speedo correction

No eBay APP ID and/or Cert ID defined in Kunena configurationanyone know if this would work on my jimny to correct the speedo after fitting 30" tyres?




i know a few of you guys have used the Jaycar one but they seem to have taken it off there UK website..

Thanks
Tom

Have a look at www.4x4tyres.co.uk top right corner of the home page is the tyre size calculator which show size you have & size you want next to it with all diameters, wall sizes etc. and at the bottom shows how much your speedo will be out by at any given speed.

I prefer to change the number of teeth on the speedo gear (inside the t-case)

With tyres of that size I assume you have gone down the Rock Lobster route, Then you can contact a nice guy called Rockwatt on this forum and he can supply a 27 tooth speedo ring that will go on the rear output flange on the SJ box. The jimny transfer case has a 25 tooth speedo ring.

cheers for the coments guys.


i think it still has standard t box, when i bought it it has 31"s on it with 3" lift and 2" body lift... the 31's where massive so i have downsized to 30s.. only doing a bit of green laning really, if it breaks then may build up a rocklobster for it, will see how it goes..

i was just wanting to sort the speedo out for road use.. could put stickers on the dash but id rather do it properly!
thats why i wanted to know if the adaptor on ebay would work the same as the jaycar one and i can just wire it inline to speedo and adjust!

cheers

I'm running 30's and 31" on mine and I use a speedohealer.

Fantastic bit of kit. Easy to install and does what it's supposed to do.
They even have a android app for your smartphone that guides you through the setup process, although it isn't overly complicated and can be easily done without it.
