Don't take your driveshaft for granted. Massive amounts of torque are applied to the rear wheels by a high torque, big horsepower engine. When you build horsepower, your driveshaft must be built to take the abuse. Inland Empire only builds driveshafts and related componenets, so you get a professionally built driveline product. Inland Empire pinion yokes and transmission yokes are made from forged 1350 steel to give you a product that can withstand abuse! You can get Inland Empire driveshafts and yokes from JEGS at everyday low prices.
