment Plates to complete your setup.
Every build starts from the same foundation: turn plates, a wheel clamp, and the camber, caster and KPI gauge. From there the builder is yours: add ramps and level platforms, a second clamp and gauge, toe plates, or the steering and brake holds. Pick the tools that fit your garage, and the kit discount grows with every one you add.
Five component groups make up the builder. Pick one to see what it does and when to add it.
The clamp is the mount everything else hangs off. Spring-loaded pins seat on the rim lip so the body sits square to the wheel without touching the face. It fits 11 to 25 inch rims and it is where every build starts.
The gauge magnet-mounts to the clamp face and stays there for the whole set of angles. Camber and KPI each read from their own vial. Caster comes from a sweep, turning the wheel through the arc on the turn plates and reading the change across it. One mount, three angles, nothing swapped in between.
Turn plates go under the front wheels and lift them 0.8 inch, so the wheel can swing through the caster sweep instead of scrubbing on concrete. That lift also puts the nose of the car higher than the tail. Ramps and level platforms answer it: a ramp for every wheel and platforms for the rears, bringing all four corners up to one height.
Camber, caster and KPI live at the wheel. Toe lives between the wheels. The plates sit against the sidewalls, tapes run front and rear under tension, and the string picks up the line the car actually tracks. One string box covers toe, thrust and steer-ahead together.
A steering wheel creeps the moment you let go of it, and a car that rolls moves what you just set. The digital steering level sets the wheel flat, the holder locks it there, and the brake pedal holder keeps the car from creeping while you move corner to corner. These three are what turn a two-person job into a one-person job.
The same five steps whatever you build. Steps four and five only apply when you added those tools.
Roll up the ramps and onto the turn plates, then let the car settle on its own suspension. Pull the turn plate pins once it has settled, not before. Rolling on is the method to use: dropping the car from a lift pushes the wheels outward under load and binds the pins.
With ramps and level platforms in your build
Seat the clamp pins against the rim lip and snug it down, then set the gauge onto the clamp face. The magnet does the holding. Check the clamp is sitting square to the wheel before you read anything off it.
Every build
Camber and KPI read from their own vials on the same mount. Caster is different: sweep the wheel through 20 degrees on the turn plate and read the change across the sweep. Nothing gets unbolted between the three.
Every build
Toe plates against the sidewalls, tapes front and rear pulled to tension, string through the loops. Square the box to the car and one setup gives you toe, thrust and steer-ahead together.
With toe plates in your build
Level the steering wheel, lock it with the holder, and set the brake pedal holder. Everything stays where you put it while you walk to the other corner.
With the support tools in your buildThe four additions builders reach for most. Each one removes a specific piece of work you would otherwise do by hand.
On turn plates alone the front wheels sit 0.8 inch up while the rears sit on the floor, so the car sits nose high unless you plank the rear yourself. Add ASRP004 and every corner comes up to one height: a ramp for every wheel, level platforms for the rears, and the car sits flat.
One clamp and one gauge means doing a side, unbolting everything, and walking it around the car to do the other. Double them in the builder and you mount both fronts once, sweep caster side to side, and compare left against right without touching a setting in between.
Camber, caster and KPI live at the wheel. Toe lives between the wheels, and the ASTPSETX toe plates reach it. Plates against the sidewalls, tapes front and rear, string through the loops. One setup covers all three, with no extra hardware.
A steering wheel creeps the moment you let go. Add the digital steering level, the wheel holder and the brake pedal holder: level the wheel, lock it, hold the brakes. Everything stays where you set it while you move corner to corner.
