HSD Dualtech Coilovers Nissan Cefiro A31 88-94

HSD Dualtech Coilovers for Nissan Cefiro A31 (88-94) – 14-Way Twin-Tube Damping, Height & Camber Adjustable

The HSD Dualtech kit replaces the worn or soft factory dampers on your Nissan Cefiro A31 with four fully adjustable twin-tube coilovers built specifically for this car. It is HSD's road-focused range: a big step up in body control and steering response over standard suspension, while keeping a ride you can live with every day and the option of the odd track day.

The 14-way damping adjuster lets you go from a softer road setting to a firmer track setting in a few clicks. Ride height is set by screwing the damper body up or down, separately from spring preload, so you can lower the car without losing suspension travel or changing how the spring behaves. Front camber is adjustable, which helps you get the most from your tyres once the car is lowered.

Installation

The kit is a direct replacement for the standard dampers and springs on the Nissan Cefiro A31, using the factory mounting points with no cutting or drilling. Set an even ride height side to side using the body adjustment rather than the preload collars, tighten every lock ring, then have a full four-wheel alignment done, including camber. Check the ride height and that all bolts and lock rings are tight again after the first few hundred miles. We recommend professional fitting by a garage with spring compressors and alignment equipment.

Can I get different spring rates?

This kit comes with 7kg front and 5kg rear springs. HSD springs are available in a wide range of rates, so contact us if you need a custom set-up for track use.

Does this kit fit my car?

HSD lists this kit for the Nissan Cefiro A31 (1988-1994). Not suitable for: any model not listed above.

Can I adjust camber with these coilovers?

Yes. Front camber is adjustable. A full alignment is still needed after fitting.

What is the difference between HSD Dualtech and MonoPro?

Dualtech uses 14-way twin-tube dampers and is aimed at road cars with occasional track use. MonoPro uses 16-way high gas-pressure monotube dampers that stay consistent when driven hard, and suits regular track days.

Can I lower the car without changing the spring preload?

Yes. HSD coilovers adjust ride height by screwing the damper body in its lower mount, separately from the spring preload collar, so you keep the same spring behaviour and damper travel.

Do I need a wheel alignment after fitting?

Yes. Changing ride height alters toe and camber, so a full four-wheel alignment is needed after fitting and after any big height change.

Are these coilovers road legal?

Yes, they are designed for road use. Lowering is a modification, so tell your insurer, and keep enough ground clearance and suspension travel for UK roads.

What warranty do HSD coilovers have?

HSD coilovers are covered by a 12-month warranty against defects in materials and workmanship. Spare parts, springs and rebuild support are available through the UK distributor.
