    Hi everyone

    I have been wanting to lower my 51 P/U for sometime now, but what's the cheapest way to go about it? I'm a student on a budget so saving money is important. Is there a vehicle that has a suspension that will bolt to my 51.

    Any suggestions?

    Chevy half-tons from '73 to '87 are supposed to be a bolt-on IFS replacement for your straight axle. This will lower the truck some, and give you much better handling. Lowering blocks work for the rear end, but if you find your donor truck you probably will want to take the rear axle from that so the bolt pattern matches the front wheels.

    I haven't done either to my truck *yet*, but I've been doing lots of reading on doing it cheap AND safe (not mutually exclusive after all). This sounds to me like the best option for the buck.

    I'm not an engineer, but it seems to me monoleaf springs on an otherwise stock AD truck would increase the body roll due to reduced spring rate, and you wouldn't be able to corner at all. These rigs are all steel, and weigh a couple tons empty (mine is a 3.5 ton panel, GVW 8800 lbs). Unless you NEVER carry any weight and add heavy swaybars, the monoleaf springs will break the first time you swerve around a dog in the road. I'm sure you can add hardware to compensate, but that will push the cost up. Again, I'm not an engineer and I may be off-base, but I prefer to err on the side of safety.

    If the objective is to lower the truck a few inches, lowering blocks can be installed on all four corners, and the only loss will be spring travel (not an issue if the truck is just for cruising). New shocks would be a good idea, since you're changing the height and the throw; and depending on how low you go, you'll need to alter the steering linkage to keep it from binding. If you're trying to get the nose in the weeds, you need to junk the straight axle and find an IFS clip to make it safe.
