Description:
Toyota 4Runner/Surf
1989 On (Coil Rear)
Sold under both the 4Runner and Hilux Surf badges (depending on trim) this mid sized SUV has become popular with tourers what are not looking for a full sized wagon like the LandCruiser or Patrol. The Australian release came originally with a leaf sprung rear end, which was replaced with a coil sprung version in later models. Overseas, the Surf was also released with a strut front end, similar to the LandCruiser Prado. This strut equipped surf is not compatible with Tough Dog suspension.

41mm Foam Cell Struts : 41mm Bore Foam Cell Shock Absorbers
Tough Dog’s award winning Foam Cell shock is our best selling shock for all round performance. Whether you head bush on the occasional weekend or for the majority of the year, Foam Cell shocks will handle your application.
The ‘Foam Cell’ that makes all the difference is a micro-cellular foam insert that helps to drastically reduce the effects of shock fade, allowing your shocks to perform better for longer, even on the harshest of corrugations. Cavitation and Aeration are the undoing of any shock absorber. As the shock is worked harder, the oil and gas in the outer chamber begins to mix and form bubbles, lowering the viscosity of the oil. When this aerated oil passes through the valve, there is reduced resistance, stopping the shock form performing correctly. The Foam Cell insert, with its trapped gas micro cells takes up the empty space in the shock normally taken up by air or nitrogen gas. This eliminates the possibility of bubbles forming, allowing the shock to get on with the job with an unparalleled resistance to shock fade.

Torsion Bars:
Tough Dog Performance 4WD Torsion Bars offer a spring rate that is approximately 30% higher than OEM bars.
This dynamic increase in spring rate eliminates hard bottoming out when travelling off road and gives better handling in street applications. They can be installed with a moderate pre-load to raise the vehicle for better clearance off road, or to revitalise the handling characteristics at the standard height. These performance-proven, easy-to-install bars are especially beneficial when oversize tyres or frontal accessories are installed. Regardless of the torsion bar used, or the accessories fitted, a minimum 60mm of suspension droop (down travel) must be maintained.
Optimise your 4WD’s ride & handling characteristics with quality torsion bars from ToughDog!
Leaf Springs:
Designed in Australia, Tough Dog leaf springs offer a spring pack for just about any application you might require. Our springs are a proven performer in any situation.
Tough Dog leaf springs are a truly progressive rate leaf spring. Each leaf is set slightly higher than the leaf above so there is contact along the whole length of each leaf. There are single stage and two stage springs available for different applications. Primary and secondary stage leaves ensure that the vehicle’s ride remains uncompromised. As the spring is compressed under load, the heavier second stage leaves come into play to prevent excessive sag & remove high stresses from the primary stage.
