Tech Tip 1: Do not ever force the adjuster knobs. This could damage the adjuster and cause the strut to not adjust.

Tech Tip 2: Do not use the strut as a droop limiter during operation as this will damage the strut.

Tech Tip 3: Vehicles with front ends that leave the ground during operation should use limiting straps.

Please Note: Before dismantling anything on your car, lay a straight edge across the top of the fenders and measure down to the top of the strut shaft. Try to match that dimension when you install the strut with the spacers.
