If you've clocked over 80,000 kilometres in your 4WD, chances are your shock absorbers are no longer performing as they should. Whether you're tackling rugged off-road terrain or cruising through city streets, your shocks play a vital role in your vehicle's handling, ride quality, and durability. In this blog, we’ll cover why upgrading your shocks is essential and how Formula 4x4 Big Bore Shocks can take your driving experience to the next level.
Why Do 4x4 Shock Absorbers Wear Out?
Standard OEM shock absorbers are designed for everyday driving, not the harsh conditions of off-road adventures. Over time, the oil inside these sealed units breaks down, reducing their ability to absorb impact forces. Unlike engine oil, which can be replaced regularly, shocks must be entirely replaced once they wear out.
If your shocks have surpassed 80,000 kilometres, you might notice:
- Reduced handling and responsiveness
- A rougher, less comfortable ride
- Increased vehicle sway and body roll
Ignoring worn-out shocks not only affects your 4x4’s ride comfort but also compromises its safety, making it harder to maintain control over extreme terrain.
Why Upgrade to Formula 4x4 Big Bore Shocks?
When it comes to off-road performance suspension, not all shocks are created equal. Formula 4x4 Big Bore Shocks are specifically engineered to handle the demands of lifted vehicles, increased load-carrying capacity, and extreme driving conditions.
Here’s what sets them apart:
1. Larger Pistons for Improved Impact Distribution
The larger bore and piston diameter of Big Bore Shocks allow for better distribution of impact forces. Assuming a force of 1,000 newtons is applied across a standard and Big Bore shock - compared to a standard shock with 30mm pistons, Big Bore shocks 40mm pistons reduce pressure from 1.41 to just 0.8 newtons per square millimetre, that’s almost half the pressure! This reduction means less stress on internal components, resulting in enhanced durability and a smoother ride.
2. Increased Oil Capacity & Heat Dissipation
With a 70mm outer tube and 58mm strut diameter, Big Bore Shocks offer increased oil capacity, which helps dissipate heat more effectively. This design is crucial for maintaining consistent performance during prolonged use on corrugated roads and rough trails.
3. High-Temperature Seals & Fuchs Oil
These 4WD shocks use high-temperature seals and premium Fuchs oil to ensure optimal performance even in the harshest environments. This combination prevents shock fade, allowing your 4x4 to maintain control and comfort in demanding conditions.
4. Built to Last with SuperPro Bushings
Equipped with SuperPro bushings, these shocks deliver exceptional durability and improved suspension performance. The heavy-duty design ensures that the shocks can withstand repeated impacts without degradation, making them ideal for off-roading and outdoor adventures.
The Benefits of Upgrading Your 4WD Shocks
Upgrading to Formula 4x4 Big Bore Shocks provides numerous benefits, including:
✅ Enhanced handling and stability on all terrains
✅ Smoother, more comfortable ride
✅ Improved load-carrying capacity
✅ Reduced wear and tear on suspension components
✅ Longer lifespan and reliability in harsh conditions
Perfect for Suspension Lifts & Heavy Loads
If you've modified your 4WD with heavier springs, bar work, winches, or a suspension lift kit, standard shocks may struggle to control the increased load and vehicle height. Big Bore Shocks are available in various lengths to accommodate suspension lifts, ensuring optimal performance and extended travel without overextending the shocks.
