Choose to buy either a link bar & nuts kit only or select the drop down options list to include rod ends, spacers & dust boots in the pack.

Turnbuckles - 5/16"

McGill Turnbuckle Links are internally threaded right hand at one end and left hand at the other to make them easily adjustable in length without having to remove the bolts from the rod ends. These linkages are manufactured to be within excellent tolerances. These are commonly used for motorsport when making links such as drop links, adjuster bars, steering arms etc.

Available in the following sizes:

70mm - Adjustment range 120mm - 150mm centre to centre distance.

100mm - Adjustment range 150mm - 180mm centre to centre distance.

120mm - Adjustment range 170mm - 200mm centre to centre distance.

150mm - Adjustment range 200mm - 230mm centre to centre distance.

200mm - Adjustment range 250mm - 280mm centre to centre distance.

250mm - Adjustment range 300mm - 330mm centre to centre distance.

300mm - Adjustment range 350mm - 380mm centre to centre distance.

- Outer Diameter: 12mm
- Made from Carbon Steel 1045 (C45) *
- Zinc plated to give excellent resistance to corrosion.
- Ideal for use as gear linkages, anti roll bar drop links, 4 link kits, ladder bars, steering arms, castor arms, compression struts, watts linkages etc.
- Save time by using these in place of drilling and tapping out solid steel. 
- CNC precision machined.
- Flat spanner size central section for easy adjustment. 
- Manufactured to within excellent tolerances.

Why use a turnbuckle?

- Save time and money by using these pre-made link bars.
- Attractive looking product, nice finish.
- No need to remove bolts to adjust the linkage length, just simply turn the link bar to either extend or shorten the linkage.
- Manufactured in a range of lengths to accommodate most requirements.

* Carbon Steel 1045
C45 is a medium carbon steel is used when greater strength and hardness is desired than in the "as rolled" condition. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Turned, ground and polished. 
Physical properties (average values) at ambient temperature 
Modulus of elasticity [10(3) x N/mm2]: 205 
Density [g/cm3]: 7.85
Specific heat capacity[J/g.K]: 0.48


Rod Ends

Economy

CM Economy Series Rod End
(CMR5 - 5/16" UNF Right Hand Male & CML5 - 5/16" UNF Left Hand Male)

CM Range - Ideal for Budget Motorsport, Marine and Industrial Applications.

BALL: 52100 Bearing Steel ~ Heat Treated ~ Hard Chrome Plated ~ Precision Ground
BODY: Carbon Steel ~ Protective Coated ~ Corrosion Resistant
EXCLUSIVE FEATURES: No Maintenance Required ~  No problems of PTFE Liners popping out under high loads





Ultra High Performance

XMM Racing Series Ultra High Performance Rod End
(XMR5 - 5/16" UNF Right Hand Male & XML5 - 5/16" UNF Right Hand Male)

McGill XMM - Racing Series Ultra High Performance Racing Series range features a loaded slot style of rod end that was introduced to the market in 1995. The body is machined with a significant groove going all the way around the interior of the body. The ball is then inserted into the machined slot and a Teflon®/kevlar® material is injected. Serving as a liner to keep dirt and debris out, the kevlar also lubricates the ball. In addition to providing added strength, the injection moulded race also won’t “pound out” like traditional PTFE (Teflon®) liners, increasing the longevity of your rod ends. The body is heat treated and is made from Chrome Molybdenum for excellent strength and corrosion resistance. This is simply the best rod end design for most motorsport applications. Chrome-Moly Steel with Teflon®/kevlar® injection moulded liner.

XMM Range - Ideal for Motorsport and Marine Applications.

BALL: 52100 Bearing Steel ~ Heat Treated ~ Hard Chrome Plated ~ Precision Ground
RACE: Injection Moulded kevlar Reinforced with PTFE ~ Self-Lubricating ~ Self-Sealing
BODY: Chrome Molybdenum ~ Heat treated ~ Corrosion Resistant
EXCLUSIVE FEATURES: Thicker Body for Increased Tensile Strength ~ High Radial Load Capability ~ Metal to Metal Support for Heavy Shock Loads



Nuts

5/16" UNF Half Lock Nuts - Mild Steel - Bright Zinc Plated
(JNR5 - 5/16" UNF Right Hand Thread & JNL5 - 5/16" UNF Left Hand Thread)
These are commonly used for motorsport when securing rod ends to link bars. As the nut is half the thickness, it allows for maximum adjustment.

- Ideal for securing linkage bars in place on the rod end to prevent rotation of the bar.
- As the nuts are half the thickness of standard nuts, a finer adjustment can be made as the rod end can be screwed further into the link bar.
- Mild steel, CNC precision machined.
- Protective coated for corrosion resistance (Bright Zinc Plated).


Spacers

5/16" Misalignment Spacers - Zinc Plated
(SPCR5(QTY:4) - 5/16" Inner Diameter) 

- Ideal for use as a spacer with all types of rod end.
- Retain the full misalignment angle of the rod ends by using these tapered spacers instead of using washers.
- CNC precision machined.
- Tapered design allows for maximum misalignment.
- Protective coated for corrosion resistance (bright zinc plated).
- Perfect for all forms of motorsport.




Sealing Boots

RODOBAL Rubber Dust Protection Boots
(SEAB1 x2 - 5/16" Dust Protection Boot)

- These boots are a very tight fit on the rod ends, offering great protection from water, dirt, etc.
- Patented design, one piece moulded ensures no seams or entry points & extends life from rod ends.
- Suitable for use with spacers or reducers
- Constructed from thick high quality Neoprene gives excellent durability and the best protection to your rod ends.
- Ideal for used in Autograss & Shale circuit racing.
- Boots can be packed with grease if desired.
- Allows free rotation of the ball, no area of performance is affected.
