My front end is a little higher than the rear after a 2 inch leveling kit. Do I need longer shocks if I raise the rear end? I'm going to get Bilstien shocks will the 5100's fix this or do I even need them and can I just go with the HD's. Thanks

 

I talked to Autospring and I'm getting the 3 inch rear block to replace the 1.5 stock block and I will not have to get longer shocks. Sorry to waste a thread.

 

Yes, with a lift kit in the rear you will need longer shocks.

As for your question between the 5100 and the HD's...5100's and HD's are the exact same shock. The only differences between the two shocks is the 5100's are zinc coated and they are longer for lifted applications. The internals, construction, valving, etc, etc, is identical.

Thanks Galaxy. The guy at Autospring and on there web-site told me I would'nt have to get different shocks he said the stock shocks would work you have 6 inches of clearence with the stock shocks.

 

I've got a AAL on mine for almost 3" lift and I'm still on stock shocks. I don't like them very much, but it works.

 

What ever you guys are comfortable with. 1 1/2" would most likely never ever ever matter. Any more and it's pushing my comfort level. I will admit though how often does the rear suspension ever see full extension?? That's when it would matter though.

If you read the write up on the link I provided, a lifted truck with stock shocks ends up in the position of the shock being too short. The shock would become fully extended before the suspension reached its fully extend point and stop when it hits a bump stop as it's designed to do. The shock would be acting like a limiting strap preventing the suspension from traveling its fully desined travel limit to the bump stop...and things will break if the force is great enough.

Good luck.
