Driveline Tech Tips | Choose from the following...
MODULAR ALUMINUM vs. STEEL HOUSINGS
The question pops up all the time; “Why are modular aluminum rear end housings better than OEM-type stamped steel 9" housings or fabricated steel housings?” It’s certainly a valid question, given that costs typically....MORE
DISC BRAKE INSTALLATION & MAINTENANCE
One of the most important factors in the performance and subsequent service life of key disc brake components is proper alignment. If the caliper is offset in respect to the rotor position even slightly it will cause uneven pad wear —not to....MORE
AXLES & HEAT TREATING
When selecting the kind of axles to use in your race car (or street machine) there are several factors to contend with. They include determining how much of a load will be placed on the axles at launch, driveline weight considerations, and budget....MORE
OPTIMUM WHEEL SECURITY
It would seem that keeping wheels attached to race cars is of prime importance. Yet there have been many recorded instances where drive wheels have come loose; sometimes with dire consequences. When a car launches, there are....MORE
DRIVESHAFTS
There are many parameters to consider when it comes to selecting a driveshaft for your race car. These include the length of the shaft, the critical speed it will attain, the tube material type and size, the U-joint type, class requirements and budget...MORE
FULL FLOATERS VS. FLANGED AXLE
These days more and more race cars are being built with full-floater rear ends. Clearly that’s good from a safety standpoint, given that in case of an axle failure a wheel cannot come off the car. This factor alone makes a full-floating rear end a wise...MORE
AXLES
You might think that all axles are essentially the same in material, design and manufacturing ˜but you'd be quite wrong. There are actually important differences in the materials used, how they are heat treated, the machining processes employed and...MORE
BRAKE PRESSURE
One of the most important yet often misunderstood elements of any racecar is the braking system. Racers employ a disc brake system, which is made up of calipers at each wheel, brake lines, a master cylinder and a brake pedal or lever. The key...MORE
MAKING THE MOST OF TORQUE
The proverbial “800 pound gorilla” in any race car is torque. Most knowledgeable engine builders know it’s torque that wins drag races—not horsepower. And transmitting the engine’s torque to the ground is largely the responsibility of the driveline...MORE
COUPLERS & YOKES
While driveshafts provide the critical link between the engine/transmission and rear end in most vehicles with suspensions, dragsters, etc. with solid-mounted rear ends will rely on couplers. Obviously there are similarities in function...MORE
IMPORTANT DRIVELINE MAINTENANCE
With Springtime upon us, it’s a signal for racers in many parts of the country to get ready to hit their friendly local drag strip. That said, there are a number of inspections you should be doing to ensure that your race car is 100% safe from...MORE
MEASURING FOR AXLES
When it comes to ordering a pair of axles for your race car there is often a lot more to it than meets the eye. The following will give some insight into the information needed to order new axles and what to expect during the ordering process...MORE
REAR END HOUSING DYNAMICS
Back in 1687 Sir Isaac Newton published his Three Laws of Motion. Newton’s Third Law, which essentially says, “For every action there is an equal and opposite reaction,” certainly comes to bear in terms of rear end housing dynamics. We know that when...MORE
DRIVESHAFT SET-UP & MEASURING
There’s more than meets the eye when it comes to setting up and measuring for a U-joint equipped drive shaft. While the driveshaft allows for movement of the rear end there are also important operating angles and shaft length criteria that must be...MORE
SELECTING THE BEST GEAR RATIO
One of the primary reasons why the 9" Ford rear end has come to dominate drag racing is the ease with which thirdmembers with various ring & pinion gear ratios can be installed. The aftermarket has responded to this by offering a plethora of ratios...MORE
