For those looking for a serious upgrade to the internal components of their LS1/LS6, check out the ICON Elite Series pistons from United Engine and Machine (UEM). The ICON Elite series pistons offer the utmost in reliability, even in the most extreme of conditions thanks to the careful process used by UEM.
Through the use of 2618 aluminum material, the ICON Elite series pistons are built to handle what your LS1/LS6 can dish out. When it comes to machining, UEM is a leader and their products depict their attention to detail. The pistons feature CNC machined valve reliefs and crowns, mini grooves, and diamond CNC turned skirts.
The pistons feature an anodized top ring groove and piston crown. By anodizing the top ring groove, the ICON Elite series pistons are more durable as this process directs heat in the piston crown. Essentially, this is a fail-safe design that helps to reduce the impact of detonation conditions where heat can create chaos through “micro-welding.” In addition to the improved combustion function, the ICON Elite series pistons feature another innovative coating, the Line2Line Adaptive Skirt Technology Coating helps to reduce further friction and therefore improving heat transfer. This process reduces the friction between the piston and cylinder wall.
In addition to the careful focus on coatings, UEM’s ICON Elite series pistons feature an upgraded wrist pin. This workhorse part is not as glamorous as other performance parts, but it is one of the most critical. The rod and wrist pin bear the brunt of the crank’s force, and therefore it is vital for the wrist pin to be capable of withstanding that force. Along with above mentioned features, the ICON Elite Series pistons include an accumulator groove, dual forced pin oiling, lateral ports in high compression applications, and spacer rings for shorter compression height pistons.
