Manley Stainless Steel Valves
Designed to outflow stock valves and feature chrome or nitrided stems to eliminate galling. Impervious to heat and unleaded fuels. Sold in pairs.

Manley Thin-Stem Valves for Shovelheads
These valves use smaller-than-stock stem diameters to achieve lighter weight and increased flow. They require the use of the special thin-stem valve guides (listed below), thin-stem keepers (CCI #99-294) and Manley lift kit CCI #99-219 or #99-226. Sold in pairs.

Note: CCI #99-038 valve has a steep, tulip-shaped head for maximum flow in high RPM engines.

Manley Valves for 883cc/ l2OOcc Conversion
To fully benefit from an 883cc to 1200cc conversion, you need to install larger valves. These 1.48" exhaust and 1.715" intake valves from 1200cc Sportster® models are .060"-shorter-than-stock for the 883cc heads. Forged one-piece stainless steel with chrome stems and hardened tips. Sold in pairs.

Manley Performance Valves for 1970 thru 1985 Sportster® Models
One-piece stainless steel valves designed for maximum flow in high RPM engines. CCI #99-037 has steep tulip-shaped head designed for better flow while CCI #99-002 has a flatter head shape better suited to street use. CCI #99-003 is .080" longer than the stock intake valves. Sold in pairs.

Kibblewhite Black Diamond® Valves
One-piece stainless steel stellite-tipped steel valves are impregnated with a special German process that develops a surface .002" deep in the valve itself with just .0002" surface build-up to improve wear properties and reduce friction. The surface provides resistance to corrosion and has wear properties superior to hard chromium and nickel-plating. Valves are lightweight with sectional profiles that provide excellent flow characteristics. Sold each.

Kibblewhite Razorback™ Valves
Made from one-piece forgings of heat and corrosion resistant EV8 stainless steel. Fully CNC-machined with hard chromed stems. Sold each.

Kibblewhite Black Diamond® Specialty Valves Thin or thick stem, one-piece stainless steel stellite tipped impregnated valves for Shovelhead models 1966 thru 1984.

Black Diamond® Conversion Valves for Evolution® Sportster® Models Use these Black Diamond® valves when converting your Evolution® 883cc Sportster® model to 1200cc. Get all the benefits of high-tech, high-quality valves. Sold each.

Crane Complete Valve and Spring Kits The key to maximizing high-performance gains is to match components to one another. Crane has taken the guesswork out of matching critical valve train parts with these kits that include springs, retainers, valves and locks.

Crane Engine Valves Crane's engineers have matched the materials in these valves to the different operating requirements of the head, stem and tip. The result is a 'two piece' valve that is friction-welded at mid-stem using a technique that creates a bond stronger than the material itself, The valve heads are made of 21-2N stainless alloy for its high-temperature properties, and SAE 8645 martensitic hardened steel alloy (50 RC Rockwell hardness) is used for the upper valve stem to minimize wear in the tip and keeper areas. The surface of the stems are either hard chrome plated or nitrided to resist galling. For extreme duty, Crane also offers exhaust valves with Inconel 751 heads and lower stems in place of the stainless alloy. Sold each.

Premium® Stock Replacement Engine Valves Premium® engine valves exactly duplicate Original Equipment specifications for materials and machining but at a lower cost. Each valve is permanently marked with its part number to simplify stocking and reordering. Available for Knucklehead, Panhead and Shovelhead motors as well as the very latest Evolution® powered Big Twin and Sportster® motors. Sold each.

RevTech® High-Performance Engine Valves RevTech® valves combine the latest in engineering (including the ability to deliver high-performance with no lead or low lead fuels) and the widest range of applications possible with the fewest part numbers. The valves are true, one-piece stainless steel, and the stems are completely nitrided for superior resistance to galling at high cylinder head temperatures. The valve stem tip, rather than just being a swaged-on 'button,' is a fully-supported cup of stellite, formed by first machining a recess into the stem, then filling it with super-hard stellite material. The heat-treated material forming the cup firmly supports the stellite and distributes the impact shock of the rocker arm over a wider area. Each valve is clearly marked with the part number on the stem. Each part number replaces several Original Equipment numbers to simplify stocking. For example, the stems on the late Shovelhead exhaust valves are machined to .375" diameter, which fits all early and late-style valve guides when new guides are correctly reamed to final size. With a minimum number of valves, all 1948 thru 1981 Big Twin and Sportster® motors can be upgraded to run on unleaded or low lead fuels with your own choice of valve guide material. Sold each.

Rowe Engine Valves
Top quality American made valves for Big Twins and Sportsters®. All Rowe valves are one-piece drop forged construction and precision machined. Available with standard roller-burnished head and stem or with black Melonite coated stem. Black Melonite is a nitrite equivalent with excellent wear and lubrication qualities. Each comes individually color boxed complete with assembly lube. Sold each.
