Lewmar genoa car and traveler parts are sold by size (0 through 3) and part type, not as one universal kit — and MAURIPRO stocks the genuine cars, complete track kits, becket assemblies, cam plates, ball-bearing refills, and hardware spares across the whole range. Match your car's size code and line (T-Track, NTR, or the discontinued Ocean series) before you order, and the part fits without a return.
This is written for the cruiser (~30-45 ft) whose genoa car sticks, rattles, or has a worn cleating cam — and who wants to fix the part that actually failed rather than replace the whole traveler system. Lewmar's genoa car and traveler hardware is modular on purpose: the car, the track, the ball bearings, the cam plate, and the end hardware are all sold as separate spares, sized to a specific car generation.
Get the size and line right and the spare bolts straight onto the track you already have. Get it wrong — order Size 2 balls for a Size 1 car, or NTR hardware for an older Ocean-range system — and you'll be re-ordering before the car runs smooth again.

Do I need a single spare part, or a complete genoa car kit?
If the track itself is straight and undamaged and only one component has failed — the ball bearings, the cam plate, a becket, or a stirrup screw — you only need that individual spare. Lewmar sells the wearing parts of a genoa car separately for exactly this reason: a bag of Delrin balls or a cam plate replaces the part that actually failed without disturbing the track, the car body, or the deck-mounted end stops. Reach for a complete kit — like the NTR Line Control Kit or an Ocean-range Kit, which bundle track, cars, and end stops — only when you're upgrading an older or damaged track system, converting to line-controlled cars, or replacing a car whose body itself is cracked rather than just worn.
How do I know which Lewmar genoa car size I have?
Lewmar's genoa car and traveler track comes in a numbered size range — Size 0 through Size 3 — matched to boat length, and the T-Track cars all ride on the same industry-standard 32 mm (1 1/4 in) track profile regardless of size, per Lewmar's own product specifications. As sized in Lewmar's own kit listings: a Size 0 Ocean Kit is built for boats up to 8.5 m (28 ft), a Size 1 NTR kit for boats up to 11 m (36 ft), and a Size 2 NTR kit for boats up to 15 m (49 ft) — with Size 3 hardware serving the largest boats in the range. Confirm your size against the part number stamped on the car body or track end cap before ordering a spare; parts don't cross-fit between sizes even though the overall car shape looks similar.
What parts wear out first on a genoa car or traveler?
The Delrin ball bearings inside the car are almost always the first thing to go — they take direct load every time the car moves under sheet tension, and salt or grit trapped in the track accelerates wear until the car starts to bind or feels gritty instead of sliding smoothly. The cam plate is the second most common failure: repeated cleating and releasing under load wears the cam's grip surface until it slips instead of holding the control line. Becket links, stirrup screws, and slide rods wear more slowly, but they're still sold as standalone spares because a single fatigued link shouldn't force a full car replacement.
Can I replace just the ball bearings, or do I need the whole car?
In most cases you only need the ball refill or ball conversion kit for your car's size — not the whole car. A Delrin ball bag refills the bearings inside an existing car body, and a Replacement Ball Conversion Kit does the same job with additional hardware for cars that need it. Replace the whole car only if the car body itself is cracked, the sheave has failed, or the stirrup/becket mounting points are damaged beyond the individual spare's scope.
Are older Lewmar Ocean-range parts still available?
Some are, but the line itself is discontinued. Lewmar's Ocean car range is now obsolete, and MAURIPRO still carries a limited set of genuine Ocean spares — including slide rods and screws — while supply lasts. If you're running an Ocean-series system and a core component like the car body or track fails outright, plan on a full Ocean Kit replacement or a track conversion rather than waiting on a spare that may not be restocked.
Which should I choose?
Order the individual spare — balls, cam plate, becket, or screw — whenever the track and car body are sound and only one component has failed; it's the faster, cheaper fix and doesn't touch anything you don't have to. Order a complete Genoa Car Kit or NTR Line Control Kit when you're upgrading an older non-line-control system, replacing a damaged car body, or standardizing an Ocean-range boat onto currently supported hardware. Either way, confirm the size code against your existing track before you check out — Lewmar doesn't publish a universal spare that fits every size.
Expert notes
From our rigging bench: the single most common support call we get on genoa cars isn't a broken part — it's a car that's simply packed with dried salt and grit inside the ball track. Before ordering a ball refill, flush the track with fresh water and cycle the car a few times; if it still binds, the balls (or the track surface itself) are genuinely worn and the refill is the right fix.
On boats that add a 2:1 or 3:1 purchase off the traveler car for easier trimming, the becket assembly is the part that takes the extra load — inspect it seasonally on any boat rigged this way, since it sees cycling the base car hardware never was designed around.
Common mistakes
- Ordering by "size" alone without confirming the line. T-Track, NTR, and the discontinued Ocean series all use different hardware even at the same nominal size — match the line, not just the number.
- Assuming Size 2 and Size 3 parts are interchangeable. They aren't; the car body, track width, and ball diameter all change between sizes.
- Replacing only the balls when the cam plate is also worn. A car that still slips or won't hold tension after a ball refill almost always needs the cam plate too — inspect both before you order.
- Waiting until an Ocean-range part fails completely. Spares for the discontinued line are limited — order proactively if you're still running that system.
Frequently asked questions
Where can I buy genuine Lewmar genoa car and traveler replacement parts?
MAURIPRO stocks genuine Lewmar genoa car and traveler spares — Delrin ball refills, cam plates, becket assemblies, cleat plates, and complete kits — sized to Size 0 through Size 3 hardware.
How do I know what size Lewmar genoa car system I have?
Check the part number stamped on the car body or track end cap against Lewmar's size range: Size 0 fits boats to 8.5 m (28 ft), Size 1 to 11 m (36 ft), and Size 2 to 15 m (49 ft), with Size 3 serving the largest boats in the lineup.
Can I replace just the ball bearings in my genoa car?
Yes. A Delrin ball refill or ball conversion kit replaces only the bearings inside an existing car body and is the correct fix for a car that binds or feels gritty but is otherwise structurally sound.
What's the difference between a Genoa Car Kit and an NTR Line Control Kit?
Both bundle track, cars, and end stops for a complete replacement. The NTR Line Control Kit adds line-control hardware so the car can be adjusted under load from the cockpit, while the standard Genoa Car Kit is a like-for-like track and car replacement without that feature.
Are Lewmar Ocean-range parts still available?
Some are — MAURIPRO carries a limited set of genuine Ocean spares — but the line itself is discontinued, so plan on a full kit replacement if a core component fails outright.
Do Lewmar traveler parts fit tracks from other manufacturers?
No. Lewmar's car, ball, and cam hardware are sized and profiled specifically to Lewmar's own track sections and aren't cross-compatible with other manufacturers' traveler systems.
