Driveshaft Spacer 17mm (11/16in)

The Driveshaft Spacer 17mm (11/16in) by Steeda Autosports is an essential component for precision driveline geometry tuning on modified vehicles. This aluminum spacer addresses a critical need when upgrading suspension, lowering springs, or adjusting ride height—factors that alter the angle and positioning of the driveshaft relative to the transmission and rear differential. Built for enthusiasts running lowered setups or custom suspensions, this spacer corrects driveshaft angles to eliminate vibration, reduce wear on U-joints, and maintain smooth power delivery across the entire RPM range.

Engineered from quality aluminum construction, the 17mm spacer thickness is precisely calculated to restore proper driveline angles when factory dimensions no longer apply. When suspension geometry changes, the angle between the transmission output and differential input increases—a condition that accelerates U-joint failure and creates audible vibration at highway speeds. By shimming the driveshaft at the transmission or rear end housing, this spacer repositions the shaft into the factory working range, typically 1–3 degrees, which is the sweet spot for U-joint longevity and driveline efficiency. The compact design integrates seamlessly with existing driveshaft architecture without requiring complete reassembly or replacement.

This spacer is ideal for owners of lowered Mustangs, Camaros, Challengers, and other RWD performance vehicles where suspension drops of 1.5 inches or more are common. Installation is straightforward—unbolt the driveshaft at the transmission or differential, insert the spacer behind the existing yoke, and reassemble. Proper alignment verification via a driveline angle gauge ensures smooth operation before returning to full power. Steeda Autosports' Driveshaft Spacer 17mm is a cost-effective insurance policy against premature driveline wear, particularly when combined with other suspension modifications where factory tolerances no longer apply.
