Parts for your 2004 Toyota Hiace-Coil springs

2004 Toyota HiAce coil springs — are they actually used?

For anyone hunting down 2004 Toyota HiAce coil-springs, here’s the straight answer: on Australian and New Zealand–spec 2004 HiAce models (the outgoing H100 series), coil springs aren’t used. Factory technical specs and workshop manual data for the H100 list an independent front suspension with double wishbones and torsion bars, plus a live rear axle with semi-elliptic leaf springs. No coil springs are shown for either end. The rear leaf packs carry the load, while the torsion bars handle front springing.

Why no coil-springs on this HiAce? Toyota built the H100 to work hard. Torsion bars up front package neatly along the chassis rails, offer easy ride-height adjustment, and cop abuse well over big kilometres. Out back, leaf springs are the go-to for payload, stability, and durability in a van that spends its life hauling gear. It’s a tough, low-fuss setup that suits tradies and couriers alike.

A quick note on build dates: the next-gen HiAce (H200) arrived late 2004/early 2005 in many markets and moved to a different front layout. Some H200 variants use coil springs in the front suspension. If your vehicle was first registered around 2005 or you’re unsure, check the VIN/build plate and front-end hardware before ordering parts.

• Classic H100 front: look for a long torsion bar running back from the lower control arm to an adjuster on the crossmember.
• Rear: multi-leaf spring packs with U-bolts around a solid axle.
• If you don’t see front torsion bars, you may have an early H200, which can use front coil springs.

Chasing a suspension refresh on a 2004 HiAce? The usual shopping list includes front shock absorbers, upper/lower control arm bushes, ball joints, sway-bar links and bushes, torsion-bar anchors/adjusters, plus rear leaf springs, shackles, bushes, U-bolts, and rear shocks. If ride height has sagged, a workshop can reset or replace leaf packs and re-index the front torsion bars to restore trim height, then finish with a wheel alignment.

FAQs

Does a 2004 Toyota HiAce have coil-springs?
No. The 2004 AU/NZ HiAce (H100) uses front torsion bars and rear leaf springs. If yours is a late-2004 build transitioning to the H200 shape, check the VIN and front suspension layout, as some H200 variants use front coils.

What should be serviced instead of coil-springs on a 2004 HiAce?
Focus on front shocks, control arm bushes, ball joints, sway-bar links, torsion-bar mounts/adjusters, and rear leaf packs with shackles, bushes, U-bolts, and shocks. Restoring ride height and replacing worn bushes often transforms ride and steering feel.

Can a 2004 HiAce be converted to coil-springs?
Coil conversions exist in niche motorsport or custom setups, but they’re uncommon for work vans. Any conversion would need custom engineering, certification, and careful tuning. For most owners, refreshing the torsion/leaf system is the smarter, cost-effective move.
