Superior Rock Rod 4140 Comp Spec

Why Choose Superior Engineering Rock Rods?

Stronger by Design

• Manufactured from 4140 solid high tensile steel, not weaker mild steel.
• No machined flat sections for adjustment, which reduces material thickness and weakens the rod. Instead, Rock Rods are designed for simple installation using vise grips or stilsons.
• CNC machined threads ensure precise fitment and compliance with steering tolerances.

Premium Hardware

• Supplied with quality tie rod ends, greasable style where available, or pre-greased units depending on supply.
• Toyota applications use male tie rod ends, while Nissan applications generally use female ends.
• Replacement boots and spare parts are available for long-term serviceability.

Corrosion Protection

• Every rod is coated in SA5 zinc, a finish that outperforms paint and powder-coat in resisting rust, water and dirt.
• Matching SA5-coated damper brackets supplied at no additional cost, something many competitors charge extra for.

Proven Material Choice
The same 4140 high tensile steel used in Superior Engineering Rock Rods is also trusted in critical industries for:

• Gear and engine construction
• Crankshafts, pulley shafts and connecting rods
• Spindles and motor axle shafts
• High tensile bolts
• Mining, agriculture, transport and earthmoving components

Rock Rod FAQ's

Q1: Are these the strongest steering rods on the market?
A: We believe so. They’re engineered to handle extreme loads while still allowing controlled deflection to protect associated steering parts.

Q2: Can they bend?
A: Any steering rod can bend under enough force, but these are extremely resistant. If made any stronger, they could risk damaging knuckles or other steering components instead.

Q3: Do they come complete with tie rod ends?
A: Yes, all Rock Rod assemblies are supplied with tie rod ends ready to install.

Q4: Do I need to buy a damper bracket?
A: No—unlike other brands, a SA5-coated damper bracket is included where required.

Q5: Are replacement parts available?
A: Yes. Superior Engineering stocks spare tie rod ends, damper brackets and rubber boots.

Q6: Will they rust?
A: All steels can rust, but SA5 zinc coating provides one of the highest levels of corrosion resistance available. Regular maintenance will maximise longevity.

Q7: Do I need different rods for different lift heights?
A: Generally, no. Most Toyota and Nissan applications are a one-size-fits-all solution.

Q8: How quickly can I get one?
A: Orders typically leave our Brisbane warehouse within one business day, with delivery time depending on your courier.

Q9: Do they use left- and right-hand threads?
A: Yes, allowing easy on-vehicle adjustment.

Q10: Will they fix steering problems?
A: If your steering rod is worn or bent, replacing it with a Rock Rod will solve that issue. However, other worn components may also need replacement for safe steering.

Q11: Are they too heavy?
A: The largest, the GU Patrol tie rod, weighs approximately 11kg. This added weight has no negative effect on steering or suspension performance.

Q12: What warranty do they carry?
A: All Comp Spec 4140 Rock Rods come with a 12-month manufacturing defect warranty, plus a Limited Lifetime Warranty against bending. If you manage to bend a Rock Rod, Superior Engineering will repair or replace it at our discretion (freight and fitting costs excluded).
