This so good thanks mate. But would have been good to see the transfer case and auto gearbox breathers extended to.

[@2ndGearLow]

Thanks for the feedback and suggestion!

The breathers in the Mount rattle

[@2ndGearLow]

Hi Jack, we've noticed the same thing. The best way to minimise the rattle is to push the hose on the breather end as far on to the barb as possible. Hope this helps!

[@dfnkhff4jbg7]

@@2ndGearLow I'm a auto engineer I made a new mount and put the crap assembly it came with on the bin . Better to just make your own kit at 45% of the rrp

[@Nickysticksofficial]

Thank you!! This is great!

[@Nickysticksofficial]

Got a 98 Lc from Japan and I’ve been going through big puddles recently. So this is very good to note before I go to some mud flats😂😅

[@2ndGearLow]

Thanks for watching Nicky, and we appreciate your comment. All the best for the Japanese LC, sounds like a great Cruiser!

[@nwilson228]

Great Video! Do you play to extend the transfer case, transmission?

[@2ndGearLow]

Thanks for watching! Yes, I think we will look at another video in future for extending the transfer case and transmission breathers, but we haven't planned one just yet

[@v8s01]

Hey mate how is the fuel consumption in real life? I’m thinking of buying one just want to talk to people who actually own one. Are they actually as bad as people say?

[@2ndGearLow]

I average about 16L/100kms at the moment which is pretty decent considering the weight I've added.

[@Jmjm1969]

Wow 16L. Thats amazing. Mine not less than 19L/100kms. Any advise?

[@MizzFunny]

Well well well. Three holes in the ground.
