Through-Rod Shock

One of the issues all shock tuners have to deal with is the fact that as the shock compresses, the rod takes up volume inside the shock body. That’s the reason there is always some type of gas inside the shock. You have to have something that will compress when the rod extends into the shock body because the shock oil won’t.

But Penske’s Through-Rod Shock design eliminates the need for that because the rod extends all the way through the shock body so the volume inside the shock body never changes. With this shock design, fiddling with gas pressure is no longer an issue. The one drawback is that the through-rod system won’t work with every car—especially if you have clearance issues above the shock. The through-rod also won’t allow the shock to be mounted in double shear.

Every year the racing industry uses the Performance Racing Industry trade show held in early December to debut new products that will be available to racers and engine builders for the upcoming racing season

Digital Gauges

Currently, Auto Meter’s new digital gauge readout is designed specifically for NASCAR Sprint Cup Series cars because it ties into the engine management system they use, but we don’t doubt that we’ll be seeing something like this for Saturday night racers before too long. This is more than just a fancy video screen with some gauges on it. Auto Meter has programmed this unit so that it changes the readout based on the situation. For example, if the engine is at low rpm levels, the tach redlines for your programmed pit-road speed. Or while the oil temps are low, the unit assumes you are warming the engine and the oil temp gauge moves to the normal position for the tach for easy readability. Warning lights and gauges can all be programmed to your specific parameters. The panel is three times brighter than an iPhone and glare resistant, so it should always be easily visible to the driver no matter the sun’s position.

Sprint Car Front Drive

Here’s an item that’s still in prototype stage, but we were impressed enough to share it with you. CV Products’ XTS line is developing a new Sprint Car Cam Drive system for small-block Chevys with the raised cam that’s prominent in Sprint Car racing. The beltdrive system uses a 40mm belt to help dampen valvetrain harmonics and is said to be able to withstand engine temperatures in excess of 300 degrees Fahrenheit. The drive uses a roller thrust bearing to eliminate excessive fiddling with a bunch of shims, and rare earth magnets are used in the integrated crank trigger for accurate cylinder timing. CV’s engineers say that the system is currently being tested with a few select teams, so the design won’t be finalized until they see success on the racetrack.

FIA Approved

Most of us don’t have the means to perform our own sled testing, so there is a certain amount of trust that must be taken when purchasing a head-and-neck restraint system. That’s why we’re sharing with you that Simpson’s Safety Solutions Hybrid Pro head-and-neck restraint system has been certified by the FIA for racing. We understand that few of Circle Track’s readers will be doing any sports car racing in Europe any time soon, but its acceptance by another high level racing body is just another level of proof that the Hybrid Pro works as advertised.


Custom Crew Shirts

Custom crew shirts have been around for a while, but a company called Throttle Threads is putting a new twist on the old work shirt. First, it will help you design a logo for your race team. Once you have the look you want, it can stitch whatever you want onto patches practically any size and shape. Instead of stitching directly on the shirt, the patches are heat bonded to the shirt so you won’t get that bunching you so often see. Plus, Throttle Threads has a cool option where you can have a sleeve patch identifying each crew member, such as “Crew Chief,” “Tire Specialist,” and more.

Big Cam Iron Block

World’s new cast-iron block brings big time engine tech to an affordable cast-iron block. A big cam tunnel will accept a 50mm cam with a roller bearing or a 55mm big boy with a babbet cam bearing. The crankcase can handle a stroke of up to 4 inches and the block can be ordered with either a 9.025- or 9.075-inch deck height. The lifter bores arrived already bushed and can be sized to accept either 0.904- or 0.842-inch diameter lifters. Best of all, World doesn’t upcharge its customers for the different options.

Pro Seal Gaskets

JE’s new Pro Seal line is taking MLS gasket tech to the next level. The steel layers are all laser cut and the embossed lines that provide the critical sealing capabilities are created in a multi-step process (instead of a single stamping) to reduce stress points. JE is also using a proprietary new coating technology on the gaskets that covers all the material, not just the outer two pieces of metal.

Lightweight Connecting Rod

Molnar Technologies is a new kid on the block, but its engine components are already showing up in winning race engines. Of particular interest is its new lightweight Chevy rod which is a great option for Late Model Stock and other two-barrell classes that top out at 450 to 500 horsepower. This rod has a very narrow beam and can be ordered as light as 496 grams. Quality 3/8-inch ARP bolts are used, and lengths can be had between 5.800 and 6.250.

Legends Harness

INEX, the sanctioning body for Legends racing, has announced that it will now allow radios to be used in the Masters and Pro Legends racing classes. And right on the heels of that announcement, Racing Electronics stepped up with a custom-designed radio harness designed to suit the needs of these racers. This radio harness will adapt to all receivers, is easy to install and—along with most things in Legends racing—is designed to be affordable.

Tablet Scales

Wireless scales have been around for a while now, but Longacre has made life easier for race teams by eliminating the bulky receiver unit and replacing it with a lightweight tablet. Besides giving you your information in an easy-to-read format, Longacre has also taken advantage of the modern tablet technology for a few extra conveniences. For example, as you work your way around the car, you can spin the screen to always keep the readout oriented in the same position you are. You can quickly hide the readout if you happen to be scaling your car at the racetrack and a competitor stops by to visit. Heck, you can even download a photo of your own race car to the tablet.


The Pit Grill

How’s this for efficiency: You can go to the pit box for the 3/8-inch socket and flip the burgers at the same time? It may sound silly at first, but this has got to be one of the most interesting pit boxes ever.’s Grill Box measures 24 inches wide by 58 inches long by 60 inches tall and features a stainless steel gas grill built in. Actually, this isn’t really a box for tools, but there’s plenty of room for vittles and even a space for a cooler. The Grill Box comes in red, black, or white and is sure to be a focal point for entertaining family, friends, and—most importantly—sponsors in your pit.

Big Flow

Meet the Lil’ Bo, BLP’s newest invention. By cutting on the venturis BLP has created a 750 size carb body that can flow 1,200 cfm. Of course, there’s more to it than simply going in and hogging out a lot of material. We’re told they have to weld in a bunch of material to reshape the sides of the two big venturis to maintain proper throttle response.

Sprint Car Billet

Callies has a new high-end crankshaft specifically for Sprint Car racing engines. The crank is designed to be among the lightest on the market at just 38 pounds. Besides being cut from billet steel for maximum strength, it is also profile cut to reduce windage and has an oil-shedding finish. The flanges can be modified to your specifications and a variety of journal diameters and stroke options are available.


Insulating Blanket

Design Engineering Incorporated is an industry leader when it comes to heat protection in your race car. One of its newest products is the Titanium Pipe Shield. Instead of a wrap, this shield can be laid over a portion of a tube—like the exhaust pipe after of the collector. The insulator covers only the area of the tube you want to keep heat away from and leaves the rest uncovered so that the heat can radiate out. Meanwhile, you aren’t carrying any unnecessary weight. This can be helpful for keeping exhaust heat from cooking your transmission and fluid. The Titanium Heat Shield connects securely and easily with integrated hose clamps.
