EFS Shock Absorber Bush, Polyurethane Upper Front for 36-5552 — Toyota Land Cruiser 100, Lexus 470
Upper polyurethane stem bush for the EFS 36-5552 front shock absorber. 24/21 x 51 x 16 mm in 80 Duro elastomer. Covers the Toyota Land Cruiser 100 and Lexus 470 application from 2000 onwards.
EFS Shock Absorber Bush, Polyurethane Upper Front for 36-5552 — Toyota Land Cruiser 100, Lexus 470
On a well-travelled 100 Series the upper front shock bush rarely survives a second set of dampers. The symptoms are always the same: a dull knock as you creep over a kerb and a front end that seems to respond late.
This EFS bush is part of the upper mount for the 36-5552 front shock absorber. 80 Duro polyurethane instead of rubber means less play on the stem and a much longer run before the knocking returns.
Material 80 Duro polyurethane | Position Upper, front | Dimensions 24/21 x 51 x 16 mm | Shock EFS 36-5552 |
Key benefits
- 80 Duro polyurethane holds its shape far longer than rubber, so the play does not come back after one season.
- Less play between the bush and the shock stem means more precise damper action and fewer knocks over bumps.
- The material shrugs off oil, grit, moisture and UV — everything a shock mount actually lives in.
- Better vibration damping means a quieter suspension and less noise carried into the body.
- Made for EFS 4x4 shock absorbers and aimed at hard off-road use.

This is for anyone servicing an EFS suspension who wants the shock mount to be as fresh as the damper itself. Polyurethane instead of rubber pays off on a vehicle that regularly sees rough ground, carries load, or is simply meant to cover a lot of kilometres before the play comes back.
Fitting notes
The bush works on the shock absorber mounting stem, between the eye and the body or bracket. It is replaced with the shock off the car, together with the washers from that side. If you are fitting new shocks, change the bushes at the same time — a tired bush will spoil the feel of a brand new damper. Check how many pieces one mount takes on your vehicle before ordering.
Why it is worth it
- Published dimensions and a shock list, so you match the bush by part number rather than by eye.
- 80 Duro polyurethane: less play and a longer life than the rubber equivalent.
- A small part that decides whether a new shock absorber actually performs as it should.
Ordering shocks? Add the bushes to the same order — doing both while the suspension is apart saves an hour of labour.
Frequently Asked Questions
Which shock absorbers does this bush fit?
as the upper stem bush for the EFS 36-5552 front shock absorber
What are its dimensions?
Length x diameter x bore: 24/21 x 51 x 16 mm.
Why polyurethane rather than rubber?
80 Duro polyurethane keeps its rebound properties longer, leaves less play on the stem and damps vibration better. It also resists oil, grit, moisture and UV.
Which vehicles is the 36-5552 shock listed for?
The distributor lists the Toyota Land Cruiser 100 (2000+) and the Lexus 470 (2000+).
When should the bushes be replaced?
Ideally when the shocks are replaced, or as soon as you hear knocking and feel play around the mount. A worn bush spoils the action of even a brand new damper.
