What is a quick change rear end? // Winters Quick Change Tech 

They want costs to go up to make the sport less attractive

The rear shown is a smaller V8-size rear, which uses 6-spline gears. The Late Models run our bigger 10-inch rears with 10-spline gears.

The reason is at the bottom is for lubrication.

Absolutely-our #1 gear set (for both 6- and 10-spline) is a 1:1 ratio. If you visit winters performance.com and click on "Gear Charts" you can view a PDF with all available ratios.

@@wintersperformanceproducts thanks for responding! I’m going to use a fwd ls4….mount it mid engine turn it long ways remove one cv axle and connect the other side to a winters differential.

The rule of thumb is: • V8 size (8-3/8" ring & pinion), the rear shown in this video, is rated to 600hp • Champ (10" r&p) is rated to 1,000hp • Champ HD (or a Champ equipped with some of the available heavy duty options, like a heavy duty lower shaft) is rated for over 1,000hp But as you said things like slicks, trans brakes, how much the car weighs, etc. all play a role. If you're running a '32 Ford with 550hp, a T5 and pie crust slicks, a V8 rear will likely be just fine. If you're running a '68 Camaro big tire car with 550hp and a trans brake, you're going to want a Champ or Champ HD rear even though you're under 600hp. Every rear is built to order. If you've got a specific application in mind, give us a call or shoot us an email and we can get all your details and build you a rear that will live.
