I have a Steiger Wildcat 1000.   It has the Raba Axles.  It doesn't have Diff Lock.  Do any of them have a Diff Lock?  Can It be added at all. 
It seems to break loose on one side alot more easily than all 8 wheels slipping a little.  Have any tricks to fix this. 
It has Bias 18.4-38s  If I put on new Radials,  Will I get it to stop power hopping?  Or will it always power hop with Radials?
Thanks
