If used with Del-a-lum Bushings
The purpose of using an offset shaft is for obtaining a proper alignment because of one of the following reasons:
- Bent frame
- Excessively lowered or raised
- Sagging frame
- Factory frame error
You can also use offset shafts for enhancing the performance of your car by changing the alignment to a more aggressive setting. Offset shafts are great for:
- Performance street alignment
- Drag racing
- Road racing
Generally speaking if we are rebuilding a stock front end and it is within the budget, we will put offset shafts in every time.
As for installation, we will install the offset shaft so the tire will be pushed out of the fender, away from the motor. The engraved words on the motor side of the shaft will read Global West. However for road racing applications it will be most likely the opposite.
Photo above: The shaft on the left is a straight shaft (standard)
The shaft on the right is offset #704. The offset shows a shift to the left. That should be towards the wheel.
Offset shafts generally give you about 1-1/4 degree change. All shafts are made out of billet steel and are supplied with hardware for the shaft, but not for the frame. The shaft is zinc coated for corrosion protection. The shafts are made to accommodate 5/8 fine thread locking nuts that are supplied in the kit.
Note: Global West tubular control arms generally never require offset shafts. We have built better alignment specifications and geometry into the control arms so offset shafts are not needed.
If you are switching over to Del-A-Lum bushings, a slotted hex nut will be supplied in the Del-a-lum kit. The slotted hex nut is used for adjusting the preload on the bushing. The shaft must be drilled using a 1/8 inch drill bit after the bushing preload is set. Why? Because just using a self locking nut provided in the kit will not hold over time, it will back off. We have found by cotter pinning the nut, maintains proper preload on the bushing.
