I don't know if it would be a problem, but I don't know if anyone sells them. You might try calling early classic and ask them, or maybe a board distributor would know. Good Luck

We cary the 2" lowering blocks with U-bolts. We are also working on doing larger drops in the same aluminum blocks, but to make them as cheap as possible we will add aluminim blocks in either 1/2" or 1" increments. I would think that you shouldn't go more than 4 inches using blocks. The 2" kits are 74.95 but we haven't figured out the prices for 2 1/2" or larger yet. WES www.ClassicHeartbeat.com

I'm interested in the same thing, but at $75 for the blocks, and $99 for new coils. Which would be the best route? I've already got 2 1/2" drop spindles in the front.

I have 4 inch drop springs in the rear, and plan on relocating the tank, figure the fuel cell full would prob drop maybe an inch more. If I use drop blocks, am I going to have to notch for the additional drop?
Sorry dream, didnt mean to steal your thread.

No paintpyro, the drop blocks simply drop the trailing arms and the rest of the truck. The rear end does not get close enough to the frame to warrant a notch. I have 3 inch blocks and I still have at least 6 inches until it gets remotely close to the frame.

Sorry, guess I should have read closer. I didnt realize you had drop springs. I would guess that it all depends on how close your rear end is to the frame on wether or not you will have to notch the frame.

The maximum of 2" on blocks is for a safety reason. Any thing over about 2.25" moves the trailing arms down too far and gets the ubolt/nuts below the "scrub" line. Have a flat and you are throwing sparks and grooving the pavement...not cool and hard to drive...also not legal to have anything below the scrub line.

YES, but scrub lines change with wheel diameter. I don't see anything wrong with 3-4" blocks, as long as you are concious of your scrub lines. Any block over 3" usually requires pinion angle correction. Either built into the block or a spacer.

Vendors like Godfather's, etc., have the 3"block kits (actually a set of pre-drilled steel plates that let you drop in increments up to 3", including the U-bolts) for $29.95 last I looked. I have these on my truck, and no way in hell would I pay $74.95 for aluminum blocks! Sorry Wes, but aluminum is for beer cans.

if your running 15" stockers with 70 series tires then you may not want to run anything more than 2" blocks. but for the guys planning big diameter wheels, 18s and 20s it seems to me that you could go up to 3 or 4" on the blocks no problem. im not sure if this is true on coil spring trucks but i know adding tall blocks (3" and up) on leaf spring trucks (such as my old s10s) you get alot for axle wrap when you slam on the gas. |

Early Classic said DO NOT use blocks unless you like replacing u joints a lot. It will change the pinion angle too much.

Well, that would probably work, but someone mentioned calling them to ask, and that's what they told me.

i built my blocks, they are 3 inches tall, if you can find a machine shop they can cut some out for you, the steel is cheap, and if you have access to a large band saw they can me made pretty quick.

I have built lift blocks for my 4wd, just drilled short pcs of 2 1/2" heavy wall square tubing, & capped the ends with the welder. The u bolts can be made to any lenght at your local spring shop, & shouldnt be more than about $25 -30. Can somebody tell me how installing a flat block tween the axle & trail arm will change the pinion angle? crazyL

Just checked Godfather Customs, the 3" kit is $22.00, a 4" kit with angled block is $25.00, including the U-bolts.

Crazy, the more you'd go on this the further out te rear is from factory relitivity tothe tranny. makes the angles change cause the heigt of the rear is all the changes

Have had 3 inch blocks in my truck for 3 years now and have never replaced my old U-joints so i'd say its not hard on them, oh and I have a 1 piece driveshaft in a shortbed, I cannot say what it would do to a 2 piece one in a longbed?

Cool, Adding 2" or 3" lowering blocks would get me about level with the front.
