EFS shock absorber bush, 80 Duro polyurethane — 38 x 38/33 x 22 mm
EFS polyurethane shock absorber bush made from 80 Duro elastomer, measuring 38 x 38/33 x 22 mm. It fits into the shock eye as the damping element: it keeps play out of the mount, quietens vibration and resists oil, abrasion and weather. Designed for EFS 4x4 shock absorbers.
EFS polyurethane shock absorber bush, 80 Duro — 38 x 38/33 x 22 mm
A shock absorber only does its job when it sits firmly in its mount. Let the bush in the eye flatten out and every decent bump turns into a knock, while a carefully specified suspension starts working imprecisely.
This bush is made from 80 Duro polyurethane — an elastomer that deforms less under load than rubber and takes far longer to lose its shape. It fits into the shock absorber eye as the damping element: it carries the load, kills vibration and keeps play out of the mount.

Key benefits
- 80 Duro polyurethane instead of rubber — less play in the mount and better vibration damping, so the vehicle settles down on corrugations and bumps.
- Resistant to oil, abrasion and weather — this bush lives in the dirtiest place under the car and does not give up at the first oil splash.
- Resistant to permanent deformation — the mount holds its dimensions longer, so you come back to the same job less often.
- Tight fit on the pin — less play means less noise and less wear on the shock absorber itself.
- Designed for EFS 4x4 shock absorbers, built for hard off-road use.
Specifications

This is a part for drivers who use the terrain regularly rather than occasionally — that is where bushes wear fastest. Replace them when fitting new EFS shocks, at a post-season suspension check, or when that familiar knock starts coming from the shock mount.
Fitting and notes
The bush goes into the shock absorber eye. Check your mount dimensions before ordering — the 22 mm bore and 38 mm length are the numbers that matter. Shock mounts normally take bushes in pairs, so count the pieces for a full set. If you are unsure, send us your shock absorber part number and we will verify the fit in the workshop before dispatch.
Why buy this
- A small, cheap part that decides whether your suspension stays quiet and tight.
- 80 Duro polyurethane holds its shape longer than rubber — fewer repeat visits for the same fault.
- Made for EFS shock absorbers, not a generic substitute chosen by eye.

Frequently Asked Questions
What exactly are the dimensions?
38 x 38/33 x 22 mm — 38 mm length, 38/33 mm diameter and a 22 mm inner bore.
Why polyurethane rather than rubber here?
The manufacturer states that 80 Duro polyurethane gives less play, better vibration damping and longer shock absorber service life, and that it resists deformation, oils, abrasion and weather.
Where does this bush fit?
Into the shock absorber eye, as the damping bush that reduces vibration and noise.
Which shock absorbers is it made for?
The manufacturer specifies EFS 4x4 shock absorbers. No individual shock part numbers are listed on this product card, so the safest check is against your mount dimensions — or send us your shock absorber number.
How many pieces do I need?
Shock bushes normally work in pairs per mount. Confirm the exact count when you remove the old ones.
