by EvilToywarz Mon May 18, 2015 4:39 pmHas anyone removed a leaf from a 2nd gen chevy van? I am thinking about doing that, but was not sure how the mono will be? Since there is only two springs per spring pack on the 2nd gens. I had one set dearched and that really did not lower it much, waste of money. I have another set of stock springs that I want to try this on.... any input would be great..... not sure why there is not more of fellow vanners lowering their rigs. These vans sit too high to begin with...imo..

I hear that. I saw a guy who had his front lowered, and it looked MEAN. I think over on the VCVC website. I'll drop him a line and see how he did it.

My 69 g10/108 has three leafs in front...the SPID tag shows HD Springs as an option......I looked up shock lengths on Monroe and the stock shock is fully extended at 19.5 inches, yet my van is sitting static at a 20.5 inch shock length, so it's hard to say whats been done to this van over 46 years........
I am considering making a set of flip cradles to create a 5" drop on mine..... I have also found that Monroe MA 812 air shocks have the right ends to fit the front of these vans and travel from 12.75 inches to 20.75, which will give me about three inches of travel to work with.....
You could TRY taking out a leaf, but the concern for me would be that your caster could go seriously negative during braking and make the van want to go anywhere but straight and would probably present itself as an uncontrollable side-to-side shimmy. Caster, as you probably know, is the alignment angle that you adjust by using wedges between the spring and axle. Rolling the axle forward, like results from a steep forward rake, is to add negative caster and will make a vehicle wander rather than track straight. When you step on the brakes, any spring-wrap will do the same, but on an oscillating basis as the spring reacts. Positive caster, on the other hand is what make a vehicle directionally stable and want to go straight down the road......I'm not saying don't do this, I'm just saying to be careful and be able to undo it if it doesnt work out...... Another way to negate the spring wrap effect on braking might to add a locator bar (think four-link with the springs as the bottom bars) to each side
