Performance Shocks - Shock Value

Non-, Single-, And Double-Adjustables-They're In Here

0709ch_01_z Performance_shocks 2/12

At one time or another, most of us have been guilty of scheming for added power, even taking the time to hash out the aesthetics, way before ever giving thatratty old suspension a second thought. Adding fuel to the fire, we need to take into consideration that today's average small-block is easily throwing down in excess of 400 hp; truth be told, we need to come to terms with the simple fact that our beloved musclecars were never intended to be subjected to these types of extremes some 10-plus years later. That said, mingle the power with the dated, ill-handling road manners, and you've concocted a recipe for potential disaster.

While we're not going to get into the historical outline of shock absorbers, we do want to point out that all shocks are not created equal. In their simplest form, shocks are nothing more than a means to help provide a smooth ride by controlling excessive suspension movement. For a really smooth ride, a well-designed shock will allow the use of a softer spring rate, while the shock itself will control the rate at which the spring will react to bumps. Or, to put it visually, have you ever noticed a vehicle with its front wheel bouncing up and down uncontrollably, all while tracking straight? That's a worn-out set of shocks at work.

If you're only looking to exchange your vintage junkers for a factory replacement, then just about any new shock will suffice; however, if you're looking to step into the performance arena, this is where the door really opens up. The good news is, unlike yesteryear, we have a wide variety of quality shocks to choose from. Depending on your application and what you're trying to achieve, the aftermarket offers everything you need for cruising, open-track, or drag-racing applications. Going one step beyond, several manufacturers now offer their own lines of shocks with custom valving to match their suspension components. This means less guesswork on settings and easy bolt-on applications. Another viable-yet more extreme-option is getting into single-adjustable shocks that allow for additional tuning or, for the ultimate in suspension tweaking, you can go with a set of double-adjustables, which allow custom tailoring for any road and track conditions. So whether you're looking for a basic replacement to something exotic, we've listed the best of the best, and now you'll be in the know of what's out there.

Nonadjustable
Believe it or not, many prefer nonadjustable shocks over their trick counterparts, namely for the sake of simplicity. Depending on what manufacturer you opt for, nonadjustables tend to feature a wide range of valving to accommodate for various types of energy (bumps), large or small. Another advantage is the price point, which is still slightly higher than OEM replacements but generally less than adjustables.

Lakewood
If you have a strip car that sees limited street duty, Lakewood offers front 70/30 and rear 50/50 drag shocks that have excellent road manners while allowing the frontend to rise to transfer weight onto the rear tires and then to settle quickly. For more aggressive applications, Lakewood also has a 90/10 version.

Single-Adjustable & Double-Adjustable
If you're one to tinker, have a street car, and want the basic ability to stiffen or loosen the shocks as you please, then single-adjustable is the way to go. These shocks allow you to adjust the rebound and are priced significantly lower than the double-adjustable versions. But when it comes to complete tunability, double-adjustable shocks are by far rated supreme, allowing for unlimited control of both compression (bump) and rebound (extension). The biggest drawback, if you can call it that, is the incredible range of configurations they allow for. If you've only had limited experience with them, be prepared to allow for a learning curve-and expect to shell out a few Benjamins over the single-adjustables.

Air Ride Technologies
While taking advantage of the wide range of adjustability of a double-adjustable shock, Air Ride incorporates an airbag as a supporting member of the suspension as if it were a coilover spring. This air "spring" has nearly infinite adjustability of load capacity and spring rate, which translates into nearly infinite adaptability to any given road condition. Yes, that includes both the road course and dragstrip.
