The 5 Biggest Shock Buying Mistakes Builders Make

The 5 Biggest Shock Buying Mistakes Builders Make

Stop Guessing and Build a Suspension That Actually Works

Walk through any off-road event and you'll see incredible builds with thousands of dollars invested in suspension. Unfortunately, you'll also find plenty of vehicles that don't ride as well as they should—not because the shocks are bad, but because they were chosen for the wrong reasons.

One of the most common questions we get at Wide Open Design isn't, "What's your best shock?" It's "What shock should I buy?"

The answer is almost never as simple as picking a brand or buying the biggest shock you can afford.

Whether you're building a Jeep, rock crawler, trail buggy, Ultra4 car, overland rig, or rock bouncer, the best suspension starts with understanding your vehicle and how you actually plan to use it.

Let's look at the five biggest mistakes we see builders make—and how to avoid them.

Mistake #1: Buying the Same Shocks Your Buddy Runs

One of the biggest mistakes we see is builders choosing shocks because "my buddy runs them and loves them."

That's great—but his suspension was built around his vehicle, not yours.

Two rigs might both be running 40-inch tires, but a lightweight rock crawler, a trail Jeep, and a fully loaded overland rig all place completely different demands on their suspension.

The right shock depends on much more than brand name. It should match your:

  • Vehicle weight and weight distribution
  • Wheelbase and suspension geometry
  • Tire size and available wheel travel
  • Driving style—rock crawling, trail riding, overlanding, desert running, or racing

For example, your friend's 4,200-pound trail buggy may ride great on 2.5 remote reservoir coilovers. That doesn't mean the same setup will work on your 5,800-pound overland Jeep loaded with armor, camping gear, and 40-inch tires. The suspension is controlling an entirely different vehicle, so the results can be completely different.

Mistake #2: Assuming Bigger Shocks Are Always Better

It's easy to assume a 3.0-inch shock must be better than a 2.5, and a 2.5 must be better than a 2.0. In reality, bigger isn't always better—it just means the shock was designed for a different job.

Larger shock bodies offer more oil volume and better heat management, making them a great choice for heavier vehicles, high-speed driving, and long periods of hard use. But they also take up more space, weigh more, and cost more.

When choosing shock size, consider:

  • Vehicle weight – Heavier rigs typically benefit from larger shocks.
  • Driving speed – Faster vehicles generate more heat and demand more damping.
  • Available mounting space – Larger shocks aren't always the easiest to package.
  • Budget – Buy the shock that fits your needs, not just your wallet—or your ego.

For many trail rigs, Jeeps, and lightweight buggies, a 2.0 coilover can provide excellent ride quality and all the performance needed for crawling and recreational trail use. On the other hand, a heavy Ultra4 car or high-speed desert truck may benefit from the added oil capacity and cooling of a 2.5 or 3.0 shock.

Mistake #3: Focusing Only on the Shock

A great suspension system is exactly that—a system.

Even the best shocks can't make up for the wrong springs, poor mounting geometry, or missing supporting components. Every part of your suspension works together to control the vehicle, absorb impacts, and protect expensive components from damage.

A complete suspension system includes:

When one component is overlooked, the entire suspension suffers. For example, a missing limit strap can allow a shock to become the suspension's droop stop, while inadequate bump stops can force the shock to absorb hard bottom-outs—both leading to premature wear or costly failu

Mistake #4: Buying Without a Plan

One of the easiest ways to waste money on suspension is to start shopping before you have a plan.

Before you choose a shock, take a step back and think about how your vehicle will actually be used.

Ask yourself:

  • What type of terrain will I drive most?
  • Will I be rock crawling, trail riding, overlanding, or driving at higher speeds?
  • How much suspension travel am I planning?
  • What's my realistic budget?
  • Are larger tires or future upgrades planned?
  • How much does my vehicle weigh when it's trail-ready?
  • Will I regularly carry passengers, gear, or camping equipment?

Answering these questions first makes every suspension decision easier—from choosing the right shock body size to selecting springs, bump stops, and supporting components.

That's exactly why we built the Wide Open Design Shock Selection Guide. Instead of guessing, the guide walks you through these questions and recommends the suspension setup that best fits your vehicle, driving style, and performance goals.

Mistake #5: Thinking Shocks Never Need Service

Quality off-road shocks are built to last—but they aren't maintenance-free.

Every mile on the trail creates heat. Over time, the shock oil breaks down, seals wear, nitrogen pressure changes, and moving components experience normal wear. The harder you use your vehicle, the more important regular inspection and maintenance become.

A quick inspection before and after a trip can help catch small issues before they become expensive repairs.

Look for:

  • Oil leaks around the shaft or seal head
  • Bent or damaged shock shafts
  • Worn rod ends or mounting hardware
  • Loose fasteners
  • Damaged reservoirs or hoses
  • Excessive corrosion or physical damage
  • If your shocks no longer ride like they used to, feel harsh, bottom out more easily, or show visible signs of wear, it may be time for a rebuild or service.

Final Thoughts

Choosing the right shocks isn't about buying the biggest body, the most expensive option, or the brand someone else recommends.

The best suspension is the one that's designed around your vehicle, your terrain, and the way you drive. When your shocks, springs, mounts, bump stops, and supporting components are engineered to work together, you'll end up with a vehicle that's more capable, more predictable, and more enjoyable to drive.

Whether you're building a weekend trail Jeep, a rock crawler, an overland rig, or a competition rock bouncer, taking the time to plan your suspension before you start buying parts will almost always save you money—and lead to a better-performing vehicle.

If you're ready to build with confidence, start with our Shock Selection Guide. It's designed to simplify the process, explain your options, and help you choose a suspension system that fits your build from the ground up.
