Late Model Asphalt Axles
Before finalizing your axle diameter choices, please consider the following:
1) Review the information under the “Choose Your Axle Diameter” tab above (or click here) to get an idea of what the different axle diameter combinations will offer in terms of performance, and what you can expect from them.
2) Consider that; the wider the thickness gap (or diameter difference) between the left & right rear axles, the more throttle turn you will have on corner exit.
3) Every Strange Oval axle is made to twist, you will gain some forward drive regardless of what axle diameter you may choose, all of which are thinner than your normal standard diameter axles….There is no wrong choice!

Gun-Drilled Torsion Bars for Sprint Cars
Strange Oval torsion bars have been winning races since 2008. We’re one of racings best kept secrets.
- Repeatable ride height without adjustment
- Holds rate for extended period of time – we’ve run them for 30+ races
- Unparalleled consistency, even after wrecks
- Seamless and smooth spline fit – leave your mallet at home
- Our manufacturing method differs from anything on the market
- Critical hardness and yield numbers are better than anything on the market
- Aircraft quality chrome vanadium steel offers superior yield strength, fatigue properties, and impact toughness
- Vertical rack heat treating controls distortion
- CNC hobbed serration splines for precise and consistent fit
- Generous transition fillet radii essential to reduction of stress risers
- Lightweight gun-drilled design
- 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
- Laser etched part number on torsion bar O.D. gives the relationship to a common solid bar’s equivalent rate
- Common solid bar number of equivalent rate also engraved onto the end of strange torsion bar for easy identification

5 Bolt Wide 5 Hub Drive Plate ADW500
Strange Oval Drive Plate Features & Benefits:
Drive Plate ADW550 (5-Lug, WIDE-5 SMART HUB only)
-
- Lightweight and high strength billet aircraft aluminum construction
-
- Pressed in steel spline insert for increased wear resistance and long spline life
-
- Flanged steel sleeve mounting hole bushings resist distortion and provide longer service life
-
- Fully CNC manufactured for consistent and accurate fit

- Critical hardness and yield numbers are better than anything on the market
- Aircraft-quality chrome vanadium steel offers superior yield strength, fatigue properties, and impact toughness
- Vertical rack heat treating controls distortion
- CNC hobbed serration splines for precise and consistent fit

5 Bolt Axle Drive Flange ADW520
Strange Oval Drive Plate Features & Benefits:
Drive Plate ADW520 (for cambered rear applications)
-
- 2 degrees of maximum misalignment
-
- Hardened components to reduce wear and increase useful life
-
- Polished articulating insert gear to improve efficiency and decrease running temperatures
- Drive flanges are plated to prevent rust
- This Strange Oval drive plate ADW520 consists of an all-steel housing and a tempered steel splined insert that articulates within the steel housing and allows for up to 2 degrees of rear camber adjustment. This drive plate is specifically for the 5-Lug, WIDE-5 hub applications. Used in conjunction with Strange Oval axles, our spline tolerances (between the axle splines and drive plate splines) are tighter and more uniform. These “closely mated” tolerances will provide better spline life of both the axles and drive plates. Strange Oval drive plates will work with virtually every 24-spline outboard axle end on the market.
