COMP Cams Valve Seals
COMP Cams offers a complete line of valve seals, from the stock GM O-rings to the positive-stop PTFE seals. They are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The O-ring seals use the standard retainer and oil splash shield. The umbrella seals are normally used when a larger-than-stock diameter spring is used. In the case of a double spring, the positive stop PTFE seals are used. For triple-spring applications, use the smaller-diameter Viton® seals.

Fel-Pro Valve Stem Seals
Fel-Pro valve stem seals are available in a variety of sizes, styles, and materials. These small components perform a valuable role—controlling the lubrication of the valve stems as they slide in the valve guide. Too little oil causes stem and guide wear; too much increases oil consumption and can cause a buildup of carbon. This can lead to valve seat damage and early valve grind. Order the replacement set recommended for your vehicle and engine application.

Trail-Gear Pinion Seals
Trail-Gear pinion seals are direct replacements for your leaking seal. These Trail-Safe seals feature a lip totally supported by a garter spring applying constant force over the full 360 degree circumference. This prevents any deflection gaps and stops oil from bypassing the seal lip. The outer seal lip acts as a secondary seal and keeps debris and other contaminants away from the inner seal lip. The outside diameter is 100 percent coated with high-temperature polyacrylate rubber so that it forms a complete static surface seal resulting in zero leaks and maximum longevity. The outer flange prevents the seal from being pushed too far into the differential housing. This is by far the most effective pinion seal on the market, and will help you keep your favorite trails free of oil.

Sikky Manufacturing LSX Header Gasket Sets
Sikky Manufacturing LSX header gasket sets are high performance seals for GM LS engine swaps. They feature multi-layer metal gaskets and all necessary bolts, designed to create a durable seal for aftermarket headers in demanding, high-horsepower applications. These gaskets use stainless steel layers and embossments to withstand extreme exhaust pressures, preventing leaks during rigorous use in swapped vehicles. Additional details: * Includes two gaskets (one for each side) and all 12 bolts needed for installation * Multi-layer steel (MLS) for superior heat and pressure resistance * Made specifically for LS-based engines (LS1, LS2, LS3, etc.) in vehicle swaps, often paired with Sikky's swap components * Stress-formed layers act as springs to maintain a tight seal under extreme conditions * When swapping a powerful GM LS engine into another vehicle (like a BMW or older GM), standard gaskets often fail due to increased exhaust heat and pressure. Sikky's gaskets provide a robust, reliable seal, ensuring performance and longevity in these custom setups.
