Pistons,Kb Perf 9.6:1 Std Bore Bt Evo 80Ci W/Pins,Locks,Rings 3.498"Std Bore Hi Compression

Spawned from this successful manufacturer's line of automotive pistons
Lightweight permanent mold cast pistons
Manufactured from Hypereutectic 390 Alloy, contain 16-18% silicon, and heat treated to T6 specifications producing a stronger than stock piston
Special alloy compositon keeps heat confined to the combustion chamber and reduces heat transfer to the piston Fitself producing a cooler running piston
Can be fitted with a clearance as small as .00075
Piston expansion is reduced by as much as 20% over conventional pistons
Less piston rock, better ring support, more durability and better retained compression for maximum power
The key feature to these pistons is the accumulator groove between the top and second ring which averages the normal pressure between the first and second ring, keeping the pressure low enough to prevent lifting of the top ring while maintaining preload on the second (oil scraping) ring
Each set of pistons includes wrist pins, spiral locks, engine assembly lube, and Hastings Moly rings
Wrist pins measure .792 O.D. on single cam models and .927 on Twin cam models
Sold in sets as shown
Replacement ring sets availableKB Performance Pistons

Pistons,Wiseco 9.5:1 +.010"Os Spt883/1200Cc W/Pin,Lock,Rings 3.497"Std Bore Hi Compression
All Wiseco pistons are forged from hi-silicon aluminum alloy for superior strength and dependability. The unique piston shape allows tight piston to wall clearances for quieter operation. This shape combined with a top quality ring package and computerized machined anti-detonation grooves offers you the most technically advanced piston kits available. Wiseco pistons are available with either Hastings X Style or Wiseco XC Style piston rings. All replacement ring sets include rings for one piston only. Must use 63026A when replacing piston pin lock rings in all Wiseco pistons. Hastings X Style rings are not interchangeable with Wiseco XC Style rings. All piston kits listed are designed to be used with stock stroke flywheels only. Most Wiseco pistons are machined with valve pockets that are deeper and larger than stock. These pockets provide adequate valve clearance for most high lift cams, but as with any high performance upgrade all clearances must be checked. All 883cc to 1200cc overbore and 84ci Big Bore kits do not require cylinder head modification or flywheel rebalancing unless deemed necessary by the service technician. The 84ci Big Bore kits require Big Bore cylinders and crankcases must be bored to accept the larger cylinders.Piston Kit.
