Bolt Pattern: Standard 3-Bolt (3x 5/16"-18 on 1-3/4" Bolt Circle)
The 13420 is part of the "Pro" lineup, which is a step above economy versions. It features a pin-less, spring-loaded design that allows the driver to snap the wheel onto the column without having to pull the release ring back manually.
Detailed Technical Specifications
1. SFI Certified Safety
-
SFI Spec 42.1: This hub meets the rigorous testing standards required by professional sanctioning bodies (NASCAR, NHRA, etc.), ensuring the hub will not shear or fail under extreme impact or high-torque steering loads.
-
Large Diameter Disconnect Ring: The oversized, CNC-machined release ring is easy to find and operate by "feel," even while wearing thick racing gloves or in low-visibility conditions.
2. Zero-Slop Precision
-
Tight Tolerance Splines: JOES Pro Series components are machined to exceptionally tight tolerances to eliminate the "clunk" or rotational play found in cheaper units.
This provides the driver with a direct, mechanical feel of the front tires. -
19-Tooth Spline Count: Designed to mate perfectly with JOES Pro Series steel weld-on couplers, ensuring a secure and repeatable indexing every time.
3. Lightweight "Pro" Construction
-
Ultra-Lightweight: The hub alone weighs approximately 9.6 ounces, minimizing the weight at the top of the steering column to reduce driver fatigue and improve steering response.
-
Durable Black Anodize: The hard-anodized finish protects the aluminum from the salt and sweat of the driver's hands, as well as the harsh chemicals found in a race shop.
