Features
- Manufactured from high-strength, T-5 heat-treated, 390 hypereutectic aluminum alloy
- Allows a tighter fit and longer piston and ring life
- Diamond-machined pistons are held to plus or minus one gram weight and less than one-half-thousandth-inch (.0005") tolerances from piston to piston
- Each kit contains two pistons, pins, spiral-lock pin clips and Hastings moly rings
- Replacement piston rings sold separately
- KB pistons can be installed tighter than other pistons. This results in less piston rock and better ring seal. Please read instructions included with piston for correct piston clearance.
- Due to the thermal conductivity and design of KB pistons, special attention is required to the top ring end gap. Please read instructions furnished with piston for correct ring installation.

Poor quality, the book is already falling apart.
Format: Paperback
This is a review on quality of the book NOT the content.
I just got the book today and the binding on the cover came off immediately. It’s very poorly made!!!

Description is misleading
Format: Paperback
The description states that the book includes the access code. That is not true, the access code has been used and publisher is not honoring coffee
