EFS Shock Absorber Bush, 80 Duro Polyurethane, 38 x 37/32 x 16 mm
EFS polyurethane shock absorber bush in 80 Duro elastomer, 38 x 37/32 x 16 mm. Fitted into the shock eye, it damps the vibration and noise the suspension sends into the body. Against rubber it gives less play, handles oil and moisture better and keeps its shape far longer.
EFS Shock Absorber Bush, 80 Duro Polyurethane, 38 x 37/32 x 16 mm
Off-road suspension rarely dies all at once — first it starts to knock. That knock almost always comes from the bushes in the shock eyes, because they absorb every jolt and every dose of muddy water thrown at them.
EFS specifies 80 Duro polyurethane for its damper bushes instead of plain rubber. You do not feel the difference on day one — you feel it after a season. Rubber in a shock eye works itself loose under oil and heat; polyurethane keeps its dimensions and does not hand the damper play it never asked for.
Material 80 Duro polyurethane | Dimensions 38 x 37/32 x 16 mm | Bore 16 mm |
Key benefits
- 80 Duro polyurethane holds its dimensions far longer than rubber, so the shock eye does not start to wander after a few trips off road.
- Less play between bush and pin means the damper works more precisely and the vehicle stays predictable.
- Resistant to oil, grit, moisture and UV — it will not go soft from grease or crack in the sun.
- Damps the vibration and noise the suspension would otherwise send into the body.

Who it is for
For drivers running EFS suspension who regularly leave the tarmac — expeditions, forest tracks, work in the field. Polyurethane proves itself exactly where rubber gives up early: in mud, water and around grease.
Fitting notes
The bush presses into the shock eye. Check the housing length before ordering — the same 16 mm EB2 range also has a shorter 35 mm version, and the two are easy to confuse. Note which side and which end you are working on so you order the right quantity.
Why it is worth it
- 80 Duro polyurethane instead of rubber — less play and a longer working life for the damper.
- Confirmed dimensions of 38 x 37/32 x 16 mm, so selection is unambiguous.
- A catalogue part from the suspension maker, designed for EFS 4x4 dampers.
Stripping the suspension anyway? Change the bushes while you are in there — it is the cheapest line on the list and you hear the difference on the first drive.
Frequently Asked Questions
What are the exact dimensions?
38 x 37/32 x 16 mm — length x diameter x bore. The bore is 16 mm.
Why polyurethane rather than rubber here?
80 Duro polyurethane keeps its rebound properties longer than rubber, controls play between bush and pin more tightly and resists oil, grit, moisture and UV. The result is less noise and vibration and a longer working life for the damper.
How does it differ from EB2X16PX35?
Length: EB2X16PX38 is 38 mm and EB2X16PX35 is 35 mm. Both are EB2 type with a 16 mm bore.
Which dampers is it intended for?
The manufacturer's page describes it as dedicated to EFS 4x4 dampers without listing individual part numbers, so the safest way to select it is by measuring the housing.
