Raptor fishtail over small bumps

So I took it to the country side and over small bumps it was okay. But larger bumps and around 25mph it fishtail again. Just a bit better than before. If it’s how the raptor is, I’m a bit scared to drive and suddenly hit bumps at high speed.

When you say small bumps are you talking about washboards where there are a lot of bumps in a row or are you talking about hitting a single small bump and the rear getting upset?

A lot of bumps in a row my friend. One single bump is okay because I lowered the rear tire pressure.

Washboards will usually upset the rear of a live axle vehicle, that's normal. Putting flutter stacks in the shocks when rebuild time comes can help. Its sort of inevitable, the little bumps are coming faster than the suspension can cycle so the tires are either fully off the ground or have very little contact pressure in between the washboards. That means any left or right loading IE road crown, wheel speed differential, vehicle imbalance, whatever is going to make the truck sway a little. You can either speed up or slow down to try and make the suspension handle it better. Most people run even lower tire pressure on this sort of terrain.

Or just hammer it and enjoy the drift!

Can you post some pictures of the roads? Always enjoyed other parts of the world.

I took this photo before going through those bumps.

Nice shot! What cold pressure are you running? Have you tried the same run in 4A?

I leave it in 4A all the time. It's feel smoother when power is delivered to front and rear.

I have noticed less rear end hopping with 37s, probably due to the increased mass.

You mean it's less hopping in the 37s psi? I felt the opposite. If I put more pressure to the rear it will hop more.
