Low range gear ratios are approximately half that of high range. Rear-wheel-drive automobiles, including Chevy and Ford model muscle cars, were equipped with a live axle, instead of independent rear tire suspension. This type of system uses clutches instead of gears to adjust slip. Think of it as saying Kleenex when you mean tissues or Xerox when you mean making copies. Another type of differential, called a locking differential, uses dog clutches instead of friction plates to send power to each wheel. The Oldsmobile 4-4-2 (also known as the 442) is a muscle car produced by Oldsmobile between the 1964 and 1987 model years.Introduced as an option package for US-sold F-85 and Cutlass models, it became a model in its own right from 1968 to 1971, spawned the Hurst/Olds in 1968, then reverted to an option through the mid-1970s.

Some of the more well-known are GM's PosiTraction, Ford's Track-Loc and American Motors Corporation's Twin-Grip. "I had 4.10/posi before, and it wouldn't hook in 1st or 2nd with 295/50R15 BFG " ... My extra impression of a car hooking is the torque twisting the front end and the hooking the cars does to the left also from torque. Any ways, looking a the specs, what does 342 posi mean anyway? Because a limited-slip differential prevents sending too much power to one wheel, it keeps both wheels powered, rotating, and maintaining traction, even in off-road, uneven, and slippery environments. For POSI we have found 27 definitions. A limited-slip differential (LSD) is a type of differential that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts.. lmao, hell no. If the rear end has an open differential, the tag is on the left lower cover-mounting bolt. Owners of muscle cars in the 1960s and 70s took advantage of the benefits Positraction offered. When cornering or turning the inside wheel has less of a distance to travel than the outside wheel. 2003 Ford Taurus LX-General. Today's automakers minimize tire slippage by producing limited slip differentials in several types of designs, using friction plates and cones or gears. Positraction and limited-slip are both types of automotive differentials. Bob Brown has attended Johnson & Wales University in Charleston, S.C. for baking and pastry arts and DelTech Community College in Dover, Del., for construction management. Copyright 2020 Leaf Group Ltd. / Leaf Group Media. Differentials are located in the center of the front axle, center of the rear axle or, in some cases, both.
