Mahle Original piston ring sets are designed to be installer-friendly. They are pre-lapped to seat immediately, virtually eliminating break-in time. Ring materials and coatings, as well as ring tension, are all optimized for reduced friction and extended life in each application. The compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining to enhance contact. The CP-20 oil ring assemblies feature a 20 degree ear angle, an exclusive feature that provides the best possible side seal against the cylinder wall, and a special chemical polish on the oil ring expander offers enhanced oil drain back. Mahle Original piston ring sets provide unmatched quality and ease of installation, making them the rings of choice for today's engine builders.

PowerBond Street Performance harmonic balancers bring bonded balancer technology within the budget of every performance street engine builder. They are also perfect for limited spec race classes, such as late model stock that require an OEM-style balancer. The bonded dampening rubber in every balancer eliminates spinning and component separation giving reliable performance in engines used up to 6,500 rpm. PowerBond Street Series balancers use high-strength SG (Spheroidal Graphite) iron rings and hubs that are pressure-bonded, and high-pressure, low-cure that features a natural rubber developed in our laboratory. All PowerBond Street Series balancers feature an etched black primer with a 2-coat clearcoat and fully etched laser timing marks.

The OE rocker arm bearing design is a proven weak link in high-performance LS engines because the bearings are unable to cope with high lift cams, higher valve spring pressures, and sustained high-RPM use. Plus, the uncaptured design allows the needle rollers to be ejected into the crankcase, potentially causing catastrophic engine damage. One way to fix these issues is with a full set of high-quality roller rocker arms. However, many builders prefer the lower cost and lightweight durability of stock rocker bodies. That's where Trick Flow's far less costly solution comes in. The Trick Flow® rocker arm trunnion upgrade kit includes 16 CNC-machined trunnions that are heat-treated and precision ground to tighter tolerances for reduced wear and significantly improved rocker arm control. Precision needle roller bearings withstand high performance cams, valve springs, and repeated high-RPM blasts. They are held captive by extra wide circlips to prevent the bearing walk-out problem of the OE design. The Trick Flow® trunnion installation kit takes all the hassle out of removing old trunnions and installing new ones, with easy installation using just a bench vise instead of a cumbersome hydraulic press like other kits. Best of all, no modification are required to the OE rocker arms to use these upgrade and installation kits! Features Include: • CNC Machined Trunnion - Heat Treated & Precision Ground • Tighter Tolerance & Radial Clearance • Captivated bearing for reliability • Designed for higher stresses and high RPM use • Improved rocker and valve control
