shocks

Do the boge 911 72-76 fits on the 914 ?

Do you mean shocks or struts? AFAIK, the inserts will go into the 914 struts.

This is one of those things that I've never fully understood. What's the difference between shocks and struts? What's involved with switching out shocks vs switching out struts? Are there advantages or disadvantages of one or the other? hopefully I'll finally understand. Thanks.

Shock and strut seemed to be used interchangeably. I think technically the usage is incorrect. On the front of the 914 we have a strut which is composed of a strut housing and a strut insert. On the rear we have a shock.

Thanks for your answers

tell me both:

if are boge struts inserts or only covers do will fit ?

{let's see how much of this I can get right from memory}

both shocks and struts are designed to control the up and down action of the car as it hits bumps, dips in the road, etc. They usually offer little resistance on compression but significant resistance on extension.

a typical traditional suspension consists of upper and lower control arms hooked to a wheel hub via ball joints top and bottom (steerable if in the front). the support for the weight of the car is provided by a spring or torsion bar acting on one of the control arms. a shock absorber is used to control the rebound of the spring once it is compressed by an upward force (like a bump in the road). The shock is mounted between the frame and one of the control arms. The control arms are what determine the arc that the wheel hub swings from full jounce to full rebound.

"Struts" are the common reference to a MacPherson strut, a design that integrates the traditional function of the shock absorber with a tube that serves in place of the upper control arm in a traditional suspension. I think (not positive) that all MacPhersons also use a "coil-over" arrangement where the coil spring that supports the weight of the car fits over the outside of the strut tube. The strut is an integral component in determining the arc the wheel hub; if you removed it the hub would just flop over to the side and hang from the lower control arm.

When changing/replacing struts, you can either change the whole assembly, or quite often can disassemble the top end of the strut tube and just replace the 'strut insert'. This is the shock absorbing portion of the assembly.

the rear of the 914 has a "coil-over" shock assembly on a trailing arm suspension, which is a traditional shock with a coil spring mounted over the outside of it. However, even if you take the shock/spring off, you will see that the balance of the rear suspension remains effective and determines the arc that the wheel will swing.

Thanks for your answer.

But, Do are the same shocks and struts in 72-74 911 than the 914 ?

A listing I found shows the same front strut inserts for a 1972 911E as for a 1972 914/4. The rear shocks are not the same.

You can send them to me and I'll let you know if they fit!

P.S. I see from your web page you go to Queretaro. I was there in June and it's a beautiful city, especially the town squares in the city center. They must have about 10,000 Nissan taxicabs!

Any 69-89 911 strut can be installed on a 914. You will have to deal with brakes, ball-joints (early vs late) and wheel-lug pattern though.

Of course that is the whole reason most people do it (i.e. 5-lug conversion with bigger vented brakes).

Will 98D:

HI,

Yes, is beatiful city, is one if a few places in México where tha cabs are nissan becaue in any other city the cabs are bugs.

campbellcj:

Please explain this:

Bilstein front shocks ?

regards

Maybe I am confused - is the question about the entire strut assembly or the strut cartridge (insert)?

Your other post was about Bilstein vs. Boge types of inserts, which are not compatible. It is confusing because Bilstein makes inserts for Boge struts, but those inserts are different from the Bilstein inserts for Bilstein struts.

If you take a whole Bilstein or Boge (or Koni) strut+insert off a 911, it will bolt up to a 914. The ball joints were different before 73 and after 73 but the actual struts are compatible.
