Suffolk Jaguar XK120

Led by increasing customer demand, we are now pleased to offer the remanufactured Suffolk Jaguar XK120. This stunning car had many successes from Daytona to Le Mans and once many competition events in period. The Jaguar XK120 was the car which established Britain as a maker of great sports cars. The XK120 car retained many of the elegant pre-war design features from the SS100.

The Suffolk Jaguar XK120 has been completely remanufactured and re-engineered to be the ultimate classic Jaguar XK120 for the modern world. The rolling chassis is original and restored. The car has uprated suspension, steering and brakes, and even electric power steering. We have made a new aluminium body, hand-wheeled in Great Britain.

The car has a 4.2 litre engine and 4-speed overdrive gearbox with all the Suffolk reliability and performance upgrades.

Inside the car, we have achieved 3 inches extra space rear of the seats by changing the rear bulkhead and hood assembly. The floors have been lowered 1”, the front bulkheads are completely relocated and a new pedal box 4” forward of the original means there is over 8” of extra space compared to an original car.

We have designed and made a bespoke interior to the highest standards, with double stitched two-tone leather door cards, hand made heated leather bucket seats, and a centre console/armrest that conceals storage, 12v power and a cup holder.

The idea behind this commission was to incorporate as many modern features and make the finest appointed XK120, whilst still keeping the cars valuable period aesthetic. So many cars have been rebuilt in the past with inappropriate ‘catalogue’ parts, leading to a car that appears cluttered and obviously modified.

Our rebuilding project starts with an original Jaguar XK120 – these cars can still be found in unrestored condition, providing the basis for this wonderful new Suffolk built car.

We remove the body, and strip down and catalogue all parts of the car, inventorising all the original items which will need replacement, and orchestrating the manufacture of the parts which will replace the inferior original items – giving the Suffolk Jaguar XK120 it’s unique features.

Upon receipt of an order we will begin the strip down and cataloguing of the original car. Essential original items are saved such as the chassis and various original XK120 parts. The chassis is then stripped of all paint and rust and fully inspected, checked for straightness and any restorative works carried out. Also at this time, the additional bracketed required for our special in house Suffolk made parts are added.

Once complete, the chassis goes away for powder coating in satin black.

When the chassis returns, it is time to begin assembly, with the front suspension, disc brakes and rack and pinion steering.

Then, the 240BHP 4.2 litre engine and all synchromesh overdrive Jaguar gearbox are fitted. At this stage the whole assembly is given a 4 wheel laser alignment and shimmed as required for the desired castor, camber and toe settings.

Shortly after this the body will arrive with us for trial fitting. Critically, this body is not one that is made by inferior ‘super forming’ or made using cheap labour overseas. It is made in the UK by real artisans who have a genuine passion for the product, and is made on Suffolk’s own body jig and tooling. It is not available elsewhere else on the market.

Our rear bulkhead and pedal box arrangements are such that there is over 8″ extra room inside the car, now allowing drivers of any height to enjoy an XK120 in comfort – this was a big shortcoming and complaint of the original car.

After checking and shimming of the bodywork it is removed and is sent to the paint shop on our body jig to be painted in the customer’s choice of colour. At Suffolk Sportscars you are not restricted to any colour palette and we can take colours from anywhere in the world. We can also assist you in commissioning your own colour scheme or taking inspiration from the world around you

When the painted body is returned, the fitting up of the car can begin. The bespoke pedal box uses some C-type parts, and a remote servo, and hidden fluid reservoirs. The electric power steering unit and adjustable column, an alternator built into a dynamo body, remanufactured gauges, a new wiring loom and upgraded lighting all make the car safer and more reliable to use.

Even auxiliary charging and a hidden storage compartment in the centre arm rest are standard. A hidden bluetooth audio system is also available. This is a classic car that is 100% 21st century ready, and can be used on a daily basis in today’s modern world.

Inside the car, heated and fluted leather bucket seats, styled after the original bench are handcrafted in our own workshops with foam cushion densities to suit you. They are adjustable on sliders and a hidden storage compartment is set into the arm rest.

A full tonneau cover with zip, a full hood, and side screens are included and made in mohair to match, or contrast the car’s colour scheme. Alternatively on Fixed Head Coupe examples, one can specify the wood trim and headlining colour, or opt to trim the cockpit in full leather in the style of the roadster.

We are pleased to be able to build a Suffolk Jaguar XK120 remanfactured in aluminium to a customer order and offer a 12 month guarantee against the specific failure of any mechanical part. We undertake to supply replacement parts on an exchange basis only.  Cars requiring labour as part of their 12 month guarantee can be returned to our works at the customer’s cost, so that the repair can be carried out for free.

Completed cars are supplied with the latest British Department of Transport Vehicle Registration Document V5C and a 12 month MOT certificate.

Each Suffolk Jaguar XK120 retains its original 1950s historic registration as it is ostensibly an original classic car. This can simplify registration regulations in certain countries.

We have exported completed cars to most European countries and also to the USA, Canada, South Africa, Australia and New Zealand.

Catalytic converters are not necessary but can be fitted where local regulations require.
