Trojan Trailer Parts Best Sellers: The Electric Winches, Couplings, Coupling Locks and Spring Kits Kiwis Are Buying Now

Summer towing season is nearly here. Boats are coming out of the shed, caravans are getting packed for the Christmas break, and plenty of trailers will spend time parked at boat ramps, campgrounds and driveways over the holidays. We went through our real sales from the last 90 days to see which Trojan Trailer Parts Kiwis have been buying. This round is about getting the boat on the trailer easily, hitching up properly, and making sure nobody else can hitch up to your trailer while you're away.

1. Fulton XLT 10K Electric Winch

If winding the boat up the trailer by hand at the end of a long day sounds familiar, this is the upgrade. The Fulton XLT 10K is a fully DC-powered winch for boats up to 26ft, with power in, power out and free spool. A wireless remote lets you run it from the trailer or the dock, and the strap has a swivelling hook and a 3-position guide so it feeds out straight. If the power goes, there's a manual override that works with standard tools.

It's bought by boaties with bigger trailer boats, and by anyone who launches on their own and wants an easier retrieve.

2. Trojan Plunger Coupling – 3500kg

This was one of the busiest couplings of the last three months. It's rated to 3500kg and fits both 50mm and 1 7/8" tow balls, so you don't need different hardware for different vehicles. An anti-rattle screw cuts down movement and noise on the road, and there's provision for a security padlock. In 50mm mode it complies with NZS 5232-1993. It bolts on with four 12mm high-tensile bolts, uses the same mounting footprint as Trojan override couplings, and works with electric or driver-operated brakes.

Buyers are mainly people with farm trailers, work trailers and heavier caravans.

3. Security Lock for Cruisemaster DO35 and DO45 V1 Couplings

Off-road caravans and camper trailers often run a Cruisemaster DO35, and this lock is made for it. The kit comes with a dummy pin, two keys and a lock chamber with a dust cover. The pin goes into the DO35 universal joint, the lock goes on the end, and the coupling can't be used. Nobody else can hitch up to your van while you're out for the day. One thing to check first: it suits all versions of the DO35 and the DO45 V1 only. It does not fit the DO45Plus.

4. Trojan Trailer Coupling Lock – Suits TC2500

Here's the budget-friendly way to secure an everyday trailer. It has a hardened steel lock and pin, comes with keys, and locks the coupling whether the trailer is hitched up or not. On Trojan TC30 couplings it replaces the standard lock pin. On Duofit couplings it fits into the coupling head and stops the handle from being lifted.

It's a common add-on for boat and box trailers that get left at the ramp or on the street.

5. Trojan 1500kg Multi-Leaf Spring Kit – Pair, Single Axle

Sagging springs are a classic pre-summer job. This short series kit is rated to 1500kg per pair, with a 4-leaf pack (45 x 6mm), 16mm eyes and a Dacromet coating for corrosion resistance. It comes with everything for a single-axle install: a pair of springs, hangers, bolts, slippers, U-bolts and plates. There's no hunting around for extra hardware.

It's bought by people restoring an older trailer or getting a utility or boat trailer back to riding level.

Small parts sold steadily too. The 1 7/8" zinc towball rated to 3500kg ($19.99) and the trailer safety chain kit for up to 2000kg ($29.99) are easy wins if yours are looking tired. Boat trailers with MK3-MK7 hydraulic calipers have been getting the stainless steel brake pad set ($137.00). There's more in towing and brake components.
