Lightweight. Strong. Those two words typically don't go together when describing performance racing components. Now add the word "ECONOMICAL" into the mix and you have just described the Moser Engineering Super Light Weight Nodular Case. This direct replacement case is perfect for those circle track racers and street rodders concerned about saving unsprung weight without sacrificing strength. The Moser 'SUPER LIGHT' Case weighs in at under 22 lbs! In fact it is almost 2 lbs. lighter than most OEM stock cases, but is much stronger! Intended for low to medium horsepower applications (Up to 600 hp), it is manufactured from the same nodular material used in our Performance Nodular Iron Cases. Utilizing 1/2" Main Cap Bolts, this Case is reinforced around the Pilot Bearing, and utilizes the larger 3.062" diameter Carrier Bearing.
