Green 2" Spring Is An 1128 Pound Spring With 1/2" Travel. Have An Afco Mini 4 1/2" Long Spring 1050 Pounds With 1 3/4" Travel. I Have 7* Pinion. Half An Inch Does Not Seem Like Much Travel, But Will 1 3/4" Of Travel Take The Rotation Of The Rear End To Far Around And Go To Far Past 0* Pinion? Would That 1128 Lb. 2" Spring Be The Same As A 1128 Lb. 4 1/2" Spring?

Thanks

I wouldn't use it because the spring is just a dampener that bottoms out under throttle. The major thing that changes pinion angle on a rayburn is chassis hike, not the pullbar. By adding a spring with more travel but the same rate it will still coil bind but will travel alot farther to do it(more pinion angle).

Thanks yes both 1128# spring would be the same rate die springs are designed to trave 25% of ther overall length.we used the 4 1/2" spring just to get a few more nights out of them the 2" springs are only good for 2 or 3 nights.
