posi rear end kit

Anybody heard of a kit to convert a stock 65 chevy SWB rear end into a posi rear end? If so wear can I get one and how difficult is it to do it?

Re: posi rear end kit

There is no special kit needed to install a posi into a '65 or newer truck 12 bolt. The '63 & '64's require changing the side spider gears. All you need is a posi unit for a truck 12 bolt. The truck 12 bolts were used from '63-'82. You may also need an installation kit, which will have new bearings and seals. The typical posi unit will require a professional to install correctly, unless you posess the necessary skills and tools to do so. An exception to that is the lock-Rite unit that will fit into your existing carrier. There are a number of sources for either of those such as , Summit Racing, Jegs, Randy's Ring and Pinion, Reider Racing, Drivetrain Specialties, Drivetrain Wharehouse, etc.

Nope. The most common stock gear in these C10 trucks is 3.73's. 4.10's were an available option.
