Steering Box Mods?
I have a 67 C-10 long bed with power steering. Is there anything I can do to get it to turn better? It is easier to turn a dually than my LB. Any help is appreciated. Thanks

Re: Steering Box Mods?
I put a 73 up box in my 72. It is 3.5 turns lock to lock instead of 4.5 It feels much better. You will need to use the pitman arm for the 67. You might double check to make sure but as long as the 67-72 boxes are the same this mod will work for you too.

Re: Steering Box Mods?
As far as I know OhOneWS6 is right. I remember something about swapping "car" guts for "truck" guts is viable but not needed. If it means anything my BMW is 3.25 LTL and is very quick. Swap in a later box and see what you think. I have a manual 67 and hate it! Its the top thing I dont like about my truck and cant wait till I get something better. I think mine is over 5 LTL!! I dread parking lots and tight manuevers!

Re: Steering Box Mods?
Just wanted to clarify what I was trying to say. I know 71-72 will swap with the 73-86 boxes (73-77 is a direct bolt on, 78-86 is metric o-ring fittings. There are a couple of ways to make the 78-86 boxes work.) I am not sure that 67 is the same as 72. If 67 is the same as 72 then the later box will work for you. Hopefully that makes sense.

Re: Steering Box Mods?
67 was a ram assist.If there is a hydralic ram mounted between the frame and center link then that's what you got.If I had that I would first make sure the front suspension was in good shape.Then I would swap the factory manual box out for a 73 up box.That should give you factory steering comparable to a 73 long bed.The lock to lock will be the 3 1/2 instead of the 4 1/2 turns.I'm not sure about the pressure/volume of the pump.Hopefully someone will chime in with that info.
Second choice is to rebuild the ram assist.Some have done it but IIRC parts is scarce.

Re: Steering Box Mods?
Quick ratio itegral gears are 75 up. The 67 chassis is not set up for the integral power rteering gear. Your frame needs to be dimpled for the gear to bolt on and your radiator core support mount needs to be notched. Some people have bolted the gears on by using spacers, including me, however this will make your truck unconfortible to drive. Spacing the gear off the frame will make your gear run off center making your steering twitchy. WES

Re: Steering Box Mods?
Thanks Wes,I was sure I was forgetting something.He will also need to use the pitman arm that works with the PS box and is the length for a 67.IIRC a 68 Pitman arm would work but specify a PS one since the shaft is different from a manual.
There should be a ton of info if you do a search.Seems like there is a FAQ on it also.

Re: Steering Box Mods?
Only word of caution- these trucks are very top heavy - if you turn them to fast they tend to roll over on thier top.
When I had my gearbox rebuilt the sped it up but not as fast as they could go for the above reason - it was thier suggestion and I think a wise one

If it's the steering is too stiff and it has the ram assist, you can go to the gearbox as mentioned above. If it's the radius turning of the truck, there probably isn't too much you can do. The gearbox has lock to lock mechanism that may be different between different years, but you probably won't notice a significant change there. I have tried two different gear ratios on my 68 -a quick ratio 2.5 lock to lock and a slower one at (IIRC) about 3.5 lock to lock. Both were about the same on the turning radius of the truck but I prefer the 3.5 one. It seems a little more stable on the highway. |

Re: Steering Box Mods?
What didn't you like about the 2.5 vs. 3.5? I have stock non PS on my 67 and NEED a change to make it a daily driver.

Re: Steering Box Mods?
Thank you everyone. It looks like I'm going to have to live with the factory box.
The problem I have is not being able to turn as sharply as I would like. Sometimes it take two tries to get into a parking space. Again, thank you all for your input.
