Default Armada Grand 4WD Modifications

I recently came across an Armada Grand 4WD for sale. I remember Arka mentioned a while back about an idea he had to cut the chasis to shorted the wheelbase to the MM550 wheelbase. This way you get an MM550 XDB with AC/PS/New Generation Chasis/Disc Brakes etc..

I read on the Munnar OTR thread that there was a 540 which was was on a shortened Armada chasis.

I would like to get opinions from the forum about the pros and cons of actually cutting the chasis in the middle to shorten the wheelbase. Is there a way to do it and still maintain the strength of the chasis.

hi, its a good idea if you planning to make it short...the best way you can do is cut the frame in cross style and removing the unwanted size rejoin it by welding it either co2 or argon welding if not you can do regular electric welding with proper rod. then make a c channel plate more than a feet size and fit it from outer side facing inwards and either spot weld it or do nut-bolt or rivit system. i have done couple of jeeps it works fine.

It is possibe to maintain the strength if the welding is done properly with some reinforcing members added. The tricky part ensuring that the 'new' chassis remains true, i.e. perfectly straight. Gas cutting and post weld distortions will make this very diffficult. Even if there is 0.5 degree of error, you will feel the vehicle crab on the road. I would not recommend playing around with the chassis.
Another problem is that Armada Grand/Bolero wheelbase NGCS vehicles have very poor front axle articulation.

You can get disc brakes installed on an older 540 with relative ease. The Classic, MM550XD and Armada are some of the pre-NGCS vehicles with servo assisted disc brakes.

Hi tini,
I feel it is too much of a pain! Why dont you use it as a famility 4wd tourer? Do a good custom paint job, add 31 inch tyres, lower the diff ratio from 4.88 to 5.38. Armada grand has good NVH characterstics so it will be good on-off highway vehicle. You have MM540 Di turbo for your off road duty, make armada grand as a 4wd tourer.

Considering that you are anyway chopping it, and that you already have a 540, why not make it a SWB?? Should be a hoot off road!

I agree with you. Getting the Strength/chasis stiffness will not be a problem. Whereas unless proper fixtures with location pins/features are used before cutting the chasis, it will be a dicey and errors are bound to happen while re- joining

yeah rather than making it into a SWB or like 540/550, make it different family size 4x4.

here is one more option for you. this guy has done a good job and posted these two photos some where in this forum. hope this guy doesnt mind me posting these two photos here for inspiration to others.

hi 4x4addict

please if you buy it don't shorten it,you can make a good offroder having some bling & a little more practical then swb 550.

if you google offroad it will give you results containing more & more long wheel base jeep or you can go to any offroad forum ,you will be surprised to the number of lwb vehicles there..
as you know i have lwb mahindra which i will be doung similar modifications in future.
