Used Nissan Interstar Coil Spring

No — the Nissan Interstar (sold in the UK roughly 2002–2010, and based on the Renault Master / Opel Movano platform) uses a torsion bar suspension at the front and leaf springs at the rear on all variants; coil springs were not fitted to any version of this van. If you are hearing a knocking or sagging at the front, you are most likely looking for a torsion bar, anti-roll bar drop link, or front shock absorber rather than a coil spring. Speak to a breaker with your registration to confirm which suspension component you actually need.

Almost certainly yes — the Interstar does not use coil springs on any axle, so any listing for a coil spring on this model is likely a cataloguing error or a confusion with a different vehicle. The front suspension relies on torsion bars and the rear on leaf springs, so please double-check the part description and ask the breaker to confirm the correct component against your registration number. You may be looking for a torsion bar adjuster, a leaf spring, or a shock absorber instead.

For the front axle you need to look at torsion bars, front shock absorbers, anti-roll bar links, and wishbones (upper and lower); for the rear axle the key components are leaf springs, rear shock absorbers, and spring hangers or shackles. Because the Interstar was offered in different payload and GVW ratings, the correct torsion bar or leaf spring specification can vary, so always give the breaker your registration and check the vehicle identification plate for the GVW rating rather than relying on the model name alone. A breaker who specialises in Renault Master or Opel Movano parts will often be able to help, as these three vans share the same basic platform and suspension layout.

Quite possibly, as the Interstar, Renault Master (Mk2), and Vauxhall/Opel Movano of the same generation share a common platform and many suspension components are interchangeable across the three. However, GVW and payload variants can mean different spring rates and component specs even within the same platform, so you must confirm the exact part number against your vehicle's VIN and GVW plate before buying. Route this cross-brand compatibility question to the breaker with your registration, and they can check the part numbers directly.

Engine size can influence front torsion bar and shock absorber specification, since heavier or more powerful engines add load to the front axle, so it is worth telling the breaker which engine you have. Trim level and colour make no difference to the suspension specification on the Interstar. The most important factor is the GVW or payload rating shown on the vehicle's plate inside the door shut, as higher-rated vans were built with heavier-duty suspension components.
