Buying Guide for Best ford 9 inch third member 31 spline
What is a Ford 9-inch Third Member?
A Ford 9-inch Third Member is the assembly that houses the differential and gear components for the rear axle of certain Ford vehicles, as well as some other makes and models. It consists of a cast-iron or aluminum housing, with two side gears, a pinion gear, side bearings, and a center section. The center section has 31 splines that accept the axleshafts. This allows for easy installation and removal of the axleshafts.
Why Choose 31 Spline?
The 31 spline third member is best suited for vehicles with moderate to heavy modifications such as drag racing or off-roading. The larger splines provide more strength than the 28 spline version, which can be more susceptible to breakage under high torque loads. Additionally, larger splines allow for greater flexibility when it comes to axle selection as they are compatible with most aftermarket axleshafts.
What Features Should I Look For?
When buying a Ford 9-inch Third Member with 31 splines, it is important to look for high quality components that can handle higher loads during off-road use or drag racing. Look for third members made of high grade aluminum or cast iron that have been heat treated and stress relieved to ensure maximum strength and durability. Be sure to check if the third member includes all necessary parts such as side gears, bearings, seals, studs and nuts.
Which Brands Offer Quality Products?
There are many companies that offer quality Ford 9 inch third members with 31 splines such as Strange Engineering, Moser Engineering, Mark Williams Enterprises and Currie Enterprises. These well established companies offer products made of high quality materials at competitive prices.
