Suspension & disc conversion parts list

[NWD02]

Hey guys I recently completed the front suspension rebuild. In the process I converted to disc brakes and replaced all suspension parts. I wanted to forward you guys the part numbers just in case it might help someone on the forum. I bought all the parts from the local O’Reilly Auto Parts so you could even order parts online though them. I bought drop spindles and springs through Mike’s Bump and Grind Garage in Webster, TX, he has a website.

Here are the parts and part numbers I used for the conversion:

2 ½ inch drop McGaughy Spindles
1 inch drop McGaughy Springs

New front suspension parts:

Pitman arm K6131 39.99
Idler arm K6096 15.99
Ball joint (2) K6024 14.39 each 28.78 pair
Ball joint (2) K6023 12.47 each 24.94 pair
Tie rod end (2) ES370R 11.51 each 23.02 pair
Tie rod end (2) ES350L 11.51 each 23.02 pair
Control arm shaft (2) K6098 28.79 each 57.58 pair
Control arm shaft (2) K6147 33.59 each 67.18 pair
*** I used the low-end house brand, but all of them had grease fittings. I was told by the employee, sometimes the same part numbers of the low-end parts will or will not have the fittings, and might be slightly different in appearance. So, if you choose to go low-end, I would suggest buying from the store not online. Check each part to make sure they match, (Ex: ball joints, tie rod ends) and have the grease fittings.*** I did not buy sleeves from either place. I also returned the outer tie rod ends and went with newer model ones because of the sleeves I ordered from CPP. I did have to drill out the hole on the spindle for the tie rod end.***

Disc Brake conversion parts:

Rotor (2) 81-60258 29.39 each 58.78 pair
Brake caliper 18-4038 24.69
Brake caliper 18-4037 24.69
Disc pad set EC52 25.11
Wheel seal (2) 8871 1.69 each 3.38 pair
Brake hose (2) BH380712 20.10 each 40.20 pair
Dust cap (2) 13977 3.59 each 7.18 pair
Spindle nut (2) 04993 4.99 each 9.98 pair
Bearing (2) A3 7.49 each 14.98 pair
Bearing (2) A6 6.91 each 13.82 pair
*** verify bearing part numbers before you buy. I remember I had an issue with the inner, but I think it might have just been the kid working there gave me the wrong one but had charged me for the correct one.***

Looks like a good investment in safety.... How did you enlarge the tapered hole in the spindle arm? I hope you didn't drill a straight hole in it.....

What year truck did you install the parts on? McGaughy sells spindles for 63-70 trucks and the 71-72 trucks. I thought the difference between the two of these was smaller tie rod ends and ball joints for the 63-70 and bigger for the 71-72. Are the newer model parts you bought even bigger than those?

Also, what size rotors did you go with? Are the calipers single or dual piston?

I bought the spindles for 63-70. The tie rod ends I used were 73 newer, I think.

I used the stock, 71-72, calipers. They are single piston and the roters are the stock 71-72, 1.25 inch.

So to sum it up you used 63-70 style spindles and 71-72 calipers/disks with the prior listed suspension components to make it all work? Are the 71-72 disks 6 lugs? Do you know if there is a 5 lug disk that will fit this application? Thanks!

tehy are 5 lug. GM swapped to 5 lug when they went to disk brakes

Will the 71 spindles work on a 68?

[Classic Heartbeat]

71-72 Spindles will work if you change the ball joints and tie rod ends. WES

I think I paid $200 for them. Mikes Bump and Grind Garage, he's on the site under venders. They're really awesome, prices are great!!!
