How much horsepower will 31 spline axles handle?
31 spline axles are a popular choice for high-performance applications, as they can handle significantly more horsepower than their smaller counterparts. Generally, 31 spline axles can reliably handle up to 800 horsepower, making them a suitable option for many high-powered vehicles and motorsport applications.
Understanding 31 Spline Axles
Axle splines refer to the number of teeth or grooves on the axle shaft that engage with the differential. The more splines an axle has, the stronger and more durable it is. 31 spline axles are considered a heavy-duty option, offering increased strength and torque capacity compared to 28 or 30 spline axles.
The key factors that determine the horsepower capacity of 31 spline axles include:
- Material Strength: 31 spline axles are typically made from high-strength steel alloys, providing superior tensile strength and resistance to torsional forces.
- Spline Design: The 31 spline design distributes the load more evenly across the axle shaft, reducing the risk of failure under high-torque conditions.
- Differential Compatibility: 31 spline axles are designed to work seamlessly with high-performance differentials, ensuring optimal power transfer and durability.
These factors combine to make 31 spline axles a reliable choice for applications requiring up to 800 horsepower, such as high-performance street cars, drag racing vehicles, and off-road rigs.
Factors Affecting Horsepower Capacity
While 31 spline axles can generally handle up to 800 horsepower, there are several factors that can influence the actual horsepower capacity in a specific application:
- Vehicle Weight: Heavier vehicles will place more stress on the axles, potentially reducing the maximum horsepower capacity.
- Driving Conditions: Harsh off-road environments, frequent high-speed launches, or extreme torque loads can all contribute to increased stress on the axles.
- Maintenance and Inspection: Regular inspection and proper maintenance of the axles and differential are crucial to ensuring they can safely handle the intended horsepower levels.
- Axle Modifications: Upgrades such as stronger axle shafts, upgraded bearings, or custom differential setups can further increase the horsepower capacity of 31 spline axles.
It's important to consult with a qualified automotive specialist or engineer to determine the optimal horsepower capacity for your specific vehicle and driving conditions when using 31 spline axles.
What is the maximum torque for a 31 spline axle?
Moser's tq rating is 7,000 ft/lbs per axle for the 31 splines. By that calculator, a 31-spline should be just fine.
What is the horsepower rating of a 31 spline billet axle?
Crafted from high-strength billet steel (EN1440), these precision-engineered 31 spline axles feature a 160mm spline length, allowing for adjustable overall lengths from 820.00mm to 724.00mm. Designed to handle 700 – 800 HP, these axles are ideal for high-performance applications such as drag racing and off-road builds.
How much power can a Borg-Warner diff handle?
While still a BorgWarner, the 80-series — as used in late-model IRS Falcons and Commodores — is a Dana-derived unit and there is no interchangeability with the earlier 75 or 78-series components. So how strong is a BorgWarner? Some experts we spoke to didn't rate it past 350hp, while others went as high as 500hp.
Are more splines stronger?
Generally, more splines means a larger-diameter, stronger shaft (the 14-bolt 30-spline is an exception).
What spline is a Dana 60?
35 spline
Ford Dana 60 axles mostly feature 35 spline inner axle shafts, but some are 30 spline.
How much power can 30-spline axles handle?
"This will give you a figure that represents the maximum amount of torque transmitted to both axles if you launched at your engine's torque peak and dead-hooked out of the hole. A 30-spline axle is rated at 6,200 lb-ft, a 31-spline at 7,000, a 33-spline at 8,200, a 35-spline at 9,600, and a 40-spline at 12,000.
What is a 31 spline?
Splines are the grooves on the differential end of the axle that engage the differential. They are what the diff uses to turn the axles. 31-spline axles can take more power but they won't fit a 28-spline diff. If you want to run 31s you have to upgrade to a 31-spline diff.
What is the most popular spline size?
For standard screening material, 0.140” and 0.160” spline are the most commonly used sizes. For thicker screening products, 0.125” is the most common.
Is 28 or 31 spline better?
31 spline axles which are about 30% stronger than the 28 spline axles making them a popular aftermarket upgrade for Fox, SN95, and New Edge Mustang owners.
How much horsepower can a Ford 9 inch handle?
They're good to 800 hp, if built properly.
