Hey guys wanna lower the Blue Heeler 5" front and 6 rear with blocks and notching the frame. i see most spindles they sell are 2 1/2 drop will it be to low? i currently have 3" front and 4" rear if someone has a couple pic's to show it would be helpful. thanks.

CPP's modular spindles are a 2" drop versus most which are 2.5".

Look here to determine if it will be too low,...

the possibility of 5 in the front also depends on what size tires you are running or weather you want to slow down for dips in the road.

A couple of years ago I built a 63 truck. 3 inch springs and 2.5 inch spindles in the front with the same size tire you're running (245/60-15). This is exactly how yours should sit with that combo.

Did you have to trim the a-arms at all? which spindles did you use?

[Tx Firefighter]

No arm trimming required. The front wheels were 7 inches wide with 3.5 inch backspace. Cleared just fine.

Spindles, I ordered from Summit. I ordered CPP spindles from them because they were the cheapest and Summit had them in stock and none of the CPP typical BS that so many people go through. When I got the spindles and opened the box, they were Western brand castings. CPP sells them under their name.

[Blue Heeler]

I want a set of spindles that fit my factory stuff with a 2" or 2-1/2 drop. I don't need all the big brake stuff, big calipers and all the crap that goes with it. i'm running 15x8 rallys is there gonna be a clearence problem or am i good?

[chevy_mike]

Yes, the modular spindles cost more becuase they will allow you to convert to larger brakes if you ever want to. The caliper mount is swapable unlike the cast in styles like Tx Firefigher shows above.

Here's a pic with 15x8, 4.5" BS steel wheels and the clearance between the arm lip and wheel. That extra .5" of other spindles will likely cause clearance issues. Sorry for the blurry pic.

So are you saying the 2.5 drop will rub? I can buy the cpp 2" stuff if thats wut i need, i just dont like buying stuff i cant use then having to return it.

[HouldenCaulfield]

And, you have to convert to disc brakes to run spindles, correct?

[Blue Heeler]

Yeah i'm putting on disc brakes all 69-70 stuff.

[chevy_mike]

From a number of posts, it does seem that 15x8" wheels with 4.5" BS will hit the lip of the lower arm with a 2.5" drop. I personally have not tried so I am only relating to what others have found. If you have less BS or a narrower wheel, 2.5" drop will work fine.

I have my '68 with the 2.5" spindles and have a set of 15x8" rallys I want to use but haven't test fitted them. To be safe, I picked up a pair of 15x7" rallys, just in case.

Thanks for the input ChevyMike, I just need to know cuz i really would hate to do this twice. some shops that i called just want to sell stuff and that would suck to mount all this and find out that it's not gonna work.

Yeah Tex is correct on that...I bought my set up (1960) from CPP and the spindles are from Western... I know for a fact if you are using your OEM rims they will not work!!!

[Calvin66c10]

Somewhat irrelevant but what is the diameter on the hub of those 6 lug disc brakes? Looking to clear a rim with a 3" center hole. thanks

As for the CPP Modular spindle, keep in mind you also have to buy the bracket to adapt your stock brakes to them.

Man what a joke!!! if the 2 1/2 will work then i will buy them. just trying to finish this stage and move on to changing out manual trans to auto trans.

[Clyde65]

OK, so im confused ( no real shock there)

I have 71/72 discs now, I have 15*8 rallyes. do I go with the 2", the 2.5" or the modular spindles? I do not want to mess up my a-arms or my rallyes.

[Pro Performance]

From the look of the picture above, you will want to go with a 2" spindle, cause the 2.5" will put the a-arm right against the wheel.

[Blue Heeler]

well for what it's worth just got off the phone with CPP and they did say 2 1/2 drop spindle will work with an after market wheel but not with stock rim. i grinded the guy for atleast 15 minutes on this and he assured me there is no problem part#CP4S2 thats using you stock stuff tie-rod ends 68-70 rotors and stock calipers.
