Kera Axles are available in Short Track Gun-Drilled, NASCAR Style and Carbon Fiber. Sizes range from 1.125in. to 1.215in. width and 25in to 41in. in length. To be able to run up front you need the axles designed and manufactured by the team at Kera Axle.

• Promotes maximum traction by offering various diameter/length combinations and by producing simultaneous "Wrap-Up" of axles during acceleration and deceleration.

• Maximum durability is achieved through usage of same proprietary material used in the NASCAR style axles.

• Available for most dirt and asphalt applications.

• Provides a quicker and smoother acceleration rate.

• Ability to tune chassis with various axle diameters.

•   Gun drilled for lightweight characteristics.

• Shot peened after heat treatment.

Strange Oval KERA Axles have been, and continue to be utilized by many of the top teams in the NASCAR Sprint Cup, Nationwide & Truck series since 2008.

Ultra high strength low alloy steel offers outstanding yield and tensile strengths, fatigue properties, and high toughness Vertical rack heat treating controls distortion CNC hobbed splines tightly controls tolerances for even torque transfer and consistent misalignment angle of drive flanges

Generous transition fillet radii essential to reduction of stress risers Additional attention directed to non-aggressive machining to impart a minimum amount of residual tensile stress

Shot peening provides increased torsional and bending fatigue life with the application of residual compressive stress

Isotropic superfinishing reduces spline wear, lowers operating temperature, and minimizes micro stress risers

While left and right side axles are different lengths they are normally the same diameter; this inherently gives the right side axle a lower spring rate. This means the left side axle does not “wrap-up” as much as the right side and the car has a tendency to steer right on initial acceleration because the left rear tire sees the power first. By using a smaller diameter left hand axle with the “KERA concept” you can equalize this torque steer reaction both under acceleration or deceleration.

This Equal-Response-Reaction can be further used to specifically tune the chassis to turn left by reducing the left side axle diameter further from the standard KERA diameter split between the left and right side axles. In effect, the Kleban Equal Response Axles (KERA) can be used as a precise tuning device like that of tire stagger without having any effect on existing cross weight, spring rates, anti-roll bar, ride height or tire pressure.

R = 1.200"R = 1.165"1.130"
    BELOW - Use existing RR (1.200" diameter) when you really want to loosen the car up on exit. This would act like you added 1" to 1.5" of tire stagger BUT without adding any. Take RR from option 1 above and move it to the LROption 3
      LR = 1.130" (Normally used on RR)
    RR = Existing 1.200" 
 Here's what you can expect from the Options listed:     
1Forward BiteUsing the smallest axle diameter allowable (based on HP) you will encourage both left & right axles to "wrap-up" at virtually the same rate. Maximizing axle wrap will make it more difficult for the tire to break traction on acceleration, whether it's on corner exit or on restarts. You don't have to worry about the axle breaking from twisting, the material & design is meant to twist all day without any damaging effect on the axle.                              Best Suited Track Type:   Dry-Slick                         
2Most Throttle Turn        (a bit Loose On Exit)This option is our maximum recommended offset between the left & right side axle diameters to allow for "on throttle" turn like that of adding tire stagger. The greater the diameter split between the left & right axles, the more "loose" the effect is "on throttle". Forward bite is slightly reduced to a degree (from Option #1), but the axle diameters here still remain much thinner than standard axles sold which will allow for axle "wrap-up" and increased forward bite over any standard diameter axles.                                                                                                    Best Suited Track Type:   Heavy or tacky 
3Some Forward Bite & Throttle TurnHere we utilize axle diameters that will provide a bit of both Options #1 & #2 (Forward Bite & Throttle Turn), using smaller diameters overall with a slight split between left & right side axle diameters. This options best captures a bit of axle wrap (Forward Bite) with the thinner overall axle diameters & throttle turn (the tire stagger effect) that comes with different left-to-right axle diameters. It is our most commonly used axle combination.         Best Suited Track Type:   Starts heavy or tacky and gets more dry-slick through the night

Products typically ship out between the same day and 1-3 days. Depending on the time/day ordered and the product type. Some products are made to order to spec and will ship once built. Feel free to call us at 704-871-0721 if you have any questions about shipping. Also call us if you are ordering large items like race car bodies as those are hard for the freight system to calculate sometimes and it will overestimate. Thank you.
