Tough Dog heavy duty 32mm torsion bars for the Toyota LandCruiser 100 Series (1998-2007), sold per pair. Pick the length for your engine - 1160mm for petrol models, 1210mm for diesel models. The Tough Dog strengthening bracket kit (4WTB-1610/BKT) must be fitted when installing new torsion bars - add it below.
Tough Dog performance torsion bars run a spring rate roughly 30% higher than the factory bars – the fix for a torsion-bar front end that's sagged under a bull bar and winch, or that runs out of adjustment when you try to wind a bit of height back in.
Cranking worn factory bars just moves them further along an already-tired spring; new, stiffer bars restore proper ride height with adjustment to spare and sharpen up the front end's control. Fit as a pair, set the height evenly side-to-side, and finish with a wheel alignment.
Doing the whole vehicle at once? We also stock the matching rear Coil Springs and rear Shock Absorbers for the Toyota LandCruiser 100 Series.
Match them with Tough Dog front shocks.

Last updated: 27 August 2026
Genuine Tough Dog suspension from an authorised Australian dealer.
These suit the following applications: Toyota LandCruiser 100 Series (IFS Front) 1998 - 2007. Check your build date and variant against the fitment table on this page – if you're not certain, contact us with your rego or VIN details and we'll confirm fitment before you order.
The listed price covers both sides – always replace left and right together so the axle is evenly damped and sprung. Book a wheel alignment straight after fitting: any change to the front end moves camber and castor enough to affect steering and tyre wear.
Tough Dog limits front lift so that rim-to-guard measures no more than 740mm on 16 inch rims or 753mm on 17 inch rims. Winding higher will overload and fail front end components, including the shocks.
Yes - Tough Dog urethane trailing arm bush kits (TDUK-025 upper, TDUK-026 lower) and rear urethane spring spacers (TDUK-1724/15 15mm, TDUK-1724/30 30mm) are available for the 100 Series. Contact us to add them to your order.
Stronger and more stable
The front end feels firmer and handles the extra bull bar weight much better. A worthwhile upgrade for the 100 Series.(5)
