Axle Risers

Originally posted by jdsanders Thanks for the info on 15" tires and pics.  That is great info that switching from 14" to 15" tires will only raise my 2010 RP-174 only one inch.  I guess that would help but I prefer to raise it 2"-3". I understand the risers raise it 4".  What about switching to 16" tires and raising the fenders?  You do understand I am trying to raise the axle too?

Not quite sure why you are trying to raise the axle as well.There is plenty of clearance given the fact that there is no differential pumpkin hanging down in the center as with a rear axle of a typical Truck.As the wheels traverse a bump,the axle rises with it.

Unless of course one where to straddle a 8" boulder in the middle of the road,that would be a problem.But even the worst of roads that is unlikely and speeds traversing would be very slow.

The 4" axle risers,better to be called "body" risers" work well on steep inclines keeping the rear stabilizer jacks from leaving their mark in the asphalt.

The 205/75/15 tires are 1" larger in diameter then the stock 205/75/14 tires effectively gaining 1/2" of axle clearance to the ground (half the diameter gain) Raising the Pod 4" with the available risers is fine.The extra 2 to 3 inches that you would like would require custom fabricated riser blocks and unlikely to have R&D or any engineering or testing.

In my opinion not worth the extra effort,money or risk for an inch or so difference.

A 16" tire for an additional 1/2" axle clearance ,over a 15",is certainly doable.Quite a large and heavy tire though.The added weight and rolling inertia may work the brakes a little harder.

Jerry, you might consider this, travel trailers have been running on the tires and axel config for years and I personally have not heard of very many axel related problems related to clearance .
