When it comes to a bulletproof driveline, the MW chromoly driveshaft is the strongest. A chromoly shaft is 75% stronger than commonly used 1020 DOM material. To ensure the quality of the material, the 3" x .083" 4130 heat treated tubing used is manufactured to MW's stringent specifications. The perfect companion to MW's chromoly tubing is the MW produced, 4130 forged weld yokes  used in each assembly. These weld yokes are produced in-house to exacting tolerances to provide the proper press fit in the chromoly tube. Precise alignment, of "phasing", of the weld yokes is critical to smooth operation. MW weld yokes and chromoly tubing are assembled using a specially built alignment / assembly fixture, then carefully joined using an automated cold wire TIG process. MW's exclusive 1350 series precision u-joints are then installed along with the forged 4340 heat treated transmission yoke (sold separately). Each assembly is high-speed electronically spun and balanced at a RPM that represents operating speed, to G30 industry tolerances. The finished product is a driveline capable of handling today's most powerful vehicles. Prices are less transmission yoke. All 4130 chromoly driveshafts meet SFI spec 43.1.
