Land Cruiser 300 is a large body-on-frame vehicle (5m long, 1.95m tall). Factory soundproofing is mid-tier here, less serious than premium sedans: a frame transmits less acoustic isolation than a monocoque. Above 100 km/h tire roar (especially with off-road tires) becomes audible, above 130 — aero noise from wide mirrors. Common complaint: "drum" effect from rain on roof — that's the headliner soundproofing job. Here are the options and prices.
Soundproofing tiers
Tier | Included | Price, ₽ | Effect |
|---|---|---|---|
Basic | 4 doors + roof | 60,000 – 95,000 | –3 to –5 dB |
Standard | + 4 wheel arches + trunk | 120,000 – 180,000 | –6 to –8 dB |
Premium | + floor + headliner + firewall | 210,000 – 320,000 | –10 to –13 dB |
Maximum | + pillars + 3rd row + double floor | 360,000 – 480,000 | –14 to –17 dB |
Cost by zone
Zone | Price, ₽ | Time |
|---|---|---|
4 doors (heavy) | 32,000 – 55,000 | 7–10 h |
4 wheel arches (large) | 40,000 – 65,000 | 6–9 h |
Roof | 32,000 – 52,000 | 4–6 h |
Floor + tunnel (large area) | 55,000 – 95,000 | 10–16 h |
Trunk + spare well | 28,000 – 45,000 | 5–7 h |
Firewall | 28,000 – 45,000 | 5–7 h |
Headliner (with disassembly) | 32,000 – 50,000 | 6–8 h |
LC 300 specifics
Body-on-frame. Body-on-frame transmits vibration differently than monocoque. Wheel arch and floor soundproofing matter more than doors here.
Third row. 7-seater config adds work: each seat removed, floor underneath treated. +20,000–30,000 ₽.
Diesel 3.3 V6. Diesel is louder than V6 gas 3.5. Firewall gets one extra layer — +5,000–10,000 ₽.
Off-road tires. All-Terrain or MT — significant noise comes from tires. Wheel arch soundproofing gives max effect here (–4 to –6 dB from arches alone).
Timing
Premium on LC 300 — 5–7 working days. Maximum — 7–10 days. Body volume is larger than a sedan, so each zone takes longer.
FAQ
Should I do soundproofing before switching to M+S tires?
If you'll switch to less aggressive tires in winter — wheel arch soundproofing gives even more pronounced effect then. With winter tires the dB difference is smaller, but baseline improvement stays.
How much weight added?
Premium — +35–55 kg, Maximum — +60–80 kg. On LC 300 less noticeable than on a sedan: it already weighs 2.5+ tons. Almost no fuel impact.
What about air suspension on ZX?
Soundproofing doesn't touch it. We work above frame level — air suspension and its sensors stay untouched.
Can I do it in stages?
Yes. Most common path — arches + doors first (Standard), then floor and headliner 6–12 months later. 10–15% pricier total due to repeated teardowns.
