Trojan Trailer Parts Best Sellers: The Wheels, Locks, Lights and Spring Kits Kiwis Are Buying Now

Labour Day has been and gone, the evenings are getting longer, and trailers all over the country are coming out from behind the shed. Before you hitch up for the first boat launch or bach run of the summer, it's worth a quick walk around the trailer: tyres, lights, springs, coupling, and how you lock it up when it's parked. We went through our actual sales from the last 90 days to see which Trojan Trailer Parts Kiwis are buying right now, and this round reads a lot like that checklist.

1. Trojan 14" Trailer Wheel and Tyre – 850kg, Galvanised Rim

This is a complete, ready-to-bolt-on wheel: a galvanised steel rim with a 185/14" 8-ply light-truck tyre, on the Ford 5 x 4.5" stud pattern. Overall diameter is 645mm, and it's rated to 850kg as a single wheel (800kg per wheel in dual set-ups). The galvanised rim is the big drawcard for boat trailers that get dunked in salt water every weekend.

People buy these to replace a tired, cracked tyre on a rusty rim in one go, or to finally carry a proper spare. Check your stud pattern before ordering.

2. Trojan Heavy Duty Protector Coupling Lock

A parked trailer is an easy target. Trojan's Protector lock fits 50mm and 1 7/8" ball couplings, works on plunger or lever couplings, and uses a solid 15mm hexagonal steel lock bar. It's bright red on purpose, so anyone eyeing up your boat or caravan can see straight away that it's locked.

It's a regular buy for anyone who leaves a boat trailer, caravan or tradie trailer on the street or at a storage yard.

3. LED Tail Light Set – 100 x 100mm, 10–30V

Lights are often the first thing to give up on a trailer, especially one that gets backed into the sea. This set comes as a left and right pair, with stop, tail, indicator, licence plate and reflector functions all built into each low-profile 100 x 100mm lamp. It runs on 10–30 volts with 400mm cable leads, and it's ADR compliant.

It's an easy upgrade from old globe lights for anyone tidying up a trailer before summer.

4. Trojan 1000kg TaperLeaf GV Spring Kit – Single Axle

If the springs are sagging or rusted through, this kit has everything in one box. You get a pair of 45mm taper leaf springs plus hangers, slippers, U-bolts, plates and bolts. It's rated at 1000kg per pair and Dacromet coated to resist corrosion. Eye to centre bolt is 765–350mm, so measure your old springs first.

Buyers are mostly DIY trailer owners who'd rather replace the whole suspension set-up at once than chase individual parts.

5. Trojan Zinc Coupling – 2000kg, 50mm, 2-Hole

A sloppy or seized coupling is no fun at the ramp. This one is steel with a zinc-plated finish, suits a standard 50mm tow ball, and is rated to 2000kg with a simple two-hole mounting. It's a straightforward swap on boat, utility and light commercial trailers.
