The GMC CCKW

Right here on this site under Increasing the speed in your CCKW,

it is written:

"D. Finally you can replace all the ring and pinions (banjo axle’d trucks) with lower numerical ratio civilian 1.5 ton truck gears or with the M211 or M135 gears. The M211 and M135 gear ratio is 6.16 to 1 as opposed to the WW2 GM ratio of 6.66 to 1. The difference is only 8% or 48 mph versus 45 mph stock. To me it is not worth all that effort. If you change to the civilian 5.43 to 1 ratio (times 3 differentials), you will get a 25% increase or about 56 mph versus 45 mph stock.

Has anyone EVER really found a set of these gears, and if so, what truck to look for them in?

thanks

You need to find the 1.5 ton chev civy truck rears times 3

A higher reving (newer 270/302 or 235/261 in the case of a chev) engine is easier

well, I was thinking.

I have a chevy (only two axles to contend with) and since I only drive it on paved roads, heck, just fiting the rear end would be easy, IF I can find a civilian application to start looking too!

I seen somehwer the 47 chevy 1.5 civilians had 5.43 gearing.

I alos noticed that a site that has old truck on line manuals that the army made a 1941 4x2 model truck?

These had optional 5.43 gear sets.
