Choice Of Standard Duty Or Severe Duty Output Shaft
Core Exchange Required
Realize "huge" improvements in acceleration by just bolting-in a 3.90 axle
ratio differential. C5's equipped with 2.73's will get up to a full second improvement in 1.4 mile E.T.'s, while 3.42 equipped cars will get up to 4 tenths of a second improvement. There are two
options available for the output shaft; for six-speed cars with engine horsepower in excess of
450 we suggest the severe duty version, automatic equipped cars, unless running nitrous, superchargers or drag slicks, will be properly equipped with the standard duty version.
Reprogramming of your speedometer will be required and we suggest the Hypertech Power Programmer (it's easy to do). A $850.00 core deposit will be added to the price of the differential. The core deposit will be refunded upon receipt and inspection of a rebuildable core ONLY if it is returned within 14 days of date received . Sorry, no exceptions. Cores with axle ratios of 3.42 and 3.73 will be accepted. Please call our customer service department for core return instructions and address.
