Tough in the Rough

Arguably the oldest (and best) replacement steering bar for Land Rover vehicles (and also Toyota 80s to order).

Manufactured by Gwyn Lewis 4×4 in Wales, U.K.

 

Will accept standard LR track rod ends (RTC5869 + RTC5870).  We can supply HD greasable versions of these.

 

SUMOBARS are the original Heavy Duty Steering Bars and arguably still the best, they are used all around the world from on road, off road, comp safari to extreme off road.

 

There are 4 types of steering bars:

SUMO-HD—-These are made from 30mm solid EN8 engineering grade CARBON STEEL BAR, designed to be used by all, on & off road.

SUMO-HDH—-These are made from 29mm hollow 7mm wall CDS engineering grade CARBON STEEL TUBE, designed to be used by ALRC competitors who must comply with hollow steering bar regulations & those wanting a strong steering bar without having that extra weight of a solid bar.

SUMO-EXT—-These are made from 32mm solid EN8 engineering grade CARBON STEEL BAR, designed to be used by off road competitors, these are very heavy duty.

SUMO-SS—-These are made from 30mm solid 303 STAINLESS STEEL BAR, these bars are very strong, the stainless offers a much greater strength as it is 1.5 times stronger than steel, these bars can be used from on road to extreme off road use, they are also supplied with stainless steel locking nuts.

 

Notes:

1.  Not all applications are available in all four versions.

2.  RoverWare.US usually stock all varieties of Sumo HDH, with other varieties to order.

3.  RoverWare.US also try to stock Sumo HD and Sumo SS for Discover 1 / Range Rover Classic / Defender, drag links only.

We believe that if you need the strength of the "HD" or "EXT" (extreme) or "SS" version for the tie bar (/rod) then you are better to fit a track rod guard (that we also carry).  The loading caused by hitting a rock or resting the entire vehicle on the drag link is likely to damage the ball joints, steering arms, or other steering components and you clearly need more protection!

 

All the Sumobars are supplied with locking nuts.  The Sumobar lock nuts are full nuts (not like the cheaper copies which come with half nuts),  this is for strength and security with less chance of rounding the nut whilst tightening them.  Both ends of the Sumobars have machined flats for ease of tightening the lock nuts to the bar, and the right hand thread is easily identified with a grove machined around the bar and the lock nut.

Please remember all SUMOBARS are British made from engineering grade steel, not to be confused with cheaper copy bars made from a low grade of mild steel.
