Re: lowering blocks
Lowering blocks in a truck-arm application allow more drop w/o changing shock travel.

Re: lowering blocks
Thanks ScotI heres what I'm trying to get at. Right now my shocks bottom out when I air out but I still have room for more drop in the notch, so will i still gain drop with the blocks? As long as nothing else is hitting right?

Re: lowering blocks
Yes, more drop should be obtainable because w/lowering blocks the rear will be 2" higher throughout the travel range of the shocks.

Re: lowering blocks
As we lower our trucks we also make the stock shock tend to not work properly. A shock needs to operate within a certain range of travel and be designed to operate within that range so it does its job properly. the shock should be sized to be in its neutral position as one drives down the road under power (kind of like setting the sag on a motorcycle suspension) so with the throttle on the shock should be in the neutral position (same travel up as it has down) . When we lower our trucks we cause our stock shock to not run in this neutral position (it is actually using up some of its travel hence we get a rougher ride and when we dump the air the shock actually becomes the limiting factor in how low the vehicle will go.
The 2" spacer blocks on a trailing arm will get back 2" of travel, but as you continue to lower your truck you may have to go with a shock that has less travel, or redesign the location of your shocks to allow the shock to operate within this neutral point and still travel far enough so that the truck goes as low as possible without bottoming the shock-- when dumping the bags. Seems a little wierd but to lower a truck you must get the height of the shock correct and sometimes this ends up making the shock longer. Kieth |
