EFS Shock Absorber Bush, Polyurethane Upper and Lower 19 x 55 x 14 mm
EFS polyurethane stem bush, 19 x 55 x 14 mm in 80 Duro elastomer. Serves as the upper bush on the 36-5545, 37-6001, 37-6006, 39-7001 and 39-7004 shocks and as the lower bush on the 37-6002, 37-6006 and 39-7001.
EFS Shock Absorber Bush, Polyurethane Upper and Lower 19 x 55 x 14 mm
The lower-profile member of the same bush family: 19 mm of length instead of 23/19 mm, on the same 55 mm diameter and 14 mm bore.
The 80 Duro polyurethane does exactly what tired rubber cannot — it holds its dimensions, does not spread on the stem, and damps vibration instead of passing it straight on.
Material 80 Duro polyurethane | Position Upper or lower | Dimensions 19 x 55 x 14 mm | Bore 14 mm |
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 EFS 36-5545, 37-6001, 37-6006, 39-7001 and 39-7004, and as the lower stem bush for 37-6002, 37-6006 and 39-7001
What are its dimensions?
Length x diameter x bore: 19 x 55 x 14 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.
How does it differ from PB1454?
Length. PB1454F is 19 mm, PB1454 is 23/19 mm. The 55 mm diameter, the 14 mm bore and the shock absorber list are identical.
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.
