I recently fitted a Wavetrac http://www.wavetrac.net/index.htm diff centre and I’m rapped with my choice.
Was originally going to fit a Harrop true trac but decided on the wavetrac after reading many forum reviews especially overseas.
I found a wet road yesterday and it just sat on the rear and jumped off the line.
Had a bit of a read and it sounds like a really good diff, looks like it comes with a solid warranty aswell
What’s the difference.
Difference between true trac and wavetrac or warranty.
Firstly Wavetrac warranty is lifetime even if street legal racing, drag or circuit, providing right oil is in diff.
As for the difference better off reading this:
What did it cost you roughly? Did you change gear ratios as well?
Drive in drive out, Wavetrac supplied and fitted with a complete overhaul new bearings etc and lapping of original 3.46 gears was $2900.
I’ve already tried 3.73 gears previously for about a year but as my cam/head combo is more about low to mid power I found the 3.73 too short for every day driving plus highway use.
Damn not cheap. What’s the center worth? Keen to see if they uphold a warrenty not many people do. ESP with racing etc.
The wavetrac is about $400 dearer than the similar cased Harrop true trac so a lot dearer than the cast Eaton version.
But it was how it puts its ower down is what I wanted most.
Yes at the drags in the dry there would probably be no difference in how the wavtrac and truetracs power down.
The main difference is in slippery situautions like mud or wet grass where the wavetrac maintains drive to both wheels at all times and these are situations that I find my self a few times a year.
I’m not saying they are for everyone but it is what I want out of my car that matters to me so I’m more than happy with the outcome.
Main place the WaveTrac will win hands down is if you lift a wheel while cornering ie circuit racing or spirited twisties, the TrueTrac will have 0 drive in these conditions…
I used an off road 9″ True Trac in my Old Supra, they have a small preload clutch pack to prevent the 0 drive condition but had to be retuned for the smaller diameter street tyres as they’re set up for 33″ tall Mud tyres.
Had the Harrop TrueTrac in the Tonner and it behaved itself even in wet slippery conditions on grass/mud but that may have been CrossTrac helping out.
Wow. I didn’t even know these existed??
Very interesting to read though, their warranty claims are quite impressive (though I’d love to hear a few claim examples). But on the whole, the design is very clever. I was under the impression that a TruTrac would still power both wheels even when one had zero load???
Something else I found interesting:
“use the gear oil spec that your car manufacturer recommends for your car. The Wavetrac® is compatible with virtually all factory-installed gear oils used today”
“There is no additional maintenance required when using the WAVETRAC differential. You can simply install it and “forget” it!”
So you can use just about any oil in the diff (minus some exceptions on their website), and you’ll never have to do any maintenance on the wavetrac??? That’s a big bonus there

If you can get a little bit of load onto the 0 load axle (tap the brakes or pull the handbrake) they will load up enough to lock up and drive both axles..
If you can get a little bit of load onto the 0 load axle (tap the brakes or pull the handbrake) they will load up enough to lock up and drive both axles..I agree but I’ve been stuck on wet frosty grass and could not get any where (old holden LSD) and so was my smart alec mate in his old VZ ute with true trac who was laughing at me going nowhere before he tried.We both had to get pulled across the grass by the land owners tractor.My mate now has a new VF Clubby W507 and is seriously considering the wavetrac if its the same as the VE one.As I said its not for every one I just decided thats the way I wanted to go and the few of us on these forums that have them love them.But the majority on here would get all they need from the cheapest Eaton true trac, Cheaper than replacing the original LSD centre. -
