SFI-RATED Racing Steel Dampers

PQx® SFI-Rated Racing Steel Dampers
PRW SFI Certified steel dampers are perfect for the weekend warrior or the all out racer. Unless otherwise identified, this series of steel-elastomer racing dampers is OEM compatible and designed to work with the accessories and mounting brackets specified for the model years identified. Many features have been added to broaden the spectrum of fitment and adaptability. The inner hub and outer ring are manufactured from high quality billet steel or forgings, with heated elastomer injected under high pressure between the two component parts. Inner and outer grooved ridgelines further secure the inner hub to the outer ring. All dampers feature primary laser etched timing marks and useful timing indicators generally provided at 90°, 180°, and 270° whenever possible. Some models include secondary timing marks for ancillary keyways or expanded model year applications. These products are available in black automotive grade epoxy.

  • Meets SFI 18.1 specification
  • Easy to read laser engraved timing marks
  • Accurate crank bore for a proper pressed fit
  • Manufactured from high grade billet carbon steel forgings
  • Injected with elastomer between the inner hub and outer ring
  • Available in black epoxy or polished steel and epoxy clear coat
  • Externally balanced dampers include removable counterweights

Tech Tip: What's the difference between PRW's High Integrity and High Inertia Designs? Both are manufactured for high-horsepower applications. High Integrity designs are lightened for quicker throttle response. Perfect for off-road, road racing or use on the street. The High Inertia designs are manufactured with a robust solid flat plate of cold-rolled steel for harder drag race launches and improved 60-foot times.

Tech Tip!: PRW Pro Series rocker arms are designed for heavier valve trains, higher spring pressures, roller cams and lifters. The fulcrums are matched to the precision bearings to support operational loads above 650 lbs. Keep in mind that operational loads far exceed open spring pressures. A rocker arm rated at 450 lbs of open spring pressure operates at a much higher operational load; with the higher RPM comes more load.

SPECIAL NOTE: Open Spring Pressure Ratings (OSPR) are determined by camshaft and pushrod manufacturers' published ratings. Not designed for use with OEM-Rated pushrods. High lift roller cams may require 210 degree specialty pushrod ends.


Modern Muscle Rocker Arm Systems
PQx® Mopar Modular HEMI® Rocker Arms
These specialty rockers are investment cast from alloy steel with siliconebronze bushings that incorporates standard OEM oiling. The surface of each rocker is tumbled to reduce stress risers and the top-lines are hand-polished for a professional appearance. The system will support high-performance valve springs that exceed the limit of hydraulic lifters. If utilized with solid lifter rollers, final valve lash adjustment requires the use of “lash caps”. Pre-assembled for easy installations.

• Hand polished
• Investment cast
• Tumbled surface to reduce stress risers
• Requires no additional machining to your
cylinder heads or spark plug towers

SPECIAL NOTE: OSPR (Open Spring Pressure Rating) assumes that the engine builder is utilizing equally
matched component parts throughout the valvetrain assembly. Pro-Series rocker arms are designed for
aftermarket high-performance pushrods.


SPORTSMAN SERIES ROCKER ARMS
PRW Sportsman Steel Stud Mount Roller Tip Rocker Arms are the ideal choice for a large cross-section of engines; whether it is a mild street rebuild or the performance requirements of off-track, circle track and drag racing. The PRW 4340 chromoly steel rocker bodies feature a longer pivot slot for higher lift cam-shafts and are much stronger than stamped steel, so rocker arm flex is negligible. The roller tip minimizes scrubbing (the result of the valve stem pushing hard against the valve guide), reducing friction and freeing up an additional 15 to 30 horsepower over stock rockers.

SPECIAL NOTE: Open Spring Pressure Ratings (OSPR) are determined by camshaft and pushrod manufacturers' published ratings.

  • PRW ROCKERLOCS™ included
  • Roller tip minimizes scrubbing
  • Rated at 350 lbs open spring pressure
  • Stronger than stamped steel rocker bodies
  • 4340 steel rocker bodies and heat-treated pivot balls
  • Excellent performance alternative compared to stock rockers

Tech Tip!: Never install new rockers dry. They must be lubricated during initial start-up with the proper lubricant to avoid permanent damage. All PRW rocker arms should be thoroughly cleaned and soaked in oil prior to installation. Utilize CMD Valve Train Assembly Lube (Part #’s 1299882 $4.07 & 1299884 $20.36 Refer to page 37) on each rocker arm, pivot ball, pushrod cup and roller tip to prevent damage to new parts.

FORD SPORTSMAN ALUMINUM FULL ROLLER TOCKER ARMS

PRW Sportsman Adjustable Pedestal Billet Aluminum Rocker Arms for Ford (5.0L) & 351 Windsor engines are manufactured from high strength 6061-T6 billet aluminum and utilize an adjustable pedestal that will help prevent excessive side-to-side movement of the rocker tip on valve. Each rocker is specially machined to allow for larger springs and retainers with full friction reducing needle bearings for added durability. The nose rollers and shafts are Cr40 steel, heat-treated and hardened to resist the severity of racing and to minimize scrubbing. Each rocker body is ceramic media polished, assembled and carefully inspected to provide our customers with some of the finest quality available to the racing and performance industry.
  • 1.6 ratio
  • Features 5/16” studs
  • Fully adjustable pedestal
  • Chromoly pushrods required
  • Manufactured from 6061-T6 billet aluminum
  • Features full complement friction reducing needle bearings

SPECIAL NOTE: Open Spring Pressure Ratings (OSPR) are directly related to camshaft and pushrod manufacturers' published ratings for equally matched component parts.

PRW stud mount aluminum rockers are specially machined to allow for larger springs and retainers with full compliment needle bearings for added durability. The nose rollers and shafts are Cr40 steel, heat-treated and hardened to minimize the wear that naturally occurs between the roller tip and the valve stem.

  • PRW ROCKERLOCS™ included
  • Chromoly pushrods required
  • Rated at 650 lbs open spring pressure
  • Available for self-aligning applications and in split-sets
  • Wide assortment of ratios to suit almost any cam profile

SPECIAL NOTE: Open Spring Pressure Ratings (OSPR) are directly related to camshaft and pushrod manufacturers' published ratings for equally matched component parts. Pro-Series rocker arms are designed for aftermarket highperformance pushrods.

Tech Tip!: Many aftermarket and OEM style cylinder heads easily adapt to various stud mount rocker arm applications, other than those published by the manufacturer. PRW Big Block Chevrolet rocker arms (for example) are commonly used by machine shops and engine builders on many of the Ford Boss 302, Modified engines and Big Block 429-460 cylinder heads. Before purchasing rocker arms for your engine, consult with your engine builder to confirm their preference.
