Spacer Lift Kits Are a Bad Idea — Here's What Mesa AZ Truck Owners Should Do Instead

If you've been shopping for a lift kit and stumbled across spacer lifts because of their low price tag, stop right there. Spacer lift kit problems are real, they're expensive, and they can make your truck genuinely dangerous to drive. At Underdog Motorsports in Mesa AZ, we see the aftermath of cheap spacer lifts on a regular basis — worn-out ball joints, blown CV axles, destroyed tire wear patterns, and suspension geometry so far off that the truck handles like a shopping cart. This post is going to tell you exactly why spacer lifts are a bad idea and what a real suspension upgrade actually looks like.

What Is a Spacer Lift Kit, Exactly?

A spacer lift kit does exactly what it sounds like — it stacks a chunk of aluminum or polyurethane on top of your factory strut or coil spring to push the suspension down and create the appearance of lift. That's it. No new shocks. No revalved dampers. No corrected geometry. Just a spacer forcing your suspension into a range it was never designed to operate in.

They're cheap, they ship in a box, and they look like a quick win. They are not a quick win. They are a ticking clock on your suspension components.

Spacer Lift Kit Problems You Need to Know About

1. Destroyed CV Axle Angles

Your factory CV axles are engineered to operate within a specific range of motion. When you slam a spacer on top of the strut and drop the lower control arm without correcting geometry, you're forcing those axles to operate at extreme angles they were never built for. The result? Premature CV axle failure, clicking at low speeds, and eventually a blown axle on the trail or the highway. If you're running your Tacoma or 4Runner out to Bulldog Canyon or down the Apache Trail, a failed CV axle is more than an inconvenience — it's a rescue call.

2. Accelerated Ball Joint and Tie Rod Wear

Spacer lifts push your suspension geometry out of spec. That means your ball joints and tie rods are now working at angles that accelerate wear dramatically. We've seen trucks come into Underdog Motorsports near Chandler and Gilbert with ball joints worn to failure at 20,000 miles because of a spacer lift installed a year earlier. Factory ball joints are not designed for the stress load a spacer lift creates. And when a ball joint fails, your wheel doesn't just wobble — it separates. That's a catastrophic failure at any speed.

3. Terrible On-Road Handling

Spacer lifts don't fix your suspension — they just stress it in new directions. Your caster angle, camber, and toe are all affected when you lift a vehicle without correcting for it. The result is a truck that wanders on the highway, eats through tires unevenly, and feels unstable in corners. The same truck that felt planted at highway speeds now feels vague and twitchy. That's not a trade-off you should be making.

4. No Improvement in Suspension Performance

Here's the part that really gets us: a spacer lift doesn't make your suspension better. Your factory shocks are still there, still tuned for stock ride height, now operating outside their designed range. You get more wheel gap, but you don't get more travel, better damping, improved off-road capability, or any of the actual benefits that come from a real suspension upgrade. You're paying money to make your truck worse in every measurable way except aesthetics — and even then, the stance is usually off because geometry isn't corrected.

What a Real Lift Kit Actually Does

A properly engineered lift kit — from brands like ICON, Fox, Bilstein, Carli, BDS, King, Eibach, or Old Man Emu — is designed from the ground up to lift your specific vehicle while correcting for the geometry changes that come with that lift. These systems include revalved shocks or coilovers tuned for your vehicle's weight and intended use, extended upper control arms to correct caster and CV angles, alignment-corrected components, and in many cases improved bump stop and droop travel that makes your truck genuinely more capable both on and off road.

An ICON Stage 2 system for a Tacoma isn't just taller than stock — it's better than stock in every performance metric. Same goes for a Fox 2.5 coilover setup on a 4Runner or a Carli system on a Ram. These kits are engineered. Spacers are not.

If you're looking for the best lift kit shop in Mesa AZ, Underdog Motorsports at 1845 S Power Rd specializes in professional suspension upgrades for Toyota, Jeep, Ford, Ram, and GM vehicles — and we'll help you find the right system for your budget and your use case without cutting corners.

Why Professional Installation Is Non-Negotiable

Even the best lift kit in the world can be compromised by a bad install. Suspension work involves torque specs, alignment procedures, component sequencing, and geometry correction that require the right equipment and experience. A proper lift kit install at Underdog Motorsports near Scottsdale and Tempe includes a full alignment after installation, correct torque on every fastener, and a team that has installed these exact systems on these exact vehicles dozens or hundreds of times.

DIY installs and shade-tree shops that slap on parts without an alignment rack or the right knowledge are almost as bad as the spacer lifts themselves. The "buy once, cry once" philosophy applies to both the parts and the installation. Do it right the first time and you won't be back in six months replacing ball joints, CV axles, and tires.

The Bottom Line on Spacer Lifts

Spacer lifts are cheap for a reason. They don't engineer around your vehicle's geometry — they fight it. The long-term cost in worn suspension components, destroyed tires, and compromised safety far exceeds whatever you saved up front. If you want real lift, real capability, and real peace of mind, invest in a proper suspension system from a brand with engineering behind it and have it installed by professionals who do this every day.

Frequently Asked Questions

Are spacer lift kits safe for daily driving in Mesa AZ?

No. Spacer lifts force your suspension geometry out of spec, accelerating wear on ball joints, CV axles, and tie rods. The handling degradation and risk of component failure make spacer lifts a poor choice for any vehicle — daily driver or weekend wheeler. A proper lift kit from ICON, Fox, Bilstein, or BDS corrects for these issues where a spacer never can.

How much does a real lift kit cost compared to a spacer lift?

A quality entry-level lift system from brands like Eibach or Old Man Emu starts in the $800–$1,500 range installed. Mid-tier systems from ICON or Fox run $2,000–$4,000 installed depending on the vehicle. Spacer kits might cost $150–$400, but when you add in the ball joints, CV axles, and tires you'll be replacing early, you've already spent more than a real lift kit would have cost. Buy once, cry once.

What lift kit does Underdog Motorsports recommend for a Toyota Tacoma or 4Runner?

It depends on your use case, but for most Tacoma and 4Runner owners in the Mesa and East Valley area, we recommend ICON Stage 2 or Stage 3 systems, Fox 2.5 coilovers, or Old Man Emu BP-51 setups for a trail-ready build that still drives great on the street. Every recommendation is specific to your trim level, tire size goals, and how you use the truck. Call us at 480-269-2833 and we'll walk you through it.
