When going over bumps in my TR4 I have quite a rattle from the right rear
area of my car.  I have poked around by the axle, and thought I have fixed
the problem a couple of times.  I have replaced the springs and refilled the
Armstrong shocks.  I have poked around. While looking through my Moss
catalog I noticed the kits for replacing the Armstrong shocks with these
brackets that you could mount shock absorbers to. But the kits are NLS.  No
Longer Supplied.  I was wondering why the kits  were discontinued.  It could
have been that they caused damage to the frame, or just didn't work.  I was
hoping somebody had any first-hand knowledge or experience on this topic
that they could discuss. I wonder if the racing group all have custom and
proprietary set ups.

>=20
> There are at least three styles of tube shock conversions for the TR6 and I=
 assume the 4A.  The one with three triangular brackets that go through the b=
ody (likely the one you looked at from Moss), A bracket that bolts to the bo=
dy with no frame attachment, and a single plate bracket that bolts to the le=
ver shock mount.
>=20
> Also watch for feedback on people that just get the lever shocks rebuilt w=
ith a heavy duty rebuild.  If I was starting over, that is probably what I w=
ould do.
>=20
> A sample of the three plate design at Moss is 670-128 - see https://mossmo=
tors.com/rear-tube-shock-conversion-kits - the Monroe shock version for the 4=
A is available.  They have an article at http://www.mossmotoring.com/tr6-tub=
e-shock-conversion/  It looks like a sturdy design, but takes significant ef=
fort to install.  Read the instructions from their website.
>=20
> I do not recommend the bracket that just bolts to the body without a frame=
 attachments.
>=20
> I used the single plate version because it was much easier, but this desig=
n leads to flexing of the frame cross member and cracking of the frame, incl=
uding mine.  See the 0091, 2217, and 2218 images attached of other people's c=
ars discovered at a local club tech clinic.  If you have this design, I reco=
mmend you check the frame cross member regularly.  If you have the rear spri=
ng out for any reason, run the trailing arm through its full range of motion=
 and you will probably see the top of the shock mount move front to rear.
>=20
> After having my frame cracks welded, I built a new version of the single p=
late design available from some vendors.  I extended the top mount for the s=
hock back about two inches and added two braces.  One is a length of 1" angl=
e iron that goes between the two shock mounts near the top of the bracket, j=
ust below the body to side to side stability.  The other is the more importa=
nt addition and goes from the top of the shock bracket rearward to the frame=
 at about a 45 deg angle.  This one stops any front to rear motion of the sh=
ock bracket.  Unfortunately the car isn't easily accessible right now and I c=
an't find my pictures.
>=20
> Below is an item I wrote 20 years ago or so.  The 5-6025 kit is the single=
 plate design that in my opinion needs at least the added bracket from the t=
op of the shock mount to the frame.

>=20
> I put similar brackets on my car.  They are the easiest design to fit, tak=
ing about 30 minutes to install.  I purchased my brackets from someone who m=
ade them for his car for $40.  I bought the shocks from Pep Boys for $12.95 e=
ach.  The VB shocks must be pretty good to command the $189 price tag.  My d=
riving can often be aggressive, especially at autocross events (2nd place in=
 class at the Moss festival and first overall at Triumphest in 1998).  The c=
heap shock seem to work fine for me in the rear, though I may just not know a=
ny better.  The PO put Koni's on the front.
>=20
> Installation made a tremendous improvement in my car, but that's because m=
y lever shocks were dead.  I've heard lots of good things about the heavy du=
ty rebuilds to the lever shocks.  Doing it again, I'd give this serious thou=
ght.
>=20
> Disadvantages of this design:
> - When the car is in the air, the limit stop for the trailing arm travel i=
s the tube shock.  I had a shock fail after only a year (exchanged for free r=
eplacement).  I think the other one may also need replacement, as there's oi=
l on the tube.  This tension is transferred through the shock to the bracket=
, at a slight angle, torquing the frame cross member that holds the shocks a=
nd rear differential mounts.  I mention this because I just discovered sever=
al broken welds including both rear differential mounts and the crossemember=
 to frame connection near the right shock mount.  The car had the differenti=
al reinforcing brackets installed for the DPO.  I don't know if the shock co=
nversion caused this, but I think it aggravated the problem.  (Any comments o=
n this from others?)
>=20
> - You are limited in tire width to 205 series tires, which may rub the bra=
cket if you have lots of camber or weak springs.
>=20
> Safety considerations:
> - The Gabrial shocks I purchased only have a single nut on each end of the=
 shock. The guy I got the brackets through had a shock come undone.  Your sh=
ocks should be double nutted.  I used a nylocs because I had a box of them, b=
ut any nut should work.
>=20
> - Check the tires and brackets for rubbing.  I have a little bit on the ri=
ght side recently, but nothing I'm concerned about.  I can't see any indicat=
ion on the tire, just some rubber dust on the bracket.  I run 205/65 tires a=
nd will adjust the camber on the right tire.
>=20
> If your into welding, you can make your own brackets looking at the pictur=
e.  Drop me an e-mail and I'll look up the shock number again.  It's off 50'=
s Studebakers and Cadillacs if I remember correctly.
>=20
> The Moss kit is an effort to install.  It has three triangular brackets pe=
r side.  One to the standard shock mount, the second inside the body by the f=
uel tank, and the third in the wheel well area.  The first step in the instr=
uctions was to remove the fuel tank.
>=20
> I'd always avoid a shock that only bolts to the body.  The dampening force=
s need to go to the frame.

That happened to my TR4A IRS twice and both times the passenger side shock a=
bsorber mounting bolts backed out. Red Locktite solved the problem.

p><p class=3D"MsoNormal">Will - I'm not as familiar with the solid axle of t=
he TR4, so this may or may not be relevant to your situation.&nbsp; <br><br>=
There are at least three styles of tube shock conversions for the TR6 and I a=
ssume the 4A.&nbsp; The one with three triangular brackets that go through t=
he body (likely the one you looked at from Moss), A bracket that bolts to th=
e body with no frame attachment, and a single plate bracket that bolts to th=
e lever shock mount.<br><br>Also watch for feedback on people that just get t=
he lever shocks rebuilt with a heavy duty rebuild.&nbsp; If I was starting o=
ver, that is probably what I would do.<br><br>A sample of the three plate de=
sign at Moss is 670-128 - see <a href=3D"https://mossmotors.com/rear-tube-sh=
ock-conversion-kits">https://mossmotors.com/rear-tube-shock-conversion-kits<=
/a> - the Monroe shock version for the 4A is available.&nbsp; They have an a=
rticle at <a href=3D"http://www.mossmotoring.com/tr6-tube-shock-conversion/"=
>http://www.mossmotoring.com/tr6-tube-shock-conversion/</a>&nbsp; It looks l=
ike a sturdy design, but takes significant effort to install.&nbsp; Read the=
 instructions from their website.<br><br>I do not recommend the bracket that=
 just bolts to the body without a frame attachments.<br><br>I used the singl=
e plate version because it was much easier, but this design leads to flexing=
 of the frame cross member and cracking of the frame, including mine.&nbsp; S=
ee the 0091, 2217, and 2218 images attached of other people's cars discovere=
d at a local club tech clinic.&nbsp; If you have this design, I recommend yo=
u check the frame cross member regularly.&nbsp; If you have the rear spring o=
ut for any reason, run the trailing arm through its full range of motion and=
 you will probably see the top of the shock mount move front to rear.<br><br=
>After having my frame cracks welded, I built a new version of the single pl=
ate design available from some vendors.&nbsp; I extended the top mount for t=
he shock back about two inches and added two braces.&nbsp; One is a length o=
f 1" angle iron that goes between the two shock mounts near the top of the b=
racket, just below the body to side to side stability.&nbsp; The other is th=
e more important addition and goes from the top of the shock bracket rearwar=
d to the frame at about a 45 deg angle.&nbsp; This one stops any front to re=
ar motion of the shock bracket.&nbsp; Unfortunately the car isn't easily acc=
essible right now and I can't find my pictures.<br><br>Below is an item I wr=
ote 20 years ago or so.&nbsp; The 5-6025 kit is the single plate design that=
 in my opinion needs at least the added bracket from the top of the shock mo=
unt to the frame.<br><br><br><o:p></o:p></p><h2 align=3D"center" style=3D"te=
