does anybody have any feedback on the Flying Spanners high speed gears ? They've been offering the 5.99's for awhile, but have come out with a 5.1. Right now I have a completely stock C303.

I have a brand new set of their gears sitting in my office waiting for me to have a moment to install them. Service from them was great and the gears look to be decent enough quality. I can't tell the origin of manufacture from the machine markings. I will let you know once I can spare a moment to install them.

Is there any way to get a set of these for a 6x6 application? Or does anyone have a CAD of these or can get that info since flying spanners seems to have gone MIA

I run them in a Jeep with Volvo axles, they are great for highway cruising, Kamo Oko Vidi are now making gear sets very similar. It might pay to visit their website.

KAMO OKO VIDI have both 5.11:1 and 5.99:1 and they have them with the extra "drive" on the pinion for the centre axle on 6x6

So...I can’t give a totally fair review since I also changed engines. But I can say the gears from flying spanners are great. Too bad they appear to have closed their doors. But I think the Croatian companies are made at the same shop. The gears are quiet and build into the diff nicely. The increase in speed or decrease in rpms is very noticeable. But your B30 better be in good condition to drive the extra gearing.

And would definitely be a problem for those who seem obsessed with running 37"+ tires.

37” tires would achieve the same results without changing gears. But anything over 35” is to big for the C303’s cosmetics in my opinion.

Well yes but it should be pointed out that while on paper it's the same, the torque loss is very noticeable when you start going over 35" which is why I wonder how so many of the Euro/Swedish guys I see with 38" or even 40's even drive at all. Top gear would only be effective downhill! You also lose your crawling ability quite a bit over 35". Putting in more power to help with bigger tires just stresses axles, bearings, gears etc.. People need to learn to live with the 35-36" max or get a Unimog.

Or have both a Volvo and a Unimog. I have three mog’s to keep my Volvo company and to keep me from doing something stupid with the Volvo.
