So you've got a Mustang II front suspension and
want to put coil-overs on it. Today we're going to walk you through how.
Hi everyone I'm Tim and I'm Trevor. Today we're going to walk you through
the Mustang II coil-over fitment option and the term Mustang II is kind of widely used.
It can refer to a stock front end off a Mustang II vehicle that's been
removed from that vehicle then graft into your your street rod or your hot rod and
there's also other after-market Mustang II front ends where they use that term.
There's differences between them and the important thing is determine which one you have so you can
select the right product. Yeah or keep in mind too maybe even have a true 74 to 78 Mustang which was
the Mustang II then and and a lot of those front ends got torn off the cars because they did have a
lot of inherent advantages to them uh and features as well. So you know it's a long short arm design
with coil springs it had a rack and pinion steering and disc brakes as well. So it for
the hot rodder market it was a popular swap that that people swap these front ends into
just about anything. Right. Yeah well I guess we'll start with that one first which would be
your stock type front end Mustang II. Now QA1 we offer a direct fit coil-over system for a factory
height and the two inches lower than stock Mustang II front end and that is going to mount
uh in the lower shock mount with the through bolt just into your factory control arm. It uses our
tapered spring design where the bottom part of the spring sits on the shock on the bottom and
then the top of the spring and top of the shock fit up into the factory spring and shock mount.
So if you have a factory Mustang II front end all the factory components are compatible components
this should be a bolt-in fitment to work from your factory height to about two inches lower than
than factory. Yeah so that's gonna be a real easy part swap there just a direct bolt-in system. But
like we mentioned there's a number of aftermarket Mustang II front ends out there so in determining
the proper fit on a coil-over for an aftermarket front end we definitely have to be aware of
some things there oftentimes that front end is designed with a little bit different geometry
the shock placement may be different the ride height that is needed out of
it may be quite different than the off the shelf Mustang II setup. And for that reason
we often have to take measurements and get weights on the vehicle to determine the appropriate
shock and spring setup to get the intended height and ride quality we're looking for. So yeah if you
could Tim why don't you cover some some of the requirements there to get the right setup in an
aftermarket suspension. Sure. So some aftermarket suspensions they'll still use this type of
configuration where they use a tapered spring. The difference can be that they might move the
the upper shock mount and spring mount. They might move that to get maybe more travel in the shock or
maybe a wider range of height adjustment. So if you have that type of of spring and shock setup
it's important to get your vehicle sitting at the ride height that you want it to sit at
and then simply pull a measurement from the top shock mount to the bottom shock mount and
you know we can help you determine what length you need to fit inside that
in that mounting configuration. Some other aftermarket you know they still use the
term Mustang II as a term but it really isn't using any Mustang II actual parts.
So it's all fabricated aftermarket components the shock mounting is different it's just basically a
rack and pinion short long arm type front end. It might use Mustang II spindles uh and brakes
but they can mount with an eyelet configuration top and bottom and you know that's obviously
significantly different than this type of setup. So this usually the Mustang II
aftermarket front ends you see with this type of setup. The shock and spring is closer to the wheel
you have a longer travel shock in there usually and then it uses a smaller two and a half inch
inside diameter spring. And that is similar to to fit that it's similar to like we do with this one
you're just taking your measurement from center of eyelet to center of eyelet with the vehicle
sitting on the ground at ride height to determine what length you need and then of course you have
different spring rate options which we have a way of figuring that out just based off the front end
weight of the vehicle. {Potentially if you've got a really different you know style of Mustang II
front suspension we may also ask you to get some measurements off the lower control arm
oftentimes that will change the lever ratio of that control arm which then requires
a different spring rate for a given front end weight so yeah there can be some some definite
differences between the aftermarket and and the stock suspensions there. So yeah again key things
shock length at ride height is probably the biggest one and if you've got a style like this
yeah we're going to measure from this center down here up to the mounting surface there
oftentimes we'll use like a GM based front shock then and oftentimes these will have a T-bar style
lower control arm mount. But what we got then is conversion parts to adapt that lower mount
to a more you know Mustang II-esque lower mounting system so. Yep and then another
thing to note is the the through bolt style on the lower control arm a factory Mustang II is 7/16
and the a lot of the aftermarket stuff is half inch in size. So you want to take a
close look at that and make sure you get the right bolt size for your lower mount because
too small of a bolt too big of an eyelet or you know other way around it won't bolt up so
that's also something to note. So just a few things to kind of look at when
you're trying to fit your your Mustang II coil-overs on and select the right product.
So now that we've discussed the various shock lengths needed the different mounting points
and the different configurations of both the Mustang II front end and aftermarket versions
of it we've got great information available on our website to determine best shock and spring
combinations for your particular setup. And as always too if you've got any questions on that
process please reach out to us on our tech line and we appreciate you watching the video today.
