EFS Heavy Duty Torsion Bar Set, 2 Inch - Daihatsu Rocky and Feroza 1988-1998

The Rocky and Feroza are light vehicles, so every kilo added to the nose shows immediately in ride height. A bar, a winch, an extra skid plate - and the factory torsion bars have to be wound up further and further until the adjustment runs out and the front end turns harsh.

This set of two EFS heavy duty torsion bars measures 26 mm in diameter and 1093 mm in length, and is 25-30% stronger than the original bars. The material is XK-5160 high carbon steel and the spline has 37 teeth.

Key benefits

• 25-30% more strength than the factory bars is welcome on a vehicle whose front end now carries more than its designers planned for thirty years ago.
• A thicker bar twists less under the same load, so the suspension controls body movement instead of bottoming out.
• XK-5160 steel is specified for torsional fatigue - exactly the load a torsion bar carries over every bump.
• Colour coded ends (green front, blue left, red right) keep the fitting straightforward and remove the most common mistake.
• On a vehicle of this age, new bars are often the only way to get correct front ride height back - originals can be fatigued after decades of work.

What is supplied

A set of two torsion bars - left and right, covering the whole front axle.

Who it is for

For Rocky and Feroza owners who use the vehicle off road and have added anything heavier than the factory equipment up front. Equally for anyone whose front end has simply settled over the years beyond what adjustment can fix.

Check your body version: the F300 covers 1988-1992 and the F310 Wide Track covers 1992-1998. The same part number serves both.

Fitting notes

• The bars are fitted as a pair, following the colour coded ends.
• Once fitted and the front height is set, the front axle needs aligning.
• On vehicles of this age it is worth checking control arm bushes and bar mounts while everything is apart - they are often more tired than the bar itself.

Why it is worth it

• A new part for a vehicle where good suspension components are getting hard to find.
• 25-30% more strength than the original and a named material instead of an anonymous replacement.
• A complete axle set with fitting marks.

If you are bringing a Rocky or Feroza back to off-road form, the torsion bars are where correct front ride height starts.
