EFS Shock Absorber Bush, Polyurethane Upper for 36-5586 — Toyota Land Cruiser Prado 120 & Fortuner
Upper polyurethane stem bush for the EFS 36-5586 shock absorber. 21/18 x 39 x 12 mm in 80 Duro elastomer. Covers the Toyota Land Cruiser Prado 120 (2003-2009) and Toyota Fortuner (2004-2015+) application.
EFS Shock Absorber Bush, Polyurethane Upper for 36-5586 — Toyota Land Cruiser Prado 120 & Fortuner
A fresh shock in a Prado can still disappoint if it sits on a tired rubber bush. Play on the stem means a knock over every kerb edge and part of the travel absorbed by the mount instead of the damper.
This polyurethane EFS bush is the upper mounting element for the 36-5586 shock absorber. The 80 Duro elastomer holds its dimensions far longer than rubber and moves much less under load.
Material 80 Duro polyurethane | Position Upper, stem type | Dimensions 21/18 x 39 x 12 mm | Shock EFS 36-5586 |
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 36-5586 shock absorber
What are its dimensions?
Length x diameter x bore: 21/18 x 39 x 12 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 36-5586 shock listed for?
The distributor lists the Toyota Land Cruiser Prado 120 (2003-2009) and the Toyota Fortuner (2004-2015+).
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.
