If you're looking to step up your ride's traction game, the Yukon Dura Grip is where it's at. This limited slip differential brings a solid mix of smooth operation and aggressive grip, making it perfect for tackling all sorts of terrains. Whether you’re cruising down the highway or hitting the backroads, this bad boy gives you the confidence to push your vehicle to its limits.
What I really appreciate about the Dura Grip is its durability. It's built to last, thanks to a tough nodular case and those forged 4320 chromoly spider gears. Plus, if you ever need to refresh it, this differential is completely rebuildable. So, when the time comes, you can keep it running strong without having to shell out for a whole new unit.
Now, let’s talk specs. This unit fits a 3.73 gear ratio and down, and it’s compatible with thick gears, which is a nice touch. It’s designed for GM vehicles with 17 spline axles, so if you’ve got a classic like a '55 Bel Air or a '64 Corvette, you’re in luck. The composite clutches provide that limited slip action you want without sacrificing smoothness. And don’t worry about the strength; the gears are cut to deliver maximum durability in any situation.
