Description
1 x Heavy Duty STEEL EN8 Steering Drag link Bar, front bar in front of axle (SUMOBARS)
Part No:- SUMO-HD-830, Defender Drop Arm Conversion Bar, HD Steel
This bar is used with a Discovery 1 Straight Drop Arm to make a Drop Arm Conversion Kit, this will not fit with the standard Defender Swan Neck Arm, the standard Swan Neck Arm uses a SUMO-HD-740.
Picture 3 shows the two different Drop Arms, the lower one is the Straight Discovery Drop Arm that is needed to do the conversion, as you can see it uses a track rod end and not a press in ball joint that is difficult to replace. We have a Full Defender Drop Arm Conversion Kit available HERE.
Weight:- 5kg
Manufacturer:- Gwyn Lewis 4×4 SUMOBARS, these are made in the UK not cheaper imports.
Fits:- Defender 90/110/130 Right Hand & Left Hand Drive (When fitting with a Discovery 1 Straight Drop Arm)
These are our Solid Heavy Duty Steel Steering Bars, (SUMO-HD) they are 30mm solid EN8 Steel bars, designed to be used by all, on and off road.
The Kit includes:-
1 x SUMO-HD-830 Heavy Duty drag link bar (front bar) & 2 Full Lock Nuts left & right hand thread.
No Track Rod Ends are supplied with this bar, you will need 1 x Right Hand and 1 x Left Hand. You will also need a Steering Damper Mount and your own Discovery 1 Drop Arm to complete a full Drop Arm Conversion Kit.
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.
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, 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. 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 rough measurement of the Drag Link bar length before fitting, from centre of track rod end to centre of ball joint is 92.5cm.
A Track Rod Bar joins the 2 wheels together, (long bar behind the front axle). A rough measurement of the Track Rod bar length before fitting, from centre of track rod end to centre of track rod end is 123cm.
