The new V4.2 GKTECH Tension Rods offer the most amount of clearance available in a tension rod while now being 0.62" (16mm) thick! Tension rods (aka caster arms) allow adjustment in vehicle castor to bring the wheels forward and increase steering response. 

In general, the more caster the better. Allowing sharper turn in and faster return to the straight position when letting go of the wheel. 

- V4.2 arms feature high quality 5/8" Teflon lined pillow ball rod ends which eliminate the flex found in factory rubber bushing offering a more direct and predictable feel. 
- V4.2 arms are manufactured from 4130 chromoly sheet with billet CNC machined ends and CNC machined 4130 chromoly adjusters. 
- CAD designed, FEA tested, CNC machined ends and TIG welded 
- V4.2 arms include offset bush spacers for even more clearance 
- Offers a total of 56mm extra wheel clearance which equates to roughly 9 degrees of additional wheel clearance. 

Vehicle Compatibility: 
- Nissan S13 Silvia 
- Nissan 240sx 
- Nissan Skyline R32 GTS-T 
- Nissan A31 Cefiro 
- Nissan Z32 300zx 

NOTE: If you require S14/S15 240sx or R33/R34 Skyline tension rods please refer to our other listing to suit.


What is the difference between your V3 range and the V4.2?
The new V4.2 arms are similar to the V3's but just a little more refined. In the case of the caster rods the new V4.2 offer even more clearance than the V3's did and are now a whopping 0.62" (16mm) thick.

Why the change?
We have a full time Automotive engineer in-house and as such we are always looking for improvement and we saw an opportunity to improve our product. There's nothing wrong with the old arms however the new V4.2's do give even more wheel clearance.

Do you sell castor arms for my car?
We only sell the items listed on our website. If it's not listed on our website, then we don't sell it. Unfortunately we don't do any custom work. Sorry

Will these fit my car?
We can only confirm fitment for the vehicles listed above under "confirmed fitment".

How long is the warranty on these arms?
All GKTECH suspension arms come with a lifetime warranty against manufacturing defects. This does not include crashes (it's pretty easy to tell the difference between a crack caused by impact as opposed to a stress fracture) and the Teflon lined rose joints come with a 1 year replacement warranty. We stock spare bearings so even after the 12 months is up we can still help with replacements, worse case scenario we use a 5/8" rose joint which is a standard size and they are readily available through your local autoshop.

Are these suspension arms legal for use on street cars?
Our understanding is that any suspension arm with a rose joint is not legal for street use in Australia. However we do recommend that you contact your local RTA for clarification/confirmation. Whether you use a suspension arm with a rose joint on public roads is at your discretion.
