Suspension Shock Absorber Guide for the 1979-1987 Mazda B2000
Get your classic Mazda B2000's ride and handling back in shape by choosing the right replacement shocks.
- Aftermarket shocks are the only viable option and offer modern technology that improves on the original 1980s design.
- Choose your replacement shocks based on how you use your truck: standard for daily driving, heavy-duty for work, or specialty shocks for lowered trucks.
- Brands like KYB and Monroe offer a great balance of quality and value for restoring the original ride.
- Always replace shocks in pairs (front or rear) to maintain vehicle stability and prevent unpredictable handling.
Is Your B2000's Ride Bouncy or Unstable?
As shock absorbers wear out, your truck's handling will get worse. Worn shocks can't control the suspension, leading to a ride that feels bouncy and less safe. Because this happens slowly over time, you might not notice how bad it has become. Knowing the signs of failure is the first step to getting your truck's performance back.
Common Symptoms of Failing Shocks:
🎬 Watch: A visual guide to signs of bad shocks.- Bouncy Ride: The truck continues to bounce up and down long after hitting a bump.
- Nose-Diving: The front end of the truck dips down hard when you brake.
- Body Roll: The truck leans or sways excessively on turns and lane changes.
- Rear Squat: The back of the truck drops down when you accelerate.
- Visible Leaks: You can see oil or fluid on the outside of the shock absorber body.
- Uneven Tire Wear: Your tires have bald spots or a wavy, cupped wear pattern.
OEM Parts Are No Longer an Option
For a vehicle as old as the 1979-1987 B2000, original Mazda shocks are no longer available. The good news is that modern aftermarket shocks from reputable brands often use technology that is superior to what was available in the 1980s, offering a significant upgrade in performance and durability.
Choosing the Right Aftermarket Shocks
With many brands available, you should choose a shock that matches how you use your truck. Shocks are sold for different purposes, from daily driving to heavy-duty use.
Brand Tiers for Your Mazda B2000:
- Standard Replacement (Good): Brands like FCS and PRT offer an affordable way to replace old, worn-out shocks and restore basic factory handling. They are a good choice for a truck that sees light, everyday use.
- OEM-Quality (Better): KYB and Monroe are well-respected brands that provide quality and performance similar to or better than the original parts. The KYB Excel-G and Monroe OESpectrum are popular choices for restoring the original ride and control. For a stock-height truck used for daily driving, these are excellent options.
- Heavy-Duty / Performance (Best): For trucks that are used for hauling, towing, or off-road driving, brands like Rancho, Pro Comp, Skyjacker, and Superlift offer more robust options. The Rancho RS5000X, for example, is a popular twin-tube gas shock that improves handling for light trucks.
- Specialty (Lowering): If you have lowered your B2000, you need shorter shocks. Bell Tech specializes in suspension components for lowered trucks and provides shocks designed for that specific purpose.
| Component | Estimated Cost |
|---|---|
| New Aftermarket Shocks (per pair) | $45 - $200 |

Frequently Asked Questions
Do I need special shocks if I lowered my B2000?
Yes. If you have lowered your truck, you must use shocks designed for a lowered vehicle. Stock-length shocks will not have enough travel and will bottom out, leading to a harsh ride and potential damage. Brands like Bell Tech specialize in shocks for lowered applications.
🎬 See how to lower your B-Series truck the right way.What's the difference between gas and hydraulic shocks?
Gas shocks, which are the modern standard, are filled with hydraulic fluid and pressurized nitrogen gas. The gas prevents the fluid from foaming, providing more consistent performance, especially on rough roads. Most quality replacements for your B2000, like those from KYB and Monroe, will be gas-charged.
Can I replace the shocks myself?
Yes, replacing the shocks on a 1979-1987 B2000 is a straightforward job for a DIY mechanic with basic tools. The front and rear shocks are typically held in place by two bolts each. The biggest challenge is often dealing with rust on the bolts of an older vehicle. Using penetrating oil beforehand is highly recommended.
