With many classic cars getting hold of original parts is becoming increasingly difficult with supply dwindling or worse, parts being discontinued altogether. 
The factory KONI rear shock absorbers are no exception. The rubber mounting bushes wear and perish, leading to vague handling or unwelcome knocks and clunks so we have added these Rear Shock Lower Bushes to the range. 
Made in our classic Grey 95A durometer material to retain that OE look, our bushes help to restore handling feel, with longevity backed by our Lifetime Warranty. They are also the perfect accompaniment to our PFR57-413 Rear Shock Upper Mounting Bush.
Replacing your car rubber suspension bushes with Polyurethane Suspension Bushes will give you:

• Better road holding
• Constant steering geometry
• Increased tyre life
• More responsive steering
• Longer service life of suspension components

Rear shock tower reinforcement.
Sold per kit, 1 kit required per car.

Fits:
Porsche 911 - 1965 to 1972

✓ Laser Cut – Fits the profile of the shock tower perfectly.
✓ Strong – Solidly ties the towers and cross-member into unibody box sections and inner wheel well. Distributes the shock loads properly and reinforces the entire section.
✓ Holes – Great appearance and convenient routing of hoses and wires.
✓ Weld from one side – Fully seam weld without removing rear firewall.
✓ Light Weight – Properly engineered to distribute loads, not 'over engineered' with excess material and weight.

When converting the 911 torsion bar rear suspension to coilover, the rear shock towers should be reinforced. Coilover springs introduce loads the towers were not designed to handle. Without reinforcement, cracks can develop over time – most frequently between the crossmember and unibody box sections.

Our reinforcement kit strengthens this vulnerable area and properly distributes coilover spring loads.

Rear Shock Tower Reinforcement
Our brackets make it easy to get a professional result, saving you the time and guesswork cutting your own.

This kit requires welding for installation.
