Speed Upgrade for Mercedes 4x4 Truck

Posted on Thursday, 10 January, 2019 by Paul

Peter contacted us from the snowy depths of British Columbia, Canada about his splendid 4x4 Mercedes 1617 truck camper.

The truck was a pleasure to drive but max cruising speed was 80kph (50mph).

That is fine in the snow but Peter assures us it doesn't snow all year round and Canada is huge so Peter was keen to increase the cruising speed of the truck.

The complications is that the rear axle has hub reduction units and the front doesn't.

We dusted off the technical data booklets and researched ratios available for front & rear crown wheels & pinions and after some careful calculations we were able to provide Peter with axle gearing which gives an impressive 30% gain in speed.

Canada remains huge but peter can get about a good deal more efficiently now!

Peter has said -

The new gears provided me with a nice 98-100km/hr highway speed at 22-2300 rpm.

On this truck we were able to use original parts but we do now have a trusted supplier who can create bespoke faster ratio crown wheel & pinion sets to suit any truck.

We are now preparing the parts to give a speed upgrade to two more Mercedes four wheel drive trucks.

When I bought my U1000 “Rustbucket” , Simon gave me a fair & frank appraisal of its condition. The mog was cleaned and shipped professionally with no issues upon landing here in Australia. Since then, AV has provided me with excellent spares support and the occasional bit of advice. Posting was always prompt and economical via Royal Mail – this has taken a lot of the pain out of restoration. Highly recommended.

Atkinson Vos not only supplied my Unimog some years ago but they have been ever present when I needed any advice or assistance. My Unimog recently underwent a full refurbishment in their workshop and I have to say the result has been nothing short of superb. My Moggy is not only in great mechanical shape but it looks great too. Top marks Atkinson Vos.

Anything is possible, and everything is done to a very high standard!. Atkinson Vos prepared my Unimog to an excellent standard. Their aftersales service is great too.

We have been using Atkinson Vos for a number of years now, they have carried out some upgrades and all servicing and repairs, their staff are friendly and always willing to help. The workshop guys always offer advice and easy fix solutions over the phone and on the odd occasion visited our workshop to view and inspect the vehicle. I would not hesitate to recommend the company, Thanks to all the staff.
