Description
Set of 8 Wiseco RED Series forged pistons for the Chevy LS: 4.080 in (103.63 mm) bore, 1.105 in (28.07 mm) compression height and -20.00 cc crown volume. Rings and wrist pins are included.
What’s in the box
- 8 forged pistons
- 8 wrist pins (0.927 in / 23.55 mm diameter, 5115 steel, floating, Wiseco part S736)
- Piston ring set (Wiseco 4082GFX)
- 16 wire lock retainers (Wiseco W5595)
Matching it to your Chevy LS
Wiseco list this set for a 4.000 in stroke and 6.125 in connecting rods. Compression height plus rod length plus half the stroke comes to 9.230 in (234.44 mm): compare that with your block’s deck height to see where the piston sits at top dead centre.
Crown volume is quoted as -20.00 cc: Wiseco use a negative figure when the dish or valve reliefs add volume to the combustion chamber. Work out the compression ratio for your combination (chamber volume, gasket bore and thickness, deck clearance) before you order.
The bore size is the finished bore these pistons are made for, so have the block measured and then bored and honed to suit, with piston-to-wall clearance set to Wiseco’s figure for part RED0084X8.
Material: 2618 aluminium, the low-silicon alloy usually chosen for boosted and high-load engines (it needs more piston-to-wall clearance than 4032).
Forging: strutted design, with a coated skirt.
Ring grooves: 1.20 mm top, 1.20 mm second and 3.00 mm oil (steel top ring, ductile iron second ring and stainless steel oil ring).
