Front hub CRG KZ 40x80 R2.0 All. Full gold.

Full description of the product (H1: Front hub KZ CRG 40x80 mm R2.0 Gold Aluminum - Complete)

The front hub CRG 40x80 mm (R2.0 range) in anodized finish Gold is a part of the original manufacturer (Original CRG Share), specifically developed to meet the extreme mechanical stresses of the Queen category chassis Kz (gearbox).

With his inside diameter of 40 mm (adapted to the large diameter rockets specific to KZ) and its 80 mm length, This hub of the R2.0 series offers a perfect seat for your front train. In kz, the power of the front braking and the motor torque require absolute rigidity. This CNC machined aeronautical quality aluminum hub enciesive these lateral forces without flexing, ensuring a surgical directional precision in full support. Its superb gold anodized finish protects the aluminum from corrosion while bringing the official "racing" look of the group's high-end chassis.

Specificities of the "complete" model:

The hub is delivered factory assembled and ready for the track:

• The hub body 40x80 mm aluminum anodized gold (R2.0 series).

• 2 high precision rocket bearings 40 mm already fitted.

• The internal spacer calibrated for perfect alignment of bearings.

• The 3 wheel studs high strength to fix your rim.

• The clamping ring and locking screw to index your way settings.

👨🔧 3. Tip in Michel (the corner of the expert)

* "Hi the artists of the gearbox! The hub R2.0 Gold in 40x80 is the great room, but be careful at mounting. In KZ, the front brake discs heat a lot and transmit all their temperature to the rocket and bearings of 40 mm.

My obligatory trick: never climb these big dry hubs. Clean nickel the rocket axis with brake degreaser and apply a very fine copper grease or high temperature white grease. If you go up that dry, with the calories of braking, the hub aluminum and the steel of the rocket will spray by electrolysis. To get it out at the booth, you will have to tap on it and you risk sailing this beautiful piece !

And for cleaning, avoid too acidic products that tarnish gold anodizing. A cloth shot with brake cleaner or WD40 and it shines like the first day! "*

❓ 5. FAQ SEO (Frequently Asked Questions)

Q: Does this 40 mm hub adjust to a standard category kart (Rotax Max, x30) ?

A: Not. The category karts without box (single Speed) generally use 17 mm or 25 mm diameter rockets. This 40 mm hub is exclusively reserved for the massive rockets of the KZ (box) chassis, equipped with steering wheel front brakes.

Q: Why choose the 80 mm length rather than a longer or shorter hub ?

A: The length of 80 mm is the most versatile standard. A shorter hub (ex: 65 mm) gives more mechanical flexibility to the rocket and helps release the front train if the track is very eager. A longer hub (ex: 95 mm) increases the stiffness to the extreme to give immediate grip on a slippery or cold track. The 80 mm offers the perfect compromise for all conditions.

Q: Are the internal 40 mm bearings replaceable ?

A: Yes, quite. Although this hub is delivered complete with its factory-mounted original bearings, the 40 mm bearings remain consumables. You will be able to replace them in the future using a conventional rolling extractor, without the need to replace the gold aluminum hub body.
