Review master-cylinder applications separately for ABS and other system requirements. Compare compounds and kit contents only within the correct brake-package application.Bilstein Dampers and Chassis ProjectsDisplayed Bilstein B6 and B8 references have separate generation, position and production coverage. KYB, SuperPro, Cusco and SPL references support different damper, bush or alignment tasks. Match actual chassis and factory equipment, then review installation scope and any required ...

Shop Supertech engine-build components at Black Ops Auto Works. Explore intake and exhaust valves, valve-spring kits, guides, retainers, pistons and supporting hardware. Coordinate the selection with your engine builder’s measured specifications and complete cylinder-head or short-block plan.Intake and Exhaust Valve ChoicesChoose intake or exhaust valves by exact engine code, head diameter, stem dimensions, length, material and groove arrangement. Compare standard and oversized options using the cylinder head’s measured requirements. Coordinate any oversize selection with the builder’s machining plan, valve guides and seats before ordering the complete set.Valve Springs, Retainers and LocksBuild the spring package around the camshaft and the cylinder head’s measured installed height, pressures and clearances. Single, dual, beehive and conical springs have different mating-component requirements. Check whether the selected Supertech spring requires its specified retainer, seat or loc...

Match the valve-spring package to your camshaft and cylinder head with Supertech, Brian Crower, GSC, Ferrea, COMP Cams, Skunk2 and other listed references. Compare single, dual and beehive designs, separate retainers and matched kits. Choose the required spring pressures and geometry for the complete valvetrain, not a higher-pressure spring by default.Single, Dual and Beehive ChoicesSpring design must suit the cam profile, valve mass, operating range and installed height. A dual spring is not automatically appropriate for every upgraded cam, and a beehive spring still needs the correct retainer and seat.Vehicle/engine-specific kits cover different hardware combinations. Some Supertech references explicitly retain OEM retainers and seats; other kits supply matched retainers or locators. Compare contents before ordering separate pieces.Retainers, Seats and LocksCompare titanium, steel and other named retainer references by exact spring dimensions, lock angle and valve-stem/groove arra...

Plan a coordinated cylinder-head service or performance build with engine valves, guides, seals, springs, retainers and keepers. Browse Supertech, GSC Power-Division, Ferrea, Brian Crower, COMP Cams and other listed references, plus valve covers and sealing hardware. Start with the engine, cylinder heads and actual camshaft/valve arrangement.Valves, Guides and Oil SealsChoose intake and exhaust valves by complete dimensions, material and groove design. Standard and oversize head diameters have different machining needs; a larger valve is not automatically a drop-in or a power improvement.Match guides to the head bore, valve stem and approved installed geometry. Seals must fit both stem and guide, with correct intake/exhaust coverage and any integrated-seat requirement. Use the exact companion references when a manufacturer specifies a matched combination.Springs, Retainers and LocksCompare single, dual and beehive spring packages against the cam requirements and measured installed h...
