NOMADTECH Hydraulic Suspension Bump Stop, 4" Travel

With a big lift and long shocks the suspension has so much travel that a factory stop stops being a safeguard and becomes an anvil – especially on a landing or a fast drop into a rut.

A hydraulic bump stop behaves differently from rubber. Instead of throwing the impact back into the body, it forces oil through internal passages and turns the energy of the hit into heat – the suspension comes to a soft stop rather than against a rigid ledge.

This is the longest variant in the family: 4 inches, or 10.16 cm of travel. That is enough distance to slow the mass of the vehicle progressively instead of stopping it dead in the last centimetre.

Key benefits

• 4" (10.16 cm) of working travel – that is the distance the oil has to arrest the mass of the vehicle; a longer stroke means a gentler stop and lower peak loads on the mounts.
• Hydraulic rather than elastic action – rubber gives the stored energy straight back and kicks the wheel up; a hydraulic stop dissipates it as heat, so the vehicle keeps contact with the ground more easily.
• Protects the rest of the suspension – it limits the shock reaching the arms, bushings and shock mounting points at full compression.
• Threaded body with locking rings – lets you set and lock the height of the stop in its mount instead of accepting a fixed position.
• Contact cap on the shaft – spreads the load over the surface the stop strikes rather than point-loading the arm.

Technical data

• Type: hydraulic suspension bump stop (BUMPSTOP)
• Travel: 4" (10.16 cm)
• Manufacturer: NOMADTECH
• Purpose: prevents harsh suspension bottom-out

Who it is for. For competition suspensions and heavily lifted vehicles with long shocks, where the working range is large and the energy at bottom-out is correspondingly higher. Twice the travel of the 2" version means twice the distance the stop has to work in before the suspension goes solid.

Fitting notes

A hydraulic stop needs its own strike point – usually a tube or cup welded to the frame or axle, lined up precisely with the path of the arm. The distributor listing gives no installed dimensions, no thread specification and no vehicle list, so choosing the location and building the mount is workshop work. If you are building a suspension from scratch, get in touch – Szekla4x4 also runs a workshop that does exactly this kind of fabrication.

Before the first drive, cycle the full range of travel with the vehicle up on stands: the stop has to engage before the shock reaches the end of its stroke, and the shaft must not work at an angle.

Why it is worth it

• It turns a hard bottom-out into controlled damping – a difference you feel in the cabin and see in how long the suspension lasts.
• 4" of travel is a concrete, checkable selection figure, not a vague promise of "more comfort".
• Part of a family with three stroke lengths, so you can match it to the space your build actually has.

If your suspension regularly reaches the end of its travel, this part goes to work at precisely the moment the rest of the system takes the biggest hit.

Frequently Asked Questions

How much travel does this stop have?

4 inches, which is 10.16 cm.

How does a hydraulic bump stop differ from a rubber one?

Rubber is a spring element – it stores the impact energy and gives it straight back. A hydraulic stop forces oil through internal passages and converts that energy into heat, so the suspension stops more gently and does not throw the wheel back up.

Will it fit my vehicle?

The distributor listing gives no vehicle list and no installed dimensions – this is a universal part for suspension builds and requires a purpose-made strike point. It is worth discussing the choice with a workshop that knows your suspension setup.

How many do I need?

One stop works on one wheel, so an axle needs two. The listing describes a single unit – choose the quantity to match the number of points you want to protect.
