N90 Hilux Suspension Bushes and Leaf Spring Kits

Worn suspension bushes let the N90 Hilux feel loose, clunk and wear tyres, and polyurethane replacements last longer than factory rubber. Fulcrum stocks SuperPro and Whiteline bush kits plus heavy duty leaf spring bush and greasable shackle kits for the N90, fitted for you. Check out of our full guide to N90 Hilux suspension.

Bushes are the quiet part of the suspension that most owners forget until the ute starts to clunk and wander. On the N90 Hilux the control arm, leaf spring and shackle bushes take a hammering off road and under load, and the factory rubber softens and cracks over time. Replacing tired bushes, especially with polyurethane, brings back tight, predictable handling and stops the rear feeling loose.

How do I know my Hilux bushes are worn?

The tells are a clunk over bumps, a rear that feels loose or vague under load, steering that wanders, and uneven or accelerated tyre wear. Visually, worn rubber bushes crack, perish or squash out of shape. Off road use and load carrying speed this up, because the bushes work harder and hotter than they do on a road only ute. If your N90 has covered serious dirt or carried weight, the bushes are often the cheapest fix that makes the biggest difference to how tight the ute feels.

The takeaway: clunks, a loose rear, wandering steering and uneven tyre wear all point to worn bushes worth replacing.

Polyurethane or rubber, which is the better upgrade?

Polyurethane is the better upgrade for a working N90. Factory rubber is soft and quiet when new, but it deflects under load and perishes with heat, oil and age, which is why the ute loosens up over time. Polyurethane holds its shape under load, resists oil and heat, and lasts far longer, so the suspension geometry stays where it should and the handling stays tight. The old objection was noise, but modern poly bushes are designed to run quiet when fitted and greased correctly. For a ute that works or tours, poly is the upgrade that keeps it feeling tight for longer.

The takeaway: polyurethane outlasts and outperforms rubber for a loaded or off road N90, and modern poly runs quiet when fitted properly.

Do bushes need doing with a lift or GVM upgrade?

It is the ideal time. When the suspension is apart for a lift, GVM upgrade or shock replacement, refreshing the bushes and leaf spring hardware costs little extra labour and sets the whole rear and front up fresh. Alignment correction bushes also help bring caster and camber back after a lift, which protects your tyres. Doing bushes as part of a bigger job avoids paying twice for the same strip down.

The takeaway: fit fresh bushes and leaf spring hardware while the suspension is apart for a lift or GVM upgrade, and save the double labour.

The takeaway: match the kit to the worn area, and poly holds its shape where rubber gives way.
