Description
1 x Heavy Duty STAINLESS STEEL Steering Drag link Bar, front bar in front of axle (SUMOBARS)
Part Number :- SUMO-SS-740, Discovery 1 Drag link, Stainless Steel, Early up to 1993
Weight :- 5kg
Manufacturer :- Gwyn Lewis 4×4 SUMOBARS, these are made in the UK not cheaper imports.
Fits:- Early Discovery 1 (up to 1993) that have 1 Track Rod End Fitted. Later Discovery 1 have 2 track rod ends fitted and require a SUMO 830 bar.
These are our STAINLESS STEEL Steering Bars, (SUMO-SS) they are 30mm solid 303 Stainless Steel bar, these bars are the strongest in the sumobars range as stainless offers a much greater strength, it is 1.5 times stronger than steel, these bars can be used from on road to extreme off road use.
When fitting the SUMO LOCK NUTS onto the track rod ends use plenty of grease on the threads, this will prevent the nuts seizing onto the track rod ends, (cold welding) or (Galling) this is common with stainless steel fixings, but use plenty of grease will prevent the problem from happening, we use MORRIS K48 grease, see HERE.
The Kit includes :-
1 x SUMO-HD-740 Heavy Duty drag link bar (front bar) & 2 Full Lock Nuts left & right hand thread.
No Track Rod Ends are supplied with this one, you will need 1 x Right Hand.
Please make sure when ordering that you have 1 TRACK ROD END fitted to your original steering bar, early Disco 1 only have 1 track rod end, the later ones have 2 track rod ends fitted and require a different length front drag link bar a (SUMO 830).
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 2 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-SS—-These are made from 30mm solid 303 STAINLESS STEEL BAR, these bars are the strongest bar in the sumobars range as stainless offers a much greater strength, 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 our 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, the steel nuts are 24mm and the stainless steel nuts are 27mm, 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 made from engineering grade steel, not to be confused with cheaper copy bars made from a low grade of mild steel.
All threads on the bars are double checked and are greased with WURTH corrosion-protecting aluminium-copper paste, this will stop the track rod ends seizing in the bars at a later date.
A Drag Link Bar is the bar from the steering box to the opposite wheel, (short bar in front of the front axle).
A Track Rod Bar joins the 2 wheels together, (long bar behind the front axle).
A rough measurement of the Drag Link bar length before fitting is centre of track rod end to centre of ball joint 92.5cm.
A rough measurement of the Track Rod bar length before fitting is centre of track rod end to centre of track rod end 123cm.
