Andy's Auto Sport is the ultimate shopping destination for your Saab 99 differential needs!


WHY TO BUY?
An aftermarket differential can substantially improve your vehicle's performance, ensuring that your drive wheels get the proper amount of traction at any given time. This is especially important if you depend on your vehicle to handle consistently through turns without excessive wheel slip, or in racing situations such as circuit, drag, or off-road racing. The bottom line is, your vehicle isn't truly high-performance unless it's rockin' a limited-slip differential.
DID YOU KNOW?
Most, if not all, exotic sports cars and heavy-duty trucks employ some sort of limited-slip differential to improve traction during less-than-ideal conditions, but the same technology is also available to those of us with vehicles that weren't equipped with a limited-slip differential (also known as an LSD) from the factory. Various types of locking differentials are available, including clutch-type and Torsen-type, as well as air-actuated "locker" differentials, which give the driver complete control over when the diff is locked to the axles.
FAQ's
Q: What is a differential? Why buy one?
A: The differential is the device inside of your drive axle that transfers power from the driveshaft to the wheels; however it also lets the wheels spin independently at different speeds so that your vehicle can turn without issues. Most stock vehicles feature open differentials which work fine for day to day driving but are not ideal for maximum traction. Limited slip differentials and full locking differentials are also available if you are looking to boost traction for racing or off road situations. Limited slip differentials minimize the amount of slippage between the two wheels so that power is applied to both wheels at near equal levels which keeps your vehicle moving forward even if one wheel slips a little. Locking differentials physically lock up the internal components of the differential so that both wheels have to spin at the same speed, meaning that both drive wheels always get the same amount of power, thus maximizing vehicle traction. Both of these types of differentials are a significant upgrade over a stock differential however they can be tricky to use for street driving so be sure of your needs before purchasing a traction adding unit.
