When it comes to our 4×4 vehicles, handling and suspension are just about everything. So, it stands to reason you’d want to do everything within your power to improve your suspension and this can be done by either purchasing a new suspension kit or upgrading your existing suspension kit. One of the most practical and affordable options is to purchase greasable shackles for your suspension, though it is more likely to be beneficial in the long run if you upgrade your shackles alongside new springs.
What are greasable shackles?
Non-greasable shackles are, as the name suggests, not lubricated. This means that, over time, they will corrode and destroy the leaf spring bushings. It’s these bushings that stabilise the leaf springs and worn bushings can cause destabilisation. This leads to a drive that wanders all over the road and could be completely unusable under heavy braking conditions, particularly if your 4×4 is carrying a heavy load.
Why should I be using them?
Greasable shackles are equipped with grease nipples that allow leaf spring bushings to be kept lubricated at all times. This allows for better spring travel and articulation off-road. This in turn improves bush life and dramatically reduces spring fatigue.
The telltale sign that might suggest you need to install greasable shackles in your suspension is that your bushings have begun to show serious signs of wear and tear.Shackles are often overlooked when it comes to upgrading suspension and you will be paying slightly more for greasable shackles but it’s an upgrade you’ll be glad you went through with. You’ll get more flex for the rear axle and you’ll notice a quieter ride too, especially on-road driving. Remember, however, that you’ll need to keep them greased!
