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
- Mill scalloped to reduce weight
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.

Solid Torsion Bars for NE Dirt Modifieds
Strange Oval torsion bars have been winning races since 2008. We’re one of racings best kept secrets.
-
- Available in solid bar equivalent rates of 900, 925, 950 in 29″ length
-
- Aircraft chrome vanadium steel offers superior yield strength, fatigue properties, and impact toughness
-
- Vertical rack heat-treating controls distortion
-
- CNC hobbed serration splines insures precise and consistent fit
-
- 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
Torsion Bars should be installed so that they always twist in the same direction. The bars retain a memory of the direction they are twisting, if they are twisted in the opposite direction the spring rate will be compromised and the bar could fracture. For this reason its always a good idea to mark the torsion bars to ensure they are used in the correct corner of the car.
Rear Axle Seal
For 0.940”-1.100” O.D. Axle
With certain diameter Strange Oval axles, you’ll need to replace your inboard axle seals to accommodate the smaller axle diameters (O.D’s). Otherwise, you’ll be getting your rear end fluid into your axle tubes. We supply a very well made economical purpose-built 2 stage inboard axle seals for all of our smaller O.D. axles. We asked SEALS-IT to provide these seals to us.
SEALS-IT has been supplying NASCAR teams with various seals for over 20 years and it’s all they do.
These are 2 stage axle seals that have been designed with minimal drag.
For 1.100″-1.200″ O.D. Axle – See AGS110

5 Bolt cambered Drive Flange ADW530
Strange Oval Drive Plate Features & Benefits:
Drive Plate ADW530 (Cambered)
Strange Oval Introduces Their New 5-on-5 Cambered Drive Plate For Asphalt Late Model. They fit Howe, PCR & Vogel style 5-on-5 hubs.
It’s over 1 pound lighter than other equivalent drive plates available and allows for up to 2° of rear camber with straight splined axles.
The hub cap comes with 3 socket head cap screws.
The (optional) race-day aluminum bullet weighs 0.35 lbs. and slides over the existing flat hub cap and is secured with the same flat cap socket head screws.
The bullet cap has an indexed fit so the pre-machined lug nut lines on the cap line up exactly with the wheel studs every time.
The axles can be removed without having to remove the drive plate from the hub. Simply remove the drive plate hub cap and pull the axle straight out of the axle tube.
