Gear Sets and Ratios for Supercars and Performance Cars

Gear sets are the internals of the gearbox, the actual gear pairs that set how the car is geared and how it engages each ratio. Changing them is how you tailor a car to a job: closer ratios keep the engine in its strongest range between shifts, a shorter final drive sharpens acceleration at the cost of top speed, and dog engagement replaces synchromesh with a design built for fast, deliberate shifts. Gears are also a wear item on cars used hard, so this section covers both the performance route and straightforward replacement of a damaged or worn gear during a rebuild. We supply gear sets and gearbox internals for supercars and performance cars, and we deliver across Dubai and the UAE, to India, and worldwide.

What This Collection Covers

• Close ratio gear sets: full sets that tighten the steps between gears so the engine stays in its useful range through a shift.
• Individual replacement gears: single gear pairs and hubs for rebuilding a box after damage, without replacing the whole set.
• Dog engagement kits: dog rings and modified gears that replace synchromesh for fast flat shifts on competition cars.
• Synchro sets and hubs: synchro rings, sleeves and hub assemblies for restoring clean, quiet shifts on a road gearbox.
• Final drive gearsets: crown wheel and pinion sets in alternative ratios to change overall gearing for a circuit or for road use.
• Shafts, bearings and shims: the input, lay and output shafts, bearings, thrust washers and shims that go in with a gear set.
• Reverse and idler gears: reverse gears, idlers and their bushes, commonly damaged by a hurried shift.

Why It Matters

Gearing decides how a car feels far more than most people expect. A set of ratios that is too widely spaced drops the engine out of its strongest range on every upshift, so the car feels slower than the engine actually is, and this gets worse on a tight circuit. Closing the ratios up keeps it pulling. Changing the final drive shifts the whole spread, which is why a car geared for a long straight is not geared for a technical track. Engagement type matters too. Synchromesh exists to make shifting easy and quiet, and it is the right answer on the road. Dog engagement removes the synchro from the equation so shifts can be made faster and under load, which is a genuine lap time gain, but it is noisier, less forgiving and needs a deliberate hand. If a gearbox is already whining or crunching, replacing the worn gear or synchro is what restores the shift instead of masking it.

How to Choose the Right Gear Set

Start from where the car is used. A road car and a grand tourer are best served by original ratios and fresh synchros, since drivability and refinement are the point. A car doing track days can gain real time from a close ratio set matched to the circuits it runs, keeping synchromesh so it stays usable on the drive home. A dedicated race car is where dog engagement and a circuit specific final drive belong. Whatever the direction, the parts have to suit the exact gearbox, and gear changes are rebuild work, so the shafts, bearings and shimming need to be planned in at the same time. Tell us the car, the year, the exact variant, the gearbox code if you have it, and the tracks or the type of driving you want the gearing to suit. WhatsApp us on +971 50 308 5760 or send us an inquiry and we will work through the ratios with you.

Shipping and Availability

We deliver across Dubai and the UAE, to India, and worldwide. Gear sets are specialist items and most are sourced or manufactured to order rather than held in ready stock. Some service gears and synchro parts are available quickly. We confirm the lead time before payment so a rebuild can be scheduled properly.

Frequently Asked Questions

Which gearboxes do these gear sets suit?
They are specific to a gearbox family. Send us the make, model, year, variant and the gearbox code or a photo of the casing tag and we will confirm what is available.

Do you ship outside the UAE?
Yes. We deliver across Dubai and the UAE, to India, and worldwide, with tracked shipping.

Are gear sets in stock?
Most are sourced or made to order because they are produced in small batches. We confirm the lead time in advance so the workshop time can be booked around it.

Are these genuine parts?
Yes. We supply genuine parts from established manufacturers, including original equipment quality gears and recognised motorsport transmission specialists.

What if the ratio set I want is not listed?
Plenty of options are not shown on the page yet. Send us an inquiry with the car, the gearbox and the ratios you are after and we will source it.

Cannot find the ratios you want above? We can source almost any gear set or gearbox internal for your car. WhatsApp us on +971 50 308 5760 or send us an inquiry with the part and the car it is for, and we will come back with a price and a lead time.
