Series Land rover Chassis?

But as has also been said, in a Land Rover chassis flex is also (almost) irrelevant as there isn't a lot of flex in a Land Rover chassis. That said a 110/Defender chassis flexes a lot more than a 109" chassis mainly because of the loss of at least 3 cross members and the reduction in size of another in the 110 chassis.

I am yet to see a proper definition for "really heavy" in this thread.

My definition is steep hills/washouts/holes/rocks/etc....
I know there aren't many serious hills in WA, so your definition may be different?

I have been on hills where a SWB landie has flipped over backwards, yet a 109 or 110 (even a 130) can climb it safely.

Actual chassis flexibility does not enter into it either with Landrovers or any other modern four wheel drive, although the Landrover chassis really is less flexible than some others (e.g. Landcruiser), even in these more flexible chassis the amount of axle articulation that is gained is negligible compared to the axle movement allowed by the springs.

The reason I ask Is because my Suzuki LJ ute has a stiffer chassis than the SWB LJ due to more crossmember's and bracing along the bottom middle of the chassis..


So What is the secret to the good wheel travel of the series 1, spring spacing, shackle design:confused:

So the 80 inch would have more wheel travel than the 107 inch due to shorter wheel base:confused:

SWB have more rear wheel travel because the springs are mounted differently.

The SWB has the spring mounted directly under the chassis rails, whereas the LWB has the spring mounted outside the chassis rails. So with the same amount of spring flex the wheel travels further. (I tried to find pics but google wasn't cooperating tonight)

that's the best I can do atm.... Short then long respectively

Thanks mate..I wounder why the changed the location of the springs?:confused:

Just how capable are series 1 SWB's off road???..Compared to say a CJ jeep, FJ40 ect

Never driven one myself!

The springs at the rear of the long wheelbase were moved out to reduce body roll, as the longer wheelbases were found to be carrying higher loads more often. The improves wheel travel on Series Landrovers compared to some competitors is largely a matter of using long, relatively soft springs, and having a lot of shock absorber length. Setting the springs closer to the centre on the swb also helps, and short wheelbase and relatively narrow track helps in the sense that with all the wheels close together, the whole vehicle can follow the irregularities, although as pointed out above wide track and long wheelbase also have advantages. It all depends on the circumstances.

As to the offroad capabilities of the Series 1 compared to the various comparable models - it depends a lot on which offroad and which model you are comparing it to. All short wheelbase Series 1 are less powerful than the FJ40 or the Jeep CJ, but are also lighter, and, compared to the FJ40 (I don't know enough about the Jeep) have lower centre of gravity, lower low range, and four instead of three speed gearbox. How these play out depends on the terrain.

Body roll, the wider the springs are apart the less the upper body rolls around on the springs.

The 88" Land Rovers were superior to the original 3 speed FJ and comparable to the4 speed FJ40, but both marques had benefits and deficiencies.

There are a lot more Land Rover 88" still running around the place than there are FJ40 because the bodies haven't rusted away as much.

My brother used to have a business replacing the broken rivets on suspension brackets of the F40 series models, particularly the long wheelbase models until the 70 series with welded chassis came along.

So which is better?
