NOLATHANE Leaf Spring Bushing

Why Nolathane Leaf Spring Bushings Stand Apart

Leaf spring bushings are among the hardest-working components in any truck, SUV, or 4WD suspension system. They absorb constant flex, bear heavy loads, and endure relentless exposure to road grime, oil, and the elements — and factory rubber simply wasn't built to last under those demands. That's where Nolathane earns its reputation. With over 50 years as the number-one replacement bushing brand in Australia and New Zealand, Nolathane has brought its proven polyurethane technology to the North American market, and their leaf spring bushing lineup is a prime example of why enthusiasts and mechanics trust them.

Polyurethane Built for Heavy-Duty Demands

The fundamental difference between Nolathane and a stock rubber replacement comes down to material science. Unlike rubber bushings, which deteriorate, dry rot, or soften with time and mileage, Nolathane's polyurethane formulations are engineered to resist wear, oil, grease, ozone, UV weathering, and heat — delivering what the brand describes as "better-than-new performance for the life of your vehicle." For trucks and 4WDs that regularly tow, haul heavy loads, or tackle off-road terrain, this durability advantage is critical.

Nolathane also takes a thoughtful approach to hardness. Rather than defaulting to a stiff racing compound, their engineers select the appropriate durometer for each specific application — most products fall in the 74 or 85 Shore A range — striking the right balance between load control and ride comfort. The result is a bushing that behaves predictably without introducing harsh NVH (noise, vibration, and harshness) into the cabin.

Leaf Spring Bushing Kits: Complete Coverage

Nolathane offers several distinct leaf spring bushing solutions to cover a variety of service needs:

• Essential Kits (NEK): An economical all-in-one service kit including front eye, rear eye, and shackle bushings — everything needed to fully service a rear leaf spring suspension in a single purchase.
• Rear Leaf Spring & Shackle Bushing Kits: Targeted kits designed specifically for rear leaf spring and shackle service, covering both standard and 4WD applications.
• 4WD-Specific Kits: Purpose-built for four-wheel-drive platforms with common frame shackles, offering the high load-bearing capability that trucks and off-road rigs demand.
• Urethane Bulk Packs: For fleet operators or shops servicing multiple vehicles, Nolathane's bulk pack format provides the same high-quality polyurethane in a cost-effective quantity format.

Mechanically Fitted, Grease-Included

Unlike OEM rubber bushings that are compression-bonded and restrict suspension pivot travel, Nolathane polyurethane bushings are mechanically fitted with minimal crush of the urethane material. The center pin is lubricated so the spring eye freely pivots without restriction — maintaining consistent alignment geometry and reducing deflection under load. Kits include a specially formulated molybdenum disulphide-based grease, engineered specifically for polyurethane pivot points, ensuring long service life right from the initial install.

The payoff is tangible: more consistent suspension geometry, improved and even tire wear, and greater predictability whether navigating city streets or crawling over rough terrain. Backed by a limited lifetime warranty, Nolathane's leaf spring bushings are a true fix-it-once upgrade for any leaf-sprung vehicle.
