Q: How do I use the RPM Toe-In Gauge?
A: This is a very common question here at RPM . Although the procedure is
covered in the instructions included with the gauge, we will explain how to
use the Toe-In Gauge here along with a few descriptive photos not available
in the instructions.
Important: All toe-in measurements should be ta en with the vehicle at
static ride height. The gauge should only be used on smooth, flat surfaces.
Place the gauge on its bottom edge where there are two small feet used
to stabilize the gauge in that position. The blue nob should be facing
toward you. You should be loo ing straight down at the top edge of the
gauge. The left end of the gauge loo s li e a whale's tail (these are the
pointers) and the right end has a graduated scale and a single pointer. Each
line on the scale represents one degree of the total toe-in (1/2 degree per
side).
Please note that all references to "left" and "right" are your left and
right while loo ing at the vehicle from the front — NOT the vehicle's
left and right! Keep only light tension on the spring-loaded, blue nob.
Slide the gauge partially open. If
you are chec ing an off-road
truc , install the risers just to the
outside of the balancing feet,
under the toe-in gauge as shown
in the upper photo. With the front
of the vehicle facing you, place
the gauge under the vehicle, behind the front tires (as shown in the picture
to the right). The blue nob must be facing toward you. Choose a rib on
each tire. These ribs will be the reference ribs. Carefully place one gauge
point against the inside of the reference rib. Now slide the gauge open until
the gauge-point on the other end
touches the inside of the
reference rib on the other tire.
Tighten the blue nob while both
gauge pointers are touching the
reference ribs. Gently remove
your gauge from under the
vehicle, then reset your ride height. Place the gauge in front of the tires with
the blue nob still facing you (as shown to the left). Now, only the left gauge
pointer will be facing the tire. Place this pointer against the inside edge of
the same reference rib. On the right side, the inside of the reference rib will
be lined up with one of the lines on the graduated scale. The outside end of
the scale represents "0" degrees. Each line inwards represents one degree

of toe-in. Read the gauge at
the point where the reference
rib lines up with the line on the
scale. (If the reference rib
does not line up with any lines
on the scale, then you have
toe-out. Adjust your
turnbuc les until you get the
proper amount of Toe-In or see
"Chec ing Toe-Out" below.) If
the gauge is left loc ed down,
the vehicle can be rapidly
chec ed for toe-in changes
after a crash simply by placing
the gauge in front of the tires and, using the same reference ribs, chec ing
to see if the toe has changed.
Sedans and Other Vehicles with a Narrow Chassis
If you cannot get the toe-gauge to close far enough then there is a second
hole in your toe-gauge for the blue nob that allows the ends, or pointers, to
come closer together. Simply remove the nob from the standard position,
close the gauge until the slot reveals the second threaded hole, then
reinstall the nob. Due to tighter tread designs or the use of slic racing
tires, it may be necessary to use the inside edge of the tires for your
reference edges. Use the small risers or some thin, equal thic ness
spacers (one under each front tire) to elevate the chassis to enable you to
stand the gauge up behind the tires.
Chec ing Toe-Out (Very rarely used!)
If you prefer to run toe-out or the condition described above is prevalent,
then toe-out may be chec ed simply by starting from the front of the tires
and finishing by ta ing the reading from the bac of the tires. The only
exception being the blue nob must now face the rear of the vehicle
throughout the procedure.
