EFS Leaf Spring Slide Pad, PTFE, Round 39 mm
A round PTFE slide pad from EFS, fitted between the leaves of a leaf spring pack. 39 mm across, 10 mm tall, with a 12.5 mm locating boss. It cuts friction and noise in the pack and slows down wear on the leaf surfaces.
EFS Leaf Spring Slide Pad, PTFE, Round 39 mm
A pack that creaks over every driveway and a rear end that moves in steps rather than smoothly is usually not the fault of the leaves themselves — it is the friction between them. Steel on steel damps nothing and quietly grinds the surfaces away.
This round PTFE pad from EFS sits between the leaves and separates them with a very low-friction polymer. It costs almost nothing and noticeably changes how the pack works.
Material PTFE | Shape Round | Diameter 39 mm | Height 10 mm |
Key benefits
- PTFE has a very low friction coefficient, so the leaves slide instead of grinding against each other.
- A quieter pack: less creaking and knocking as the suspension works over rough ground.
- Less friction means slower wear on the leaf surfaces and a longer life for the whole pack.
- Smoother leaf movement makes the truck more predictable when loaded.
- Fits EFS leaf packs across lift heights (30-50 mm, +2") and load ratings.

This is for a leaf-sprung 4x4 whose rear works hard: constant load, a canopy, or regular time off the bitumen. EFS states the pads suit its own packs made from Japanese SUP9/SUP9A steel, with tapered leaf ends and clamps that stop the pack from splaying.
Fitting notes
The pads sit between the leaves, where the leaves rub against each other. They are a service item, best replaced while the pack is apart rather than as a standalone job. If you are rebuilding a pack or fitting a new EFS set, order enough pads to cover every contact point in one go.
Why it is worth it
- The cheapest way to make a leaf pack quieter and smoother.
- Stated dimensions instead of a generic pad in an unknown plastic.
- A natural addition to an EFS leaf set when the pack is being built up.
If the pack is coming apart anyway, add a set of pads to the order — you will not want to pull it down twice.
Frequently Asked Questions
Where exactly does this pad go?
Between the leaves of the pack, at the contact points — the 12.5 mm boss locates it in the hole.
What are its dimensions?
39 mm outside diameter, 10 mm overall height, 6.5 mm boss height, 12.5 mm boss diameter.
What is it made of?
PTFE, commonly known as Teflon — a very low-friction, wear-resistant polymer.
Which leaf packs does it suit?
The distributor lists compatibility with EFS packs in SUP9/SUP9A steel, across 30-50 mm (+2") lifts and load ratings.
How is it different from the rectangular version?
Shape and location. P90052 is round with a round boss; P90074 is a 43.3 x 33.5 mm rectangular pad with an oval locating boss.
