Leaf Springs Rating Doesn"t add Up

Hello everyone,

Problem that I am having is OEM leaf springs rating. My Bounder rear has a GAWR of 11,000# and the OEM leaf spring are rated at 3955# ea/7910#pr. I thought the leaf spring's rating should be equal or greater than the RV's GAWR, am I missing something here?

Thanks all for your help.

Obviously the combined spring rating has to equal or exceed the total axle rating. Ditto for the tire ratings. How did you determine the spring rating? And the number of springs in the axle? I would have guessed at least two leafs per side, for a total of 4. Or maybe even 6?

Hi Gary:

Here's the link with the specs...It was cross reference with the dealer's OEM#. This is a non-stock item at the dealership. 1993-1999 Chevy / GMC P30/3500 Motorhome Chassis - Leaf Spring (Rear - 4/2PD Leaves) - 22-937 | $273.84

The beast is a 96 chevy P-Chassis 4 disc. It seem their is a 30%=/- deficiency. Even with the extra leaf which adds 1000# per side will not equal or exceed the gross axle rating of 11K. The people at SDtrucksprings tells me the spring are always less than the gross axle rating. This just doesn"t add up. BTW~ the tire rating exceeds the axle rating with no problem. Thanks

Not sure about your concerns, remember the weight rating is for the whole vehicle, but the springs only hold up the frame and body. The rear axle, drive shaft, brakes, 4 tires and wheels, etc. aren't on the springs, they're on the road.

I should have stated that I'm replacing my rear leaf springs and the OEM cross reference came up with OEM replacements spring capacty of 7,910#. The rear axle gross rating on the beast is 11,000#.

I was concern why the gross axle rating (11K#) did not equal or exceed the spring capacty (7,910#), but as you stated makes sense. Does all that stuff connect to the axle weights 3,000#?
