2003 Street Rod Rears

One owner since 1958, Winters Performance Products manufactures the best quick change rear ends ever made. Mostly used in circle track racing, quick change rear ends work very well in street applications. In most cases the Championship 10" Quick Change is more rear end than you'll ever need (800+hp). Our V8 Quick Change is rated at 550 hp while the 3.08 and the Heavy Duty Championship Quick Change can be used in more severe applications (1000+hp). Keep in mind severe shock loading (drag racing) will shorten the life of all drive line components. All Winters Quick Change Rears use spiral bevel ring & pinions, the most efficient ring & pinion available. Pinion placement of a spiral bevel ring & pinion uses less power, is more efficient, and runs cooler than hypoid ring & pinions. Hypoid style ring & pinions create more sliding action, increasing heat and power loss.
•What type of oil should I use in my Winters Rear End? Use a good quality lube, such as Winters 80-90-140 semi synthetic with moly. •What oil level should I maintain in my Winters Rear End? At two places. 1. The rear end cavity. 2. Quick change gear cavity. (see figure 1 below) Do Not over-fill!! Too much tube causes excessive heat! Full Size Rears Maintain oil level at 2" below axle center line. Make sure the car is level when checking oil. V8/Mini Maintain oil level at 1 3/4" below axle center line. Make sure the car is level when checking oil.
•How do I fill my Winters Rear End and quick change gear cavity with oil? The fill plug is located on the left side bell. The level plug is in the right side bell. Optional pinion inspection plug in the right bell may be used as a fill plug. Do not use inspection plug to determine fluid level.
•Ring Gear Bolt torque specifications. Threaded Ring Gear Bolts-60 Ft. Lbs. using red thread lock. •Thru bolt torque specifications. Full size rears (7/16" thru bolts) 35 Ft Lbs. Mini/V8 (3/8" thrubolts) 25 Ft Lbs. •Side bell stud torque specifications. Full size rears (7/16" studs) 35 Ft Lbs. Mini/V8 (3/8" studs) 30 Ft Lbs. •How do I install a side tube in a side bell? DO NOT TORCH! Bell cracking may occur. Place the tube in a 5 gallon pail filled with ice. Make sure that the bell is clean and free of chemicals or flammable materials. Heat the side bell in an oven to 270-300F. Vaseline the bell bore and drop the tube into the bell. •Can I weld brackets to my steel side tubes? Yes. Weld a series of 1/2" long "tracks" along the bracket starting at the ends then alternate back and forth towards the center. Long continuous welds will heat and "draw" the tubing, causing distortion. •Can I use helical quick change gears in my Winters Rear end? Helical cut gears, although not recommended in racing applications, do have their advantages in street applications. Quick change gear noise at highway speeds can be reduced with helical cut gears versus conventional straight cut gears. Q.C. gear end play (clearance) must be limited to .010 max.
