Another good source for Roller Spring Perches.....

[thehueypilot]

I just installed a pair of roller spring perches. I tested them at the NMRA last weekend in Memphis, TN. They do free up the front end and even the squeaks are now gone. The company is: Paris Machine & Fabricating (731) 243-4951 and ask for Jerry. I paid $225.00 plus shipping.

Look good. Are they bent in the middle of the tubing to let you put the nut on ? I see you hvae the nut on, but they don't look bent in the tubing.

By "freeing" up the front do you mean reduced understeer? What did it do to your lap times?

The tube is not bent, but I had no problems putting the nuts on. The shaft was machined (notched) down slightly 3/4" to accept a smaller OD bearing so it sits against this step (positive stop). The outer tube is machined with a step to hold the bearing in place. From what I can tell it is a good solid design so far I have 6 hard launches on them.

I only drag race. It let the front end move up quicker/smoother to help transfer the weight to the rear.

did you get a better 60' time?

 

[thehueypilot]

No, but I think that was because my torque convertor is giving up on me. It is going to be replaced with a 3.5k stall by this weekend.

Any particular reason you didn't go with Opentrackers at about $169 ? (when I bought them)
Does this style work better for the drags?

Curiosity only.

I thought Cobra Automotive was the only retail source and they wanted $274.95 for a set. As far as I know they are the same as far as operation, just a slightly different design.

where can you get the opentrackers? What I found was how to make them yourself.

I like the design of these are the roller bearings better than the bronze bushings? I also noticed that there was no grease fittings!

Nothing new, it'll be the same parts I've been working on for the past few years. We'll be starting with perches and upper arms.

its a sealed bearing, why would you need grease fittings. The are better than the bronze bushings because they move more smoothly, and roller bearings last longer than bronze bushings. Plus they won't squeak or get contaminated with dirt.

I make the perches with sealed roller berings because I didn't want the issue of greasing and rebuilding and I thought the bearings would be a bit smoother. The bearings can be replaced with some effort. The bronze bushing is stronger from a weight rating standpoint.

I made a set of both the bronze bushing ones

And the roller bearing ones

The bronze bushing saddles were actually more work to make. As john said I'm sure they're stronger but I doubt the roller bearing saddles would ever fail even under hard racing conditions.
I'm using the roller bearing saddles on my car and the bronze ines actually ended up in a '65 coupe vintage racer.

I think the design is a good change then. Is there anyone else doing these and if so who and how much( have to watch my pennies these days).
