rear trailing arm suspension
so my 69 came with the trailing arm rear suspension and im just wondering, for those who are running with theirs still, how they like it.
debating whether to just buy an aftermarket trailing arm kit or should i go all out with the triangulated 4link. the truck will be a street legal drag truck, trailered to the track but able to drive to local events and shows. thanks, Kyle N. |

Re: rear trailing arm suspension
Most the time your going to get a "they work great with little modifacation"
There will be a few others that say go 4 link. Personally I run the factory arms as do a few of the even faster guys. They can work very well with next to nothing for mods.

Re: rear trailing arm suspension
In the videos and pictures posted I had:
Put a different spring in it with a block to lower it Moved the upper mounting point for the rear shock (only to accomidate the slightly longer shock) Made adjustable mounts for the front eye of the control arm: http://67-72chevytrucks.com/vboard/s...highlight=rear Since then I have: Made a 1 3/4" x .120 wall antiroll bar eliminating the factory one that was on it Added spring pockets to the rear control arms so I could cut my springs further or allow me to use a non pigtail spring if I choose to swap it out. Still need to swap the rubber bushing in the front eyelet for a set of polly ones I have. Some weld the center of the arms together. I didn't.

Re: rear trailing arm suspension
excellent, thanks a ton man, that link is very helpful with the pictures. im definitly going to look into doing something like that with the adjustability.
How are you finding that set-up? Is it helping you hook up better? I see from your videos you got some tire lift up front so your getting some good traction to the back on the launch it looks like. |

Re: rear trailing arm suspension
I have stock trailering arms. Planning on changing shocks and springs later. Best 60' so far has been a 1.58 on my set up, but now my slicks are about worn out. Super73 knows his stuff when it comes to suspension...

Re: rear trailing arm suspension
I run a 4.30 gear and 33 x 10.5w tire. I would run more gear if I didn't have a bottle.

Re: rear trailing arm suspension
cool man, i just went through some of your build thread there and im just curious how you like your front suspension? i hear it can be a pain getting the steering lined up and workin proper. and another question on what exactly the rear suspension has done to it?
