Includes:
2 x Trundles UCA's pre-fitted with OE style rubber bushes
2 x Heavy Duty Ball Joints pre-fitted to the control arms
2 x Trundles Ball Joint Dust Caps
2 x Dust Cap sealing O-Rings

These UCA's are designed to fit:
- Nissan Navara D40 Spanish built models with VIN# starting with VSK with the YD25 engine

- Nissan Pathfinder R51 Spanish built models with VIN# starting with VSK with the YD25 engine

- Nissan Navara D40 Thai built models with VIN# starting with MNT with the YD25 engine

- Nissan Navara D23 NP300 Thai built models with VIN# starting with MNT

Please Note: Suits up to 60mm Lift with 2" Extended Strut. D40 models with 1 OE Camber bolt will not achieve factory camber specs with arms.

Features standard to the Trundles UCA’s are:

- 3 degrees of fixed Caster correction This has been identified as the perfect amount of correction required for lifts ranging from 30-70mm. By providing a bulk, fixed amount of caster, this offers the ability to utilize the factory adjustment to fine tune the caster required for the vehicles lift, with the UCA not being the limiting factor for increased droop relative to the other components.

- Camber change to meet OE spec, if your application requires increased camber, we can offer offset bushings to provide more camber.

- Clearance to larger aftermarket wheels & tyres – we often see larger than standard size tyres with wheel offsets having clearance issues to the OE UCA, our UCA’s minimize this as much as possible.

- Clearance to suspension components & chassis – a large number of OE UCA’s hit the coil or the chassis mounts during the suspension travel limiting the amount of travel you can achieve, with revised bends and clearances identified the UCA’s will not contact the strut or the chassis limiting travel unless specifically designed to do so.

- Fixed position ball joint – UCA’s do not use an adjustable ball joint. With a fixed location ball joint we are able to offer OE specification for the ball joint itself.

The position of the ball joint housings have been rotated to ensure the ball joint is not the limiting factor with maximum down travel. We have specifically chosen a fixed ball joint for a number of reasons – in off road applications the ball joint receives a large amount of “bump” loads, which over time can either knock an adjustable ball joint out of position leading to increased tyre wear due to a change in caster. Changing from a fixed ball joint mount reduces the structural integrity of the mount and the mounting platform of the ball joint, with any remote traveling we need to ensure strength and reliability is not compromised.

There will never be a need to adjust or re-adjust your caster once established with the control arms as the ball joint cannot be knocked out of position.

- Maintain OE specification ball joint & bushings – regardless of where you may go, if you need to replace a ball joint or bushing you can use genuine replacement parts or aftermarket OE specification replacement items, regardless of how remote you are at home or abroad.

- Ball joint binding – Often we see the ball joint limiting the amount of down travel because the OE ball stud hits the side of the ball joint housing, this creates a stress point on the ball stud creating an environment for potential terminal failure of the ball joint, it also limits the amount of down travel possible when used in conjunction with aftermarket suspension and longer shock lengths.

- Securing ABS lines – we incorporate tabs and mounts where practical so the OE lines can be secured discreetly where possible, reducing the potential of sticks and other debris from damaging the sensitive lines.

- Increased strength compared to the OE design – The design of the Trundles arms have shown with the use of FEA to be much stiffer than the OE arms, providing the driver with increased handling and response when the Trundles arms are fitted when compared to the OE arms, this is illustrated by the amount of deflection the FEA results have provided, with 3 times less deflection in the Trundles UCA’s.  Does this rigidity negatively transfer to the vehicle? – No, because the Trundles UCA’s use OE Rubber bushings, any NVH (Noise, Vibration and harshness) is absorbed in the rubber bushings before it makes it way to the chassis, you may find an increase in wear in the bushings which is directly related to how you drive the vehicle, the bushings are a consumable component of any vehicle, however you should expect years of trouble free service before you should need to replace the bushings.

- Heavy Duty Long life Ball joints – A specially redesigned the OE ball joint results in a more robust design, due to the nature of the application the 4wding community requiring a serviceable component. Subsequently Trundles UCA’s have a ball joint that is manufactured in the “hard to hard” style with a locating nylon disc that the ball stud terminates against, grease is pumped into the assembly through the top keeping everything lubricated and keeping any potential contaminants out of the boot region. The ball studs and seat area of the housing are all heat treated forming a hardened surface with the purpose of long life and limited wear.

- Dust Cap – Trundles UCA’s that utilize a press in ball joint feature a machined alloy dust cap, black anodized incorporating the Trundles logo, to deter corrosion. The cap position results in creating a sealed housing to protect the greaseable top section of the ball joint from the elements such as water, dust & mud.

- Finish – All arms are sand blasted upon completion and E coated black for a durable discreet finish. E coating is the same process the vehicles manufacturer used for the original equipment you are replacing.
