3.5" Chromoly Drive Shaft (1480 Ujoint)

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.

These driveshafts use 4130 heat treated chromoly welded to true 4130 yokes. Mark Williams weld yokes are produced in-house to exacting tolerances to provide the proper press fit in the chromoly tube. These driveshafts are carefully joined using an automated cold wire TIG process.

This chromoly driveshaft features a 1480 series precision u-joint, which is then installed along with the forged 4340 heat treated transmission yoke (sold separately). 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.

Each driveshaft is custom built to length an specifications. These driveshafts are precision built, assembled, and balanced using in house machined components. 

Special assembly fixtures guarantee proper weld yoke phasing during assembly. Every shaft is electronically high speed balanced considering your maximum RPM requirements, with the transmission yoke to ensure vibration-free operation.
