Strut Inserts (shock absorbers) for the front suspension: Datsun 1200 (B110) uses 45 mm diameter strut tubes. Most other Datsuns, including B210, use a larger 2.0 inch (50.8 mm) size. This article will help you choose parts for rebuild or replacement.

Overview

The 1200 front shock absorbers can be rebuilt. Or you can fit strut insert cartridges, such as NOS KYB gas-a-just or the commonly available VW inserts.

Shock Absorber Cartridges for Datsun 1200 struts

Direct Interchange

Datsun 1200s did not come with strut insert cartridges, instead the struts contained had rebuildable shock absorbers (wet shocks). Later, Nissan offered strut inserts specifically for the 1200, which are still available in USA as of May 2008.

Using a factory-quality Strut rebuild kit (rather than removing the factory strut parts and replacing with a new strut 'cartridge' insert) is the way to retain a smooth front-end ride. However, these kits are no longer manufactured. Using the genuined Nissan cartridge (same as early A12-powered B210s) is just as good.

1981 Pulsar inserts are the same external size as Datsun 1200 but shorter by 82 mm (3-1/4 in) so if you are after lowering with out banging on the spring mounts this is a easy way to go only 10mm (3/8) shorter in the stroke.

VW Golf/Rabbit

Get Bilstein (1.507 in) or KYB brand at about 1.5 inch outside diameter. Tokico and KONI are too big around to fit 45mm strut housings.

Bilstein shock inserts

Golf Mk I insert is nearly 4 inches shorter than stock and will need a simple spacer made to make up the difference in length in the bottom of the tube.

Strut piston diameter is larger than B110, so drill out the strut-nut and the strut top hole.
