9-Inch Bolt-In Sport Rearend - How To Install A 9-Inch Rearend
The 9-Inch Factory Makes It Easy With Their Bolt-In Assembly
For Brett, the 9-inch added strength, improved braking at the rear, and a gear upgrade from stock 2.80s to 3.50s for better off-the-line acceleration from his 289-powered Mustang. After a week or so of driving with the new rearend, Brett said, "I can tell a definite increase in the get up and go! It feels so much stronger. It is nice to go down the road and not hear that old hum-hum coming from the back."
