MK1 Cortina Reverse Eye Single Leaf Springs (CS062*G)

Typically when lowering your Cortina on Leaf Springs you would have to de-camber the springs or run with lowering blocks which from an engineering viewpoint is not an ideal practice. De-cambering the Leaf Springs to achieve the desired ride height means the rear shackle runs out of travel, the Leaf Spring can then become coil bound under compression which will make the car unstable and handle in an unpredictable manner due to the spring running out of travel.

Retroford has designed and developed a brand-new single Leaf Spring that will alleviate all the problems associated with de-cambering your original springs. By running the eyes reversed on the Leaf Spring it allows the spring to retain the correct camber and have a full range of travel.

Unlike the original Cortina Multi-Leaf Spring, the brand new Retroford Single Leaf Spring has a parabolic tapered design giving better axle location and improved reliability.

The brand new Retroford Single Leaf Springs are a direct replacement for the original standard Cortina springs and can be used with the original rear shackles or with the brand-new Retroford Rear Leaf Sping to body Mounting Shackles (CS059*G).

Due to the variation in ride height between the many different original Cortina springs, we cannot give a definitive minus figure that these Single Leaf Springs will lower your car by. Based on you running a 185/60/13 size tyre and the Retroford Diff Nose Angle Correction Wedges (CS063*G) the centre of the rear wheel arch will be approx. 465mm From the floor. Please scroll through the product pictures above to see the ride height.

Note – Failure to use without diff correction wedges (CS063*G) will result in prop shaft UJ misalignment.

MK1 Cortina Diff Nose Angle Correction Wedges (CS063*G)

Typically when you lower a leaf-sprung car it causes the rear axle to sit higher in relation to the gearbox, this will cause the prop shaft UJ to be misaligned which can result in vibration and premature UJ failure. To correct the misalignment Retroford has developed a set of Diff Nose Angle Correction Wedges – Please see additional product pictures above.

The Diff Nose Angle Correction Wedges have a 5-degree angle and are machined from billet aluminium
The wedges should be fitted with the larger end of the wedge towards the rear of the car
For use with Retroford Cortina Reverse Eye Single Leaf Springs (CS062*G)
The unique design incorporates an inbuilt axle location peg
Sold as a pair

Note – If you are not using these wedges with the Retroford Cortina Reverse Eye Single Leaf Springs (CS062*G) then they may need to be modified.

MK1 Cortina Heavy Duty Axle U-Bolts (Set of 4) (DRT039*G)

Axle U bolts are often overlooked when modifying a RWD car. The U-bolt’s job is to connect the axle to the leaf springs. Most aftermarket U-bolts are fine for standard cars but as soon as they are used aggressively or with cars with more BHP they have a tendency to stretch and bed in and will need to be re-tightened periodically. The 4 main issues of most aftermarket U-bolts are choice of material, thread size, bend radius accuracy and lack of flat on the bend radius.

Retroford has developed an uprated U-bolt to combat all these issues.

They feature:

Oversize 12mm thread (but still fit std leaf spring retaining plate).
Hot forged to create a flat face where the underside of the U-bolt meets the axle tube gives far more surface area and a more positive axle location.
Made from high tensile steel.
Accurate bend radius.
Comes with nuts and washer.
Can be used with Retroford heavy-duty rear leaf spring plates (DRT040*G) and also Retroford diff nose axle correction wedges.
Sold as axle an axle set = 4 x bolt U-bolts, 8 x washers .8 x nuts.
Available exclusively from Retroford.
Can be used without lowering blocks or a maximum of 1” lowering blocks.
Not suitable for 2” lowering blocks.
