IMPROVED HYDRAULIC ROLLER LIFTERS FROM CRANE CAMS

The engineering and manufacturing teams at industry leader Crane Cams have taken many of the important attributes found in the firm’s racing rollers and incorporated them into a new generation of hydraulic rollers for street applications. Benefits include straighter tracking, increased durability and higher RPM potential when a very stable valve train is employed.

Visually, the differences between these and the previous generation are striking. The lifter bodies are fully CNC machined from 8620 billet steel and feature an improved surface finish. Heat-treated steel guidebars with a Monel rivet and flange retaining system add to the durability of Crane’s hydraulic roller lifters. A precision-valved plunger assembly optimizes RPM potential, while a heavy-duty roller wheel and bearing assembly track true, thanks to the lifter body’s strength and superior guidebar system.

Retrofit hydraulic roller systems are available for small and big block Chevy, Ford and Mopar applications, as well as replacement models for engines originally equipped with hydraulic rollers. Complete information can be found on the newly revamped Crane Cams website and personalized technical assistance is available toll-free by calling 866-388-5120.

LIGHTWEIGHT TENSILEMAX & H-13 TOOL STEEL SPRING RETAINERS FROM MANLEY

The valve train experts at Manley Performance have developed two special steel alloy valve spring retainers that are almost as light as titanium, but with greater resistance to wear. They are also great for racing applications where titanium valve train components are not permitted.

For Super 7° applications Manley offers retainers for double valve springs made of proprietary TensileMax™ alloy. These are available in standard, convoluted, and double convoluted designs—which are comparable weight-wise to standard titanium retainers. The material is specially heat-treated to provide a hardness of Rc 52-54 to prevent retainer wear. A unique impingement process improves fatigue strength and promotes an oil film between the spring and retainer.

Applications utilizing a 10° keeper angle are handled with Manley’s new lightweight H-13 tool steel retainers. They are 33% lighter than standard 10° steel retainers and only 2-4 grams heavier than titanium versions. They are heat-treated to a Rockwell hardness of 56.

Manley manufactures both steel and titanium valve locks in 7°, Super 7° and 10° configurations, as well as a variety of steel and titanium valve spring retainers. For additional information call 732-905-3366 or visit the firm’s website at www.manleyperformance.com. [3/3/11]

LOWER YOUR MOPAR & IMPROVE HANDLING!

Less than a year after introducing a complete line of track-tested, performance-proven suspension systems for Mopar A, B and E-body platforms, Hotchkis Performance has unveiled the final component for its Chrysler suspension lineup - high-performance torsion bars. These bars were developed in direct response to customer demand for a high-performance torsional spring to match Hotchkis sport sway bars, geometry-corrected A-Arms and leaf springs and Total Vehicle Systems.

Unlike many muscle cars of the era, 1960s and '70s Dodge and Plymouth suspension relies on front torsion bars to set ride height and control cornering and ride stiffness. Worn torsion bars can result in uneven ride height and poor vehicle control. The engineers at Hotchkis have designed a 1.03-inch bar to replace stock torsion bars and compliment the handling upgrades of the Hotchkis Mopar TVS system and its individual components. Hotchkis offers the new torsion bars to fit most 66-76 Dodge and Plymouth platforms.

Hotchkis Torsion bars are built out of high-strength steel and are finished in durable black powdercoat. Kits include a pair of forged, heat treated 1.03” torsion bars, polyurethane seals, and new retaining clips. While Hotchkis Torsion Bars work extremely well on their own, they work best when paired with Hotchkis Sport Sway Bars, Geometry-Corrected Leaf Springs and Total Vehicle Systems. To preview the entire line of Hotchkis Sport Suspension parts and components, please visit www.Hotchkis.net, email sales@hotchkis.net, or contact Hotchkis Performance, 8633 Sorensen Ave, Santa Fe Springs, CA 90670, 877-4-NOROLL.
