Throwback Thursday: A New CPP Spindle Updates Classic Suspensions

I hope you’re ready for the end of the week as another Thursday is already here. That means Friday is about to land on our garage door, and it’s time for another Throwback Thursday.

This week, we are taking a short trip back to June 2018, to check out, CPP Updates Classic Suspensions With An All-New Spindle Design. Suspension upgrades have been done for years, and when Classic Performance Products (CPP) – a company that has a firm grasp on building suspension parts that improve vehicle handling – introduced a new component to its suspension line, we took notice.

The spindle works with factory C5, C6, and C7 Corvette hub/bearing pack, rotors, and calipers.

“With trends heading toward the Pro Touring market, the use of sealed-bearing hubs simply makes sense for use on a road course or for all-out performance applications,” stated Aaron Strietzel senior tech guy at CPP. “With our new CS spindles, we bring the performance of the maintenance-free hub design that is used on late-model Corvette applications (C5/C6/C7), and the usability of popular 13 and 14-inch disc-brake kits. These purpose-built spindles are available for all A, F, and X-body applications.”

In the original article, we discuss how — with the sealed-bearing hub assembly — you no longer need to continually grease and inspect bearings depending on how hard you push your car’s suspension. Since the assembly uses a Corvette hub, that also means any stock or aftermarket Corvette disc-brake kit will fit. However, you are limited by wheel size. The Corvette has a huge performance-brake pad selection, and you can find replacement parts on the shelf in almost any parts store. That’s a huge benefit when it comes time for maintenance.

The ’67 through ’69 Camaro, ’64 through ’72 Chevelle, and ’68 through ’74 Nova applications feature a raised upper ball-joint location. The other CPP spindles retain the original geometry. Doing this keeps them compatible with all of your existing steering and suspension components.

The CPP (PN: CP30013) spindle features a raised upper ball-joint mount to yield a better camber change during suspension movement. They also utilize factory bolt-in or CPP-replacement steering arms.

“The spindle is cross-compatible with just about any product that is designed for use with the original-spindle geometry. You can even utilize a tall upper ball-joint if you want,” Engineer Danny Nix stated. “Adding a taller-than-stock ball joint can increase negative camber-gain when cornering, which helps keep the tires flat on the pavement, greatly improving handling characteristics. If you want to make any other changes to your steering or suspension, you can consider the CS spindle to be the same geometry as the OE spindle.”

The article actually gets into the nitty-gritty of the benefits and installation, and suffice to say, there is much more in-depth insight highlighted in this informative article. That definitely makes it worthy of a second look. For that reason, I selected CPP Updates Classic Suspensions With An All-New Spindle Design as this week’s Throwback Thursday showcase article.
