FORMULA Leaf Springs with Fitting Position Rear Axle for Vehicle

The Importance of U-Bolts

• Seized or Broken U-Bolts: Old U-bolts often seize or break, requiring cutting for removal.
• Damaged Threads: Removing old U-bolts can damage threads, leading to loose U-bolts and voided warranties.
• Incorrect Length: Stronger leaf springs may need longer U-bolts.

• Shape: Square, round, or semi-round.
• Material Size: Measure the rod's diameter at the thread.
• Inside Measurement: Ensure it fits over the differential or spring pack.
• Leg Length: Measure from the underside of the top to the leg end.
• Thread Length: Ensure enough thread for secure fastening.
• Material Grade: Use high-grade materials for durability.

• Re-tension: Re-tighten U-bolts 7-10 days after installation to secure the springs.
• Correct Fit: Ensure U-bolts match your vehicle's specifications.

Introducing Formula 4x4's Parabolic Leaf Springs for 4WD vehicles. Designed to revolutionise traditional leaf spring systems, these innovative springs offer:

• Comfortable Ride: Utilising modern technology and a tapered "parabolic" design, Formula 4x4's Parabolic Leaf Springs provide a smoother and quieter ride compared to traditional heavy leaf packs.
• Enhanced Flexibility: With fewer leafs and independent action, these springs adapt to varying loads and terrain conditions, ensuring all four wheels stay grounded for maximum traction and safety.
• Reduced Weight: Made from special grade steel and featuring a tapered design, these springs dramatically reduce unsprung weight, improving handling and comfort both loaded and unloaded.
• Superior Strength: Despite their lighter weight, Parabolic Leaf Springs maintain exceptional load carrying capability, providing durability and performance in challenging off-road conditions.
• Minimised Friction: The unique design minimises interleaf friction, reducing noise and helping to prevent rust buildup for long-lasting performance.
• Enhanced Safety: By absorbing shocks more effectively, these springs minimise stress on differential gears, ensuring smoother rides and reducing the risk of wheel spin in rough terrain.

Upgrade your 4WD experience with Formula 4x4's Parabolic Leaf Springs - combining innovation, comfort and reliability for all your off-road adventures.
