[Heavy Duty] Leaf Spring Automotive Suspension Modification Kits

High-performance leaf spring suspension kits engineered for trailers and light trucks. Each kit balances load capacity (500kg–1500kg) with modular components — springs, U-bolts, shackles, bushings, and plates — ensuring durability, stability, and shock absorption across diverse road conditions.

Trailer suspension kits (300–1500 kg) with 4–7 leaf springs, lengths 52–64 cm, engineered for durability, stability, and optimized load performance

Features

Load-Specific Design - Kits are available in 500kg, 800kg, and 1500kg ratings, tailored for precise payload requirements.

Multi-Leaf Spring Engineering - Layered steel leaves distribute stress evenly, reducing wear and enhancing ride comfort.

Shock Dampening  - Shackles and bushings absorb vibration, protecting cargo and extending chassis life.

Secure Mounting Hardware - Heavy-duty U-bolts, brackets, and plates ensure rigid installation with minimal flex.

Modular Replacement - Components are interchangeable, enabling quick upgrades or repairs without full system overhaul.

Corrosion Resistance - Reinforced steel and treated hardware extend service life under heavy-duty use.
