Ask Strange why they messed with the kingpin angle on their dragster spindles

If you are building a new car and going to use a tri-pod style front end, there are no problems
If you are replacing older spindles on an existing axle with the new Strange's, they will have 1* neg camber, EVERY spindle ever made before these were 8* and the new Stranges are 7*

Wow, this is too bad, thanks for the heads up Bruce. The 8° Strange spindles will became collectible items. What were they thinking??

If you're building a new axle or replacing the spindle bosses as well as the spindles you'll have no problems.

The work to change the spindle bosses is more work than just building a new axle, Anything CAN be done, this is just a heads up to those replacing existing spindles or buying a pre-made axle, that the new Strange units have different dimentions then what has been the industry standard for the last 50 years.

There's been a couple different spindle boss heights as well between a couple of the manufacturers as well.

Yes there are and M/W wants you to use a bronze thrust washer (comes with) to make up the gap.

I talked to Dimitri from Strange today and he said that when they did their spindles they simply copied the existing units. I just set one of my Strange units up in the lathe chuck and measured the king pin angle relative to the lathe bed and it is 8 degrees. To make sure I was doing it right I put a McKinney spindle up next and it measured the same. Interesting the P-S Machine spindles off my Don Long car measure in at 8.5+ degrees but they had the bushes reamed after they were chromed back in 1969 and that may be where the discrepancy comes from.
I had made a new axle for one of my customers this week and cut the notch to the same angle as I always did for the Stiletto spindles (and more recent Strange units) and the boss fit perfectly with the spindles in my Mark William style fixture.

Bad QC at Strange then

SPE  8.5
M/W  8.5
P&S 8.5
OEM Anglia  8.5
Strange   7.5

all measured the same way off the chuck in my lathe with a digital degree readout

Bruce... have you called Strange about this??

I did, said they would get back to me, that was 3 months ago, but figured I was the only one that brought it up "we sold hundreds of these and no problems", not many shops build front axles like I do anymore.

They don't? How do they get made?

Most shops build tri-pod front ends. you stick the spindles in a fixture on the jig and you fit the tubes to the spindle boss , so whatever degree the kingpin is does not have an effect on the build. I stick the bent front axle tube on the mill and tilt the head and bore the tube to press in the bosses, tack them in place and cut the excess off to finnish welding. Now before I can build an axle for someone , I need to ask what/whose spindles are you going to use.

36" wide  2" offset  5" drop  SPE spindles @8*

Nice setup Bruce. Now I know where to go if need one.

The 3 sets of Strange spindles I have in stock all measure 8 degree's. Kind of unfair to say how most guys build axles, unless you've worked in most guys shops.

If you have 20+ shops building S/C dragsters and 3 or 4 building tube axles for Nos cars, that would qualify as most.
 Again back to my earlier post, I have at my shop P&S, SPE, M/W, OEM Anglia and Strange spindles, using the same fixture and same digital angle finder to measure within the same 15 minute time period and the Strange is the only one that is different by 1*. I install a new set of Strange spindles on a fixtured  axle and get Negitive camber, swap out with a set of SPE's and I get .5 deg positive camber(how I designed it).
 The Strange spindles are nice parts and will use them upon request, I just have to know about it first. The other thing that bugs me about them is that they turn down the OD of the spindle boss to an abscure dimention and cannot use my hole saw to get a nice fit, probably have to get one custom ground just for those.
