\"Wild<\/a><\/p>\n

Most wheel spacer returns we see have nothing to do with quality. The spacer simply did not match the machine. Two numbers decide whether a spacer bolts on or sits on the bench: the bolt pattern and the thread pitch of the studs.<\/p>\n

Our Wild Boar Wheel Spacers – 2.5″ 4\/156 3\/8×24<\/a> are sold as a pair, machined from billet aluminum, and come with the hardware you need to install them. Here is how to make sure they are the right set for your ATV or UTV.<\/p>\n

Reading 4\/156<\/h2>\n

A bolt pattern has two parts. The first number is how many studs are on the hub, in this case four. The second is the diameter of the circle those studs sit on, measured in millimeters, so 156 here. On a four-lug hub, the easy way to check is to measure center to center between two studs directly across from each other. If that measures 156mm, the pattern matches. Measuring two neighboring studs gives a different number and leads people to order the wrong part.<\/p>\n

Why 3\/8×24 matters just as much<\/h2>\n

The second spec is the stud thread. A 3\/8×24 thread is a 3\/8-inch stud with 24 threads per inch. The spacer bolts to your hub using your existing studs, so your factory lug nuts have to thread onto those studs correctly. The spacer then has its own studs that your wheel and lug nuts mount to. If your machine uses a metric stud, such as 10mm x 1.25 or 12mm x 1.5, this set is not the one. Never force a lug nut onto a stud that feels tight after a turn or two. That usually means the thread is wrong.<\/p>\n

What 2.5 inches gets you<\/h2>\n

Each spacer pushes the wheel out 2.5 inches from the hub. Do that on both sides and the track width grows by about five inches across the axle. A wider stance helps the machine feel planted on side hills and off-camber trails, and it can give bigger tires extra room so they clear suspension parts and plastics. That is a lot of added width, so think about trailer widths, narrow trails and the extra leverage on wheel bearings before you go this wide.<\/p>\n
