Evolution 4™ Spherical End Kit
 
 
Category: Axles
Rear End Components & Assemblies
Part Number(s): 58597-KIT
 
The EVOLUTION-4™ housing end system is designed to support the increased load of Pro-Stock and high powered Drag Race cars. The spherical bearing has the ability to self-align, with housing deflection, which can occur with steel housings. This system eliminates axle bearing walk-off, and reduces axle distortion aggravated by acceleration forces. The kit includes a 4130 heat treated steel housing end, (titanium ends are available at an extra charge), spherical bearing, seal and seal ring, 7075 aluminum caliper bracket/bearing retainer and fasteners. Caliper brackets are available for MW 11-3/4” diameter disc brakes and other manufacturers 11-1/2” rotors. This kit can be used on 50500 and 50800 series MW Hi-Torque ™ Axles, serial number 27482 and newer, and 50100 series axles that are specially produced for this kit . This kit allows the latest design features without adding the 12# weight penalty of our competitors two piece product.
