Product Details
A 32 inch, 1.25 inch diameter titanium live axle for go kart and outlaw kart rear ends. It runs the same 1.25 inch bearings, hubs, sprocket carriers and brake hardware you already have on the kart, so it is a straight swap for a steel or aluminum 32 inch axle on outlaw kart, jr sprint and open kart rear ends — no new carriers, no new bearing cassettes, no chassis changes.
The rear axle is the single largest piece of rotating mass on the kart, and rotating weight is not the same as static weight. Every ounce out at the axle has to be spun up out of every corner and slowed down again on entry, so the engine and the tires both feel it. Dropping to roughly 2.5 pounds of axle is one of the few changes that improves acceleration and braking at the same time without touching the engine package.
The feedback we get from customers is that the reduced rotating weight lets you cut stagger and drop 1 to 3 teeth of gear depending on the track and the kart — a lighter axle spins up quicker, so you can gear taller for corner exit and still carry the same drive off the corner. Less stagger with the same forward bite usually means a kart that is freer in the middle without getting loose on exit.
This axle starts life as a solid billet bar and is 100% machined inside and out. No tubing is used anywhere in it. Tubing is not always truly round, and any runout in the axle telegraphs straight through to the hubs, the sprocket and the brake rotor as wobble, uneven pad wear and chain slap. Machining the bore and the outside diameter in one setup keeps the wall thickness consistent and the axle straight under load.
Titanium also brings fatigue life and corrosion resistance that steel does not. It will not rust hubs and keys into place after a season of wet nights and pressure washing, which is what usually turns a routine rear end teardown into a fight.
