Datsun 1200 used tradional shock absorbers in the rear suspension (the front used a McPherson strut). Shocks differ between coupe, sedan and wagon (van). Kayaba (KYB) and Tokico are the factory rear shock brands, so they are good. These came in a black tube. Oil shocks are recommended for street use.

Shock Interchange Tips
As 1200 shocks are no longer in stock, choosing an alternative shock has become the norm.
- For cars that have been lowered, see #Lowering Shocks section below
- Ensure the shock does not bottom out. For Coupe, wagon and ute, the weight of the car must not rest on the shock (it should instead bottom out on the bump stops). Too long of shock, and at full bounce, the shock will bottom out leading to early wear. When fitting, push down on the rear side and ensure the spring hits the bump stop. If it stops before hitting the bump stop, the shock is too long (compressed length is not short enough)
- Ensure the shock has enough rebound length (extension). Loosen the lower shock mount, then Jack the car up one side, letting the wheel hang down. See if the shock will still slip into the mount. If the shock extended length is too short, it won't fit, and it will cause the suspension to stop short when going over holes, etc.
- Coupe shocks use smaller lower mounts (8mm) than most shocks (12mm). Swap the lower bushings OR use KYB KIT105 sleeve adapter (reduces lower mount from 12mm to 8mm bolt size)
Gas Charged
Gas charged shocks became available in 1972
- They raise the car up 10-15 mm
- They can work better on bad road surfaces - for example washboard roads - as the gas pressure keeps the oil from aerating under extreme vibrations
Overview
Shocks differ for Sedan, Coupe, Van and Truck.
- Coupe shocks are similar to sedan shocks (both have upper threaded bayonet), but Coupes have smaller piston shaft.
- Sedan shocks are stronger and have a bump stop -- they can support the weight of the car under full bounce.
New aftermarket shocks can cause bounce. The genuine Nissan shocks are carefully tuned for the stock suspension and do not cause bouncing. Most all aftermarket shocks are more firmly valved and cause a harder ride. If you get adjustable units they work well.
Van (wagon) and Truck (ute) shocks are identical except for a small difference in rebound specification.
Coupe & Sedan shocks are different in physical measurements and in compression/rebound.

Aftermarket
Bilstein and KONI are considered the best mass-market shocks, while Boge, Tokico and KYB are considered quality brands. KONI classic/special is recommended for street and track.
Adjustable Shocks
Adjustable-length, adjustable-damping
See discussion: Where can you get replacement strut inserts?
KONIs are rebound damping adjustable only, so get the correct damping to start with.
KONI can rebuild most KONI shocks, so if you find a used pair or even worn out part of adjustables, call KONI to see if they can be rebuilt. The new name is "classic" or "Special-D".
KONI are twin-tube, oil filled shocks. All the control of regular gas shocks, but without the extra harsh ride that gas shocks cause.

Lowering Shocks
Sedan lowering more than 2 inches causes problems as the rear lower shock mount is on the axle housing.
Sedan
Sedan shocks have built-in bump stops. The weight of the car is designed to rest on them (they have a reinforced ledge on the shock). Also, the sedan shocks bolt to the axle housing bracket, so lowering the car compresses the shock.
You can get about 1" extra travel by cutting the Bump Stop in half (Bound Bumper A). The downside is when you hit bigger bumps it will have less cushioning effect.
Here's the other place you gotta watch. Look under your lowered sedan and see how much room between top of differential snout, and the pinion snubber. If needed, cut an inch off the snubber and reshape into cone (which helps with compression).
If your sedan shocks are actually bottoming out, measure the ones you have. Stock ones are 339 mm compressed (measured from center of eyering to shoulder of stem -- not to the end of the stem).
Coupe shocks are the go for your 2-1/2" to 3" lowered sedan -- they are 18% stiffer and 3" shorter. The issue is the small bush hole, which can be drill out to the 12 mm sedan size. Be sure to move the bump stops (bound bumpers) from your old sedan shocks to the new shocks. For sedans lowered 1" or 2" stock length shocks work fine. BUT not recommended for stock-height sedan because at maximum drop they extend 2.6" inches less.
Datsun Competition recommended modifying the shock mount by using the Coupe mount plate.
Coupe/Ute/Wagon
In general, lowering the coupe, ute or wagon does not require a shorter shock. On these models the bump stops prevent the shocks from bottoming out.
Whether lowering by reset spring, or lowering with blocks, the compressed length does not shorten. So a shorter shock is not needed.
However, removing or cutting down the bump stops will require a shorter shock. Once you cut about 1" (?) off the bump stops the standard shocks can bottom out. Coupe uses a small mounting stud, so bottoming out will either bend the stud, or the shock will be internally damaged. Ute uses a large stud, so the shock will likely be damaged before the shock stud bends. To avoid this problem, use a shorter shock — or modify the shock mounting location.
One thing that will help when trimming the bump stop is to reshape it into a cone shape (as in the original) but a shorter cone. The shape helps progressively stop the suspension compared to just cutting it off flat.
Alternatively for using longer-than-stock shocks, the lower shock mount can be moved down. See Datsun 1200 Competition Suspension Manual.
NOTE: In this photo the bump stops have been removed, allowing about 2" more compression -- although it is not recommended as it will "crash" when you go over a large enough bump. Recommendation: keep the Bump Stops but shorten them as appropriate.
COUPE: Koni 80-2359 (or 80A-2359) is reportedly for 1200 Coupe with increased suspension compression due to bump stop modification. Pedders may have a compatible shock. If you use an aftermarket shock that comes with bump stops, remove the the bump rubbers. The sheet metal of the shock was not designed to stop the weight of the car.
