SUMOBARS

“Tough in the Rough”

Arguably the oldest, (and best) replacement steering bars for Land Rover vehicles.

Manufactured by Gwyn Lewis 4×4

Will accept standard LR track rod ends (RTC5869 + RTC5870) we 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.
We now manufacture 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 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.


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.
