Installing a Lock-Right is a fairly straightforward job, and the best part is that it doesn't require you to replace the differential or go through the tedious gear setup process. All you need to do is replace the existing spider gears with the Lock-Right. If, however, you need to change gears like we did, a complete gear setup sequence will be necessary.

The Lock-Right installation instructions, included with the kit, are easy to follow, but you may want to have a service manual for the rearend you are working on. With the exception of a dial indicator and magnetic base (if you're changing gears), the required tools to install the Lock-Right are probably sitting in your garage.

This particular rearend housing came with the engine we bought for our Valiant project. It is an A-Body rear, complete with big bolt pattern axles, although the open differential and highway gears definitely needed help.
