8 Wheel WCD Question

Quick question about a 8 Wheel WCD Chassis: should all axels be floating and have a cam for tensing or should one axle be locked in place with bolts using the provided mounting holes in the VersaBlock. Is there a census on the best setup for VersaBlocks on an 8 wheel chassis?

Thanks in advance!

We are using versa blocks, but machining the gearbox mounts, so that’s fixed. The gearbox is in the front, and each of the 6 other wheels have cam tensioning.
