Torque, you have to love it. It’s what pushes us into the seats during acceleration and puts the never-ending grins on our faces. Chances are if you’ve already upgraded the transmission to handle the additional grunt, then the rearend is the next area you’ll want to address. Beefier axles, steeper gears, and a huge choice of differentials can make it tough to choose from, however the manufacturers listed here offer a variety of choices for your every need.
Whether you’re looking for a mild or the most robust rearend for dragstrip duties, Strange Engineering offers it all. For late-model F-body fans, you can get into a fully assembled (less brakes) 12-bolt with 3.150-inch ID housing ends, 33-spline axles, choice of studs, and matching 33-spline superstrength differential. You also get a choice of either the three- or four-channel ABS, caliper mounts, including an S-series yoke, crossover U-joint, U-bolts, chrome cover, and standard gearset with Lucas oil. Leaf-spring applications are similar and come with 30-spline axles and Torque-Line posi unit, and 1/2 -inch studs. Both rearends are also offered with drag racing–only configurations that come with 35-spine Pro Race Axles and spool.
