For strip or street, our 4-inch DOM (drawn over mandrel) aluminum shaft is ideal for high horsepower and high performance applications. Consistent strength is assured by using 6061-T6 tubing with a .120-inch wall. Plus, we maximize durability by including 1350-Series “Gold” solid U-joints.
Our customers appreciate that this driveshaft is built to stringent industry specs.
• Hydraulically straightened tubing built to a .010” total turnout at the center
• Tube yokes welded to within a .006” runout on each end
• Shafts are computer balanced to less than a ⅛ ounce/inch variance as an assembly
In most cases, we recommend this 4-inch shaft for applications up to 2,000 horsepower, or extra long shafts. For less demanding uses up to 1,200 horsepower, consider our 3.5-inch .120 wall aluminum driveshaft.

Critical Speed is calculated on each shaft to insure your Safety and Ultimate Shaft longevity. We recommend the 3.5″ shaft in most cases to 1000 Horse Power. 4″ Shafts are recommended to 2000 Horse Power. The shafts are given a brushed finish.
6061-T6 Dom tubing gives the most concentric Aluminum Driveshaft available. High strength aluminum tube yokes are mig welded with less than 10 thousands total run out. The aluminum driveshaft is balanced to less than 1/4 oz/in to assure vibration free operation. These are highly polished aluminum driveshafts, and include a 1350 trans slip yoke.
If you are buying this driveshaft for a 93-02 Camaro or Firebird, with either an M6 (manual) or 4L60E (automatic) transmission, we know the length that is normally required, provided: We base the length on whether you have a 10 bolt, 12 bolt, or 9 inch. It is recommended you measure from the back of the tailshaft to the centerline of the rear yoke, and provide us with the dimension you come up with. The rear has to be in the loaded position when you measure for the driveshaft. Brute Speed is not responsible for any added cost that may occur if you do not measure for the driveshaft, and the length ends up being wrong. Both automatic and manual transmissions use the same yoke and the driveshaft length is the same for both transmissions.
Driveshaft Measurements
If PST is supplying you with transmission slip yoke and driveshaft measure Dim X.
Note that to get these measurements the rearend needs to be in the loaded position, as in when the vehicle is being driven. DO NOT take measurements if the rear is hanging down loose.

Note: Transmission slip yokes are manufactured with various U-Joint Series. It is important to match Horsepower and Torque requirements to U-Joint Series. For aftermarket transmission applications usually a spline count and seal diameter will identify slip yoke required.
Identify Rear U-Joint
If Pinion Yoke has Placement tabs that retain the U-Joint, measure inside tabs. See Diagram D.
If Pinion Yoke does not have Placement Tabs that retain U-Joint, measure from flat of yoke inside to inside. See Diagram E.
If 4 bolt Flange is used on pinion, measure Pilot Diameter and center to center diagonally bolt hole to bolt hole. See Diagram L.
Universal Joint Size. There are hundreds of U-Joint sizes or “Series” to accomodate many different applications of power and desired longevity for your automotive, 4×4 truck or auto racing requirements, these 4 series of joints cover most needs.

How tight should I tighten my u-bolts?
1310 series and 1330 series should be tightened to 17 ft/lbs and 1350 series to 20 ft/lbs. You should never tighten the nuts on any u-bolt excessively. This will cause the cap to distort and the u-joint will fail prematurely.
