Engineered to win. Here's how the program works.

The car, the system, and the driver — when all three work together, that's when teams find consistent speed.

Step 1
The Hardware

We consult on your driving style, chassis, weak points, and tracks — then spec the right platform: Bilstein or Genesis — both by Martin Dynamics, matched to your class, rules, and budget.

  • Full custom-valved shock set — dyno-tested and matched as a system
  • Factory-authorized Bilstein sales & service, in-house
  • Matched Hyperco spring package, fully set and ready to install
  • Coil-over kits and all hardware
  • Bump stops, packers, washers, and bearing kits
Step 2
The System

Fast teams don't make random adjustments — they follow a system. We give you the tools to build and maintain yours.

  • Comprehensive setup manual — car, shocks, springs, and when to adjust
  • Online training course covering the whole process
  • Baseline setup sheets by track condition + blank sheets for every race night
  • Shock & bump stop maintenance tool kit in a heavy-duty case
Step 3
The Driver

The biggest variable in the race car is the driver. Most teams spend hours on the car and none on the driver — this changes that.

  • GoPro with chassis mount and carrying case
  • Step-by-step film upload process
  • One-on-one film review — line choice, entry, throttle
  • Setup evolves with the driver through the season

The hardware, up close

Every shock is built, valved, and dyno-tested in-house in Waterford, PA — then matched as a set to your car.

Sound like what your program is missing?

From the guy who valves your shocks

Dear Driver,

If you're like most of the teams that call me, you've already spent good money on shocks. Maybe you bought what the fast guy runs. Maybe you sent them out for a revalve and got back a dyno sheet nobody ever taught you to read.

And on Saturday night, when the track goes slick, you're still guessing.

Here's what I've learned building shock packages for more than 125 teams: it's almost never that your shocks are junk. It's that nobody engineered them for your car, your tracks, and your driving style — and nobody stuck around to help you adjust when conditions changed.

That's why this is a program, not a parts order. We start with your car and your goals. We engineer the package around them — on a Bilstein or Genesis platform, custom-valved and dyno-proven. Then we hand you the system to run it and stay in your corner all season. When something doesn't make sense on race night, you call, and the engineer who valved your shocks answers.

You don't need more parts. You need a plan — and an engineer in your corner.

Let's build yours.

Mechanical Engineer · Founder, Martin Dynamics

Is this program right for you?

This is for you if…
  • You race weekly and you're done guessing on shocks and springs
  • You want one accountable expert — not a parts counter
  • You'll follow a system and write down your setups
  • You're willing to work on the driver, not just the car
This is not for you if…
  • You're shopping for the cheapest set of shocks on the internet
  • You want a magic bullet without changing how you work
  • You'd rather collect setup tricks than follow a process
  • You're not planning to run a full season

"We switched over to a different shock program last week. I'm really happy with the way the season is going — I think big things are coming."

Questions racers ask

What does a package cost?

Every package is scoped on your call, because the right answer depends on your class, your rules, and your goals. This is a premium program — the hardware, the system, and a season of support — and we build options at more than one budget, from our Genesis-platform packages up to the full Bilstein triple-adjustable canister package. You'll leave the call knowing the exact number.

Will it work with my chassis?

Yes. The design starts from your chassis, motion ratios, weight distribution, and driving style — that's the whole point of custom. We've built packages for all of the major chassis brands.

I already have shocks. Can you work with them?

In many cases, yes. We service and revalve in-house, and we're factory-authorized for Bilstein service. Book the call and we'll figure out the fastest path with what you already own.

What classes do you work with?

Dirt Late Models, Dirt Modifieds, and Pro Stocks are our core — and every package is built legal to your rules.

How long until my package is ready?

Every shock is built and dyno-tested in-house in Waterford, PA. Lead time depends on the time of season — you'll get a real date on your call.

What happens on the call?

Fifteen minutes: your car, your goals, and where your current package is giving up time. You'll leave with a clear recommendation and exact pricing — whether or not we end up working together.
