COMP Cams LS Series Retro-Fit Trunnion Upgrade Kit

Valve train technology leader introduces new premium trunnion upgrade for GM LS rocker arms to optimize both performance & durability

There’s no denying that the GM LS engine platform has proven itself as a performer. The valve train is no different, with an improved design that makes for a perfect combination of power and durability to complement the impressive cathedral port cylinder head design. The rocker arm design features a lightweight, yet stiff rocker body that is strong enough for most applications. However, when it comes to high performance racing applications, high rpm and high valve spring pressures can put the factory rocker arm’s trunnion under intolerable stress.

Enter COMP Cams® with a new LS rocker arm retro-fit trunnion kit that replaces the cageless, loose OEM needle bearings and powdered metal trunnion with a premium 8620 steel alloy trunnion and caged roller bearings for added durability. The new design from COMP Cams® utilizes caged roller bearings that greatly reduce the possibility of the bearing failure experienced with stock LS needle bearings, which can send loose needles throughout the engine upon failure.

Perfect for drag and circle track racing applications that mandate the use of stock engine components, this performance rocker arm modification is a “must have” upgrade for your LS factory rocker arms. As proof of success, for the last two years this rocker arm trunnion upgrade has been tested and performance-proven in the NASCAR GM LS spec engine series.

Features & Benefits:
• Replaces OEM powdered-metal trunnion with stiffer, more durable 8620 steel alloy material
• Factory needle bearings replaced with caged roller bearings to increase rigidity & reliability
• Designed for circle track & drag racing classes where stock engine components are mandated
• Performance-proven & tested in NASCAR GM LS spec engine series

Lunati LS Dual Valve Spring Kit

GM’s LS-Series V-8 engines are the most popular and fastest growing performance and racing powerplants since the original small-block Chevy. These plentiful, versatile engines have also spawned a huge and rapidly expanding aftermarket of power-increasing LS-designed products. One of the most power-rewarding ways to increase HP, torque and RPM in any LS V-8 is by installing a Lunati roller cam. This becomes the foundation for building a powerful LS engine that fully utilizes all the capabilities of aftermarket power enhancing products. Now Lunati offers LS enthusiasts the opportunity to take that cam change to extreme power levels with Lunati’s new LS Valve Spring Kits. Three new Lunati Dual Valve Spring Kits are available for GM LS engines. Each kit includes everything needed to maximize horsepower, torque, RPM and durability for mild to extreme applications. Each kit includes a set of Lunati Signature Series, tension-matched, Chrome Silicon Dual Valve Springs (Pt. No. 73925). The three kits come with either 4140 chrome moly, light weight tool steel Valve Spring Retainers or titanium Valve Spring Retainers, plus Lower Spring Locators, Machined Steel, 70 Valve Locks and Viton® steel-reinforced Valve Stem Seals, for positive oil control. Pt. No. 73925K1 features Chrome Moly, machined steel, heat treated retainers. Pt. No. 73925K3 features lightweight, machined Tool Steel retainers. Pt. No. 73925K4 comes with Lunati’s premium Titanium Alloy retainers, the lightest, and strongest available. Each of the three kits features Lunati’s finest Chrome Silicon, precision wound, micro-peened, heat-set, dual-coil valve springs. These 1.306” O.D. springs provide 153 lbs. seat pressure (measured @ 1.810”) and 400 lbs., open load (measured @ 1.150”). These competition-proven valve springs are designed to accommodate aggressive cam profiles with valve lifts of up to .660”.
