Direct-fit aftermarket replacement, machined from 4140 PG Bar at the Enex workshop in Malaga, Perth WA. Made to original equipment spec — no rework, no spacer kits.
A 90mm pin is a load-bearing pivot point on a heavy-haulage trailer — it carries shear load while components articulate around it. Under constant working load and grit ingress, pins wear oval, score and develop play. EE013 replaces a worn pin to original diameter and finish. Confirm fit by sending your worn part, photo or dimensions.

Worn trailer pins announce themselves before they fail. Watch for knocking or clunking over bumps and through turns, visible play when you lever the joint, a pin that has gone oval, scored or stepped, or stiff, notchy articulation where it should swing freely. Left too long, a worn pin chews out the mating bush or housing and turns a cheap pin job into a bigger repair.
EE013 is machined from 4140 chrome-moly bar — a high-tensile, fatigue-resistant grade used for shafts and pins because it holds its diameter under heavy shear load. Cut to your original diameter and finish, it drops straight in: no rework, no spacer kits, no surprises on the bench.
If you're unsure EE013 matches your worn part, photograph it with a tape measure across the critical dimensions and email contact@enexengineering.com.au. We'll confirm fit before you commit.

4140 chrome-moly bar. It's a high-tensile, fatigue-resistant grade used for shafts and pins because it resists bending and holds its diameter under repeated heavy shear load — the right material for a pivot pin that works every load cycle.
Yes. If the bore or bush has worn, we can machine an oversized pin (or supply a matching bush) to take up the slack rather than just replacing like-for-like. Send the worn parts and we'll advise the best fix.
