Hydraulic cylinders do the physical work: lift cylinders raise the mast, tilt cylinders angle it, and side-shift cylinders move the carriage. ForkliftIQ supplies complete cylinders and seal kits compatible with Heli, Hangcha, EP, Toyota, Linde, Jungheinrich, Hyster, Crown and other major brands.
Cylinder leaks and reseal
Oil on the mast or a slowly settling load usually means worn rod or piston seals. A reseal kit is often enough; bent rods or scored bores need a new cylinder. Send a photo of the leak and the cylinder number for the right kit.
Parts grade — OEM, aftermarket & economy
| Grade | What it is | Best for |
|---|---|---|
| OEM / Genuine | Original manufacturer part number | Warranty & critical components |
| Branded Aftermarket | Reputable replacement brands (Curtis, EVE, etc.) | Best value + reliability |
| Economy / OE-equivalent | Cost-optimized equivalent | Budget & wear items |
Grades are indicative; we confirm the exact match against your part number or nameplate photo.

To match the correct part the first time, have these details ready (or send a photo and we cross-reference):
- Function — lift, tilt or side-shift
- Bore and rod diameter, stroke length
- Mounting type (eye, clevis, trunnion)
- Seal kit only vs complete cylinder
- Brand, model and cylinder number

Frequently Asked Questions
Why is my forklift mast leaking down?
Worn lift-cylinder seals (or a control-valve spool) let the load settle. A seal kit usually fixes the cylinder.
Do you sell seal kits or whole cylinders?
Both — reseal kits and complete lift, tilt and side-shift cylinders.
How do I order the right seal kit?
Send the cylinder bore/rod size or the cylinder part number and a photo.
Can a bent rod be resealed?
No — a bent or scored rod needs a new cylinder; seals alone won’t hold.
Need this part fast?
Send the brand, part number or a nameplate photo — we cross-reference and quote from a worldwide parts network.
