Hey everyone,
I thought it would be a good idea to have all the OEM measurements on 120, Hilux, 150 and FJ front struts to show the geometrical differences and how the strut and bush dimensions have evolved. All measurements are below;
Prado 120 OEM Tokico 48510-60340 (2003-09)
Outer ring eye diameter = 48.45mm
Ring eye wall thickness = 4.22mm
Crush tube ID = 14.25mm
Crush tube OD = 20.55mm
Crush tube length = 39.35mm
Coil seat height = 210.78mm (from ring eye centre)
Strut diameter = 48.95mm/44.85mm
Strut body length = 310mm
Strut post length = 71.85mm
Shroud length = 169mm
Shaft diameter = 12.10mm
Strut body top to ring eye bottom = 430.30mm
Closed-Open lengths = 420-540mm
Strut weight = 2.43kg
Hilux OEM Tokico 48510-0K410 (2005-15)
Outer ring eye diameter = 50.25mm
Ring eye wall thickness = 5.05mm
Crush tube ID = 14.25mm
Crush tube OD = 20.50mm
Crush tube length = 39.35mm
Coil seat height = 228.88mm (from ring eye centre)
Strut diameter = 45.55mm
Strut body length = 314mm
Strut post length = 71.45mm
Shroud length = 164mm
Shaft diameter = 12.05mm
Strut body top to ring eye bottom = 435.70mm
Closed-Open lengths = 430-555mm
Strut weight = 2.28kg
Prado 150 OEM Tokico 48510-60221 (2009-15)
Outer ring eye diameter = 52.10mm
Ring eye wall thickness = 5.09mm
Crush tube ID = 14.25mm
Crush tube OD = 25.25mm
Crush tube length = 41.40mm
Coil seat height = 211.95mm (from ring eye centre)
Strut diameter = 48.70mm
Strut body length = 310mm
Strut post length = 70.80mm
Shroud length = 169mm
Shaft diameter = 12.10mm
Strut body top to ring eye bottom = 432.90mm
Closed-Open lengths = 432-555mm
Strut weight = 2.53kg
FJ Cruiser OEM Tokico 48510-35511 (2011-15)
Outer ring eye diameter = 52.22mm
Ring eye wall thickness = 5.06mm
Crush tube ID = 14.26mm
Crush tube OD = 25.23mm
Crush tube length = 41.57mm
Coil seat height = 213.89mm (from ring eye centre)
Strut diameter = 48.70mm
Strut body length = 310mm
Strut post length = 71.56mm
Shroud length = 160mm
Shaft diameter = 12.01mm
Strut body top to ring eye bottom = 433.78mm
Closed-Open lengths = 435-540mm
Strut weight = 2.61kg
There are several interesting points to note;
1. The first generation 120 strut started out with a reduced (48.95mm/44.85mm) section in the body, neither the Hilux, 150 or FJ uses a reduced section.
2. By the time the second generation Hilux strut was released, the ring eye wall thickness had increased from 4.22mm to 5.05mm, but the Hilux retained the same crush tube as the 120. However the outer ring eye diameter had increased by 1.80mm which gives 39.65mm for rubber bush OD in Hilux, 40.25mm OD for 120. Within error this is the same bush. It's quite difficult to measure the ring eye wall thickness accurately with the bush still in there.
3. Coil seat height on the Hilux strut is longer by 18.10mm compared to the 120 strut.
4. The third generation 150 strut has a thicker and longer crush tube and 41.50mm OD for the bush, so it's a totally new bush design.
5. The fourth generation FJ strut appears identical to the 150 strut, and just uses a shorter shaft.
6. The shaft diameter of around 12mm is the same for all generations.
7. The strut bush cradle arms in the lower control arm are separated by 40.41mm in the 120/Hilux giving around 1mm of wiggle room to fit the 120/Hilux crush tube. This demonstrates you’ll need to shave down a 150 or FJ strut (including after market ones) to get them to fit the 120/Hilux bush cradle. It should also be noted that the 150/FJ struts are higher rebound struts matched to significantly higher rate coils compared to the 120/Hilux.
Big thanks to John at Zordos Suspension who provided all the OEM struts for me to measure.
