The new V5 GKTECH Caster Arms offer the most amount of clearance available in a caster rod while now being 16mm thick AND now have on-car adjustment! 

Caster arms (aka tension rods) 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.

- V5 arms now feature on-car adjustment to make alignments a breeze! 
- V5 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.
- V5 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
- V5 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.

Gktech castor arms

I bought Gktech castor arms for my R32 Gtst hillclimb/super sprint car after watching a video on the product and was keen on the idea of additional caster angle.
I am wrapped after the fitting and having an additional 2degrees of castor over my old ajustable arms. The additional clearance was not required as my sway bar is in the way, the sway bar was not a factory item and was purchased to clear a larger sump.
I have sine replaced all the rear arms and had an alignment and am looking forward to a run this weekend

Great Product, Easy Install

Got these for my r32 to adjust caster and the install video made it super easy to put in. Wish the supplied nut and bolt weren’t different sizes but that’s just a pet peeve. Car drives noticeably better now.
