Today's update, I'm now fully into building these parts in batches. I've got stacks of tubes cut, bins of bushing sleevs cut, spacers cut and turned and next up is bending stacks of tubes. Just got a foot valve for my bender to make it even easier. While I'm bending I'm also setting the horizontal bandsaw to cut tubes. It's saving me time so now I'm reducing lead times and that's always a good thing.

LEAD TIMES The website individual item pages may have a lead time on an item. I haven't changed them all yet but currently we are at 3 to 4 weeks on most control arms. I'm working that down as you read this by doing these things in larger batches. So I will add the current lead time to this blog and update it when it changes. It will be in weeks until I get down to less than a week. Let me know if you have questions, thanks and peace

**** CURRENT LEAD TIMES 3 TO 4 WEEKS ON MOST ITEMS ****


I've launched a YouTube channel for the shop. You can find it here:
https://www.youtube.com/@chassispartsonline

I'll be adding content starting with what comes in the box when you order my control arms or crossmember kits. I've already done one for the lower arms for bags and one for the lower arms for struts/coilovers. It basically explains what each spacer, washer and bolt is in the box, how the balljoint goes and how the bushings go. If you have anything you would like to see please let me know. Peace

Welcome to Chassis Parts Online. We manufacture suspension parts for classic trucks and some other vehicles we have taken an interest in. Our main focus is the F-100 and specifically the popular Crown Vic Subframe swap. In fact I also own the Crown Vic Subframe Swap page on Facebook. I started that page way back in 2014. I did so with the intention of building parts for them at some point. Now I'm doing that as well as parts for one of the things I have done since the 80s and that's minitruck suspension. Specifically air bags and the suspension needed to run air bags.Take a look around this basic shop website. Let me know if you need anything. Thanks

Our tube arms are made with DOM tube and laser cut steel plates. Cold rolled steel when we can. We make all our bushing sleeves from DOM as well. We turn all our bushings on a lathe in our own shop. We use only Energy Suspension graphite impregnated polyurethane bushings. They are the absolute best there are available. The graphite impregnated means they do not require grease and will not squeak. Most shops use Daystar or Prothane poly bushings that do requre grease and will squeak when there is none and will also become spongy over time. Some shops will use a Delrin bushing which is hard almost like plastic. You don't want that in a street driven vehicle for the same reason you don't want heim joints in your suspension. They transmit vibrations into the chassis. Like having solid motor mounts. No need for it when you can have the best bushings available. They are also easy for you to get thru any dealer that sells Energy Suspension.

Our control arms will use the factory style balljoint for that vehicle in most cases. If not it will be made for another common vehicle. There are no special order balljoints. We prefer balljoints with a metal ring holding the boot which helps keep the grease in where it should be. We do offer uniballs (spherical bearings) on some applications. By that I mean for example. If you need control arms for a 99-06, 07-13, 14-19 or 2020 up GM half ton truck those all have the same basic press in small balljoint. However to make custom arms with a better balljoint thats more heavy duty, has more degrees of travel like for an air ride truck and also bolts in to make it simple I would use the K6136 which is made for 73-87 GM trucks. Same taper and length and they bolt in.

Or for a 97-03 F-150 you can use a K6292 which fits an 88-98 GM fullsize truck.

I also know lots of other ones that are kind of obscure like S-10 bolt in balljoints fit Toyota and Mazda spindles. Nissan Hardbody upper and lower balljoints fit Mitsubishi spindles.

Chrysler style screw in K772 fit many uppper spindles like Mustang II etc. I've gained that knowledge from building tube arms for lowered and bagged trucks since the early 90s.

Now I've turned my attention to early Ford trucks. I plan to make lots of other parts like 100% bolt in 4 links for using the 9 inch, the 03-11 Crown Vic rear, the 02 and earlier Crown Vic rear or the 90s Explorer rear which is also an 8.8 with limited slip and 3.73:1

Plus panhard bars, watts links and step notches. I also build custom tube chassis in my home shop. I will offer a full F-100 chassis at some point. One you can afford by the way.



As some of you know I used to make tube arms for all kinds of trucks for bags. I've made hundreds of sets of arms over the years. Our plan is to add more and more tube arms to our page as we develop them. Over the last few years while I was out of the control arm game but doing fab work at one shop or another I've made arms for a 73-87 GM fullsize, an 88-98 GM fullsize, an S-10, a Mazda B2200 on bags, an Isuzu on bags, an 07-13 GM fullsize on bags and many 4 links, watts links etc. All those items will be items we make as we move forward.
