Buying Guide
Azusa jackshafts work great for go-karts and mini bikes. Users say they are easy to put on. The parts last a long time.
One user fixed an old go-kart with a new Azusa jackshaft. Another built a mini bike from scratch. They all said the parts fit well and ran smooth. A third user used the kit for a yard kart. They all liked the strong build and fair price.
-
Shaft Size: Most jackshafts are 5/8 or 3/4 inch wide. Pick the size that fits your build. A wrong size will not slide on.
-
Length: Shafts come in many lengths like 8, 10, 12, 14, and 16 inches. Long shafts fit big frames. Short shafts fit small builds.
-
Tooth Count: More teeth mean more top speed. Fewer teeth mean more push power. Pick the count that fits your ride.
-
Chain Pitch: #40 and #41 are the most common chain pitches. Match it to your chain. The wrong pitch will slip off.
-
Bore Size: The bore is the hole in the middle of the sprocket. It must match your shaft size. A loose fit can cause slips.
-
Material: Look for strong steel parts. Heat-treated steel lasts longer. Soft metal wears out fast.
-
Keyway: A keyway is a small slot cut into the shaft. It stops the sprocket from spinning loose. It keeps your drive in line.
-
Set Screws: Set screws lock the sprocket to the shaft. Two screws hold better than one. They add safe grip.
-
Threaded or Plain: Threaded shafts hold nuts on the end. Plain shafts need a collar or clip. Pick based on how you mount it.
-
Kit vs Single Part: A full kit comes with bearings and sprockets. A single part is just the shaft. Kits save time and work.
-
Price: Cheap parts may not last long. Good parts cost a bit more. Pay for parts that hold up.
-
Brand Trust: Azusa is a well-known brand. Many users trust their work. Good brands back up their parts.
-
Use Type: Go-karts need different parts than mini bikes. Yard karts use yet other sizes. Match the part to the job.
