welding spring perch to frame

[Bill Holley]

a fella on hot rodders site is building a bucket.. yes i mentioned coming here.
he's ready to weld the spring perch bracket to front of frame and needing to know the angle.. i know it's not straight with from but don't recall the angle
he's using a 4" drop.

On my CCR chassis, the perch is centered and parallel to the frame. I have pics from the plans I used if someone wants to see.

Well . . . I am no suspension expert, but - if you think about how the spring will function, it does need to be parallel to the ground, front-to-back. This will only be a problem for those buckets which have a rather severe rake, back-to-front. Most of us have a little "rubber rake" with bigger tires in the rear, but some angle is not usually a problem. Just my opinion (and observation of many buckets during the past years!)

On mine, if the bare frame were laying on the floor, the spring mounting surface on the perch would angle up towards the front by 3 degrees. This is to compensate for the 3 degree rake built into my chassis set up. My front spring is square/perpendicular to the ground with the car fully assembled.

tks KC. i thought there was a rake but couldn't think of what it was.. tks.

I have a CCR frame on my T and the front perch is parallel to the main frame. I'm also using a 4" drop.

The placement of the perch is important, but NOT critical. It is probably safe to install on line with the frame rails. Miss alignment can be corrected by the spring pins. Cecil

When you stop to think about it, the set-up of the spring perch isn't the major factor here. Most companies that make T-bucket frames like CCR set the spring perch inline with the main frame rails because the whole front end pivots on the spring axle brackets and its the radius rods or four bar set-up that determines the angle of your front end, not the spring perch angle. To set the angle of your axle is done by the radius rods, not the spring perch. No matter what angle you put your spring perch at, it all boils down to making your adjustments for the axle angle by the radius rods or four bar set-up, which ever one you have. I know when I built my frame and it came time to adjust my axle, I didn't even touch my springs. If you want to put an angle to the spring perch, go ahead because it really doesn't matter all that much because that's not were the adjustments to the axle comes from. But that's only my opinion
