How Do I Know What Kind of Kit I Need? 

As you probably know, there are three different levels of rebuild kit you can get. As we mentioned, this particular Perkins rebuild kit is an out-of-frame kit. This means that it includes the most components of all the kit levels. This type of kit replaces a lot of components in your engine and allows for even wear. It takes longer to complete this job, but it gives you the peace of mind knowing that you've replaced everything you might need!

There's also the option of an inframe rebuild kit. It doesn't take as long as a complete out-of-frame overhaul, but is still a bigger job than a re-ring kit. The exact components of this kit depend on your engine type, but they will always include pistons. As you can probably guess, an in-frame rebuild happens with the engine in the frame. This saves you time and labor. 

The smallest rebuild kit option is your re-ring kit. This type assumes that your pistons are still good. It's good for when your engine just needs a bit of a pick-me-up. Re-ring references the fact that you'll need to replace the piston rings, even though you're using your old pistons. Like the in-frame kit, the exact contents depend on the engine type.

*Note: The Perkins kit described in the sections above is an out-of-frame rebuild.
