KB Performance Pistons<br />
Now you can have the same pistons that have become synonymous with<br />
drag racing and high performance. Designed <strong>by</strong> the radical racer himself,<br />
Keith Black, these lightweight pistons are diamond machined and held to<br />
plus or minus one gram within the set. Skirt size tolerance from piston to<br />
piston is less than .0005". Made of high-strength T6 heat-treated, 390<br />
hypereutectic aluminum alloy, they yield better thermal efficiency with less<br />
expansion, and superior wear characteristics. They can run with less than<br />
.001" piston-to-wall clearance with no scoring - the tightest clearance in<br />
the industry. KB pistons can be installed tighter than other performance<br />
pistons. A close-fitting piston rocks less, supports the ring better and seals<br />
the engine for maximum power. When a loose fit engine is desired, the<br />
rigid skirt design of the KB piston allows the builder a choice without fear<br />
of piston damage.The thermal efficiency of the 390 alloy allows engine timing<br />
to be reduced and the tight clearance virtually eliminates piston noise.<br />
Sold in sets complete with 2 pistons, rings, wrist pins, and circlips.<br />

S&S Forged Piston Kits<br />
S&S pistons are designed with maximum piston/engine life and performance<br />
in mind. Features include:<br />
• Offset wrist pin to reduce piston slap and noise<br />
• Piston-to-piston clearance at the bottom of the stroke is concentrated in<br />
the rear piston so a longer piston skirt can be maintained on the most<br />
critical area - the rear of both pistons<br />
Fit Big Twins from 1936 thru 1999 with stock or overlength 35/8" Big Bore<br />
cylinders, and strokes from 331/32" (stock 74") to 43/4" as well as 45/8" stroke<br />
S&S Sidewinder ® kits. Each piston includes rings, wrist pin and wrist pin<br />
keepers. Replacement ring sets are sold each (one set for one piston).<br />
