obp Motorsport Imperial Male Left Hand Rod End

Engineered by obp Motorsport in the UK, these high-tensile imperial male left-hand spherical rod ends are purpose-built to deliver smooth, slop-free linkage articulation under rigorous motorsport conditions. Fabricated from premium 230M07Pb carbon steel, the housing provides exceptional structural strength for high-load suspension, steering, and throttle linkage configurations on the track.

The spherical bearing relies on a hardened 100Cr6 bearing steel ball captured within an advanced GR-Nylon PTFE injected liner. This self-lubricating lining eliminates metal-on-metal friction, isolates fine grit, and ensures a long-lasting, fluid operating feel that handles heavy axial and radial vibration without binding.

Key Technical Features:

• Carbon Steel Housing: Extruded and machined from robust 230M07Pb steel for maximum tensile strength and resistance to structural distortion.
• PTFE Injected Liner: Advanced GR-Nylon PTFE injection-moulded race continuously self-lubricates the bearing interface while sealing out dirt and fine paddock debris.
• Hardened Steel Ball: Inner core is machined from premium 100Cr6 bearing steel and heat-hardened for maximum wear resistance.
• 2-Year Warranty: Backed by obp Motorsport’s comprehensive structural warranty, certifying professional-tier British manufacturing.

Frequently Asked Questions (FAQs)

Q: Why do I need a left-hand thread rod end?

A: Left-hand thread rod ends are used on one end of a linkage arm paired with a right-hand thread on the opposite end. This layout allows you to adjust the total length of the linkage rod simply by spinning the centre bar, without having to disconnect either end.

Q: Does this rod end require regular manual lubrication or greasing?

A: No. This joint features an injection-moulded GR-Nylon PTFE liner that self-lubricates during operation. Adding external grease or spray lubes is not required and can actually attract dirt or paddock grit, shortening the service life of the internal race.

Q: Is this rod end safe to use for structural Autograss suspension setups?

A: This specific carbon steel unit is perfect for linkage rods, throttle controls, anti-roll bars, and pedal hydraulic interfaces. For high-impact main suspension control arms or heavy-duty steering tracks, we recommend stepping up to a high-strength Chrome Moly (Chromoly) steel joint variant.
