Description
Toyota Hilux Ring and Pinion 3.72 Ratio Terrain Tamer
A Terrain Tamer Hilux ring and pinion set in 3.72 ratio, built for the Toyota Hilux 8″ differential. Terrain Tamer manufactures it to Toyota’s original specification, so it handles tough off-road terrain, heavy towing and everyday driving without compromise.
Specifications
- Ratio: 3.72
- Differential: Toyota Hilux 8 inch
- Heat treated for strength and wear resistance
- Precision cut teeth for smooth, quiet running
- Manufactured to OEM specifications
- Supplied as a complete crownwheel and pinion set
Every set is heat treated for strength and wear resistance, with precision cut teeth for quiet running. Built to OEM standards, it fits and drives like the factory gear set it replaces, at well under genuine Toyota pricing.
Choosing the right Hilux ring and pinion ratio
Fitting larger tyres raises your effective gearing, which makes the truck feel sluggish off the mark and puts the auto hunting between gears. Dropping to a numerically higher ratio brings it back. As a rough guide, going from standard tyres up to 33s usually calls for one step, and 35s two. If you run front and rear diffs on a four-wheel drive, both must be the same ratio.
Not sure what you have now? Check the tag on your diff housing or give us a call, and we will confirm it before you order.
What else you need
A ratio change means the diff has to be stripped and set up again, so it is worth doing the wear items at the same time. You will need a bearing kit, and we recommend a solid pinion spacer in place of the collapsible crush sleeve on any diff that works hard. Fresh gear oil goes in on assembly.
If you are upgrading the centre while it is apart, we also stock the Hilux 8″ Disctrac LSD, the Kaaz Super Q 1.5 way LSD, and a 30 spline full spool.
Prefer it done for you?
We build and set up Hilux diffs in our Christchurch workshop every week. If you would rather not tackle the setup yourself, look at our Toyota 8″ Hilux and Hiace rebuilt exchange diff, built to your ratio, ready to bolt in, with your old unit going back as the exchange.

★★★★★ Sorted the clunk
Dave P · Nelson · Example review Rang the team first to check it was the right one for my rego. It was. Fitted by my local mechanic, no more clunk on take off.
★★★★★ Quiet as new, swapped it over in an afternoon
Mark T · Timaru · Example review Had the classic whine at 80. Diff turned up next morning, swapped it over myself with the fitting guide, return label was in the box. Three weeks on and dead quiet. Core charge came back inside a week.
Reply from the Gearhead Diffs teamCheers Mark, glad the guide did the job. Thanks for getting the core back quick.
