In keeping with the tradition of American V8s powering the Allards, the Allard J2X® MkIII chassis is designed to accommodate new emission-compliant GM engines (Cadillac or Corvette), as well as the latest MOPAR Hemi fuel-injected V8s. A number of power ranges are available to suit the owner’s preference and driving ability.

 Transferring over 400 lbs/ft of torque to the back wheels is a task that the Tremec TKO 5-speed transmission does very efficiently. This fully synchronized competition grade unit has a fifth-gear overdrive to ensure effortless cruising and fuel economy. Automatic transmissions are also available for GM and Hemi power plants.

With some similarity to the original deDion rear suspension, the Allard J2X® MkIII rear suspension unit includes a tough 9” centre-section housed in a cast aluminium alloy block. The half-shafts are of hardened steel with equally strengthened universal joints.

Exceptionally robust shifting and control

The most versatile 5-speed around


Far and away the most versatile 5-speed on the market, the TKO offers an impressive array of flexibility features – including multiple shifter locations, mounting configurations, gearing options, and speedometer pickups (electric and mechanical).

Serving up 600 lb-ft of torque capacity, along with confidence-inspiring shifts and fuel-saving overdrive, the TKO offers an ideal blend of brute strength and street manners – which may be why it’s the manual transmission behind more boulevard-bruising street machines and sportsman race victories than all of it’s competitors combined.

  • 5-speed, top-loader
  • overdrive – for fuel economy
  • fully synchronized
  • competition grade
  • high strength aluminium housing
  • high torque capacity (500 ft/lbs)

The rear of the J2X MkIII

A most smooth and comfortable ride


With its 12” cross-drilled disk brakes located next to the differential, the reduction of unsprung weight on the rear wheels provides a smoother ride and minimal loss of traction on uneven surfaces. The front and rear independent suspensions can be adjusted to the driving task at hand with four fully-adjustable coil-over billet aluminium gas shocks. The front suspension consists of tubular upper and lower heavy-wall seamless steel unequal A-arms with fully-adjustable caster and camber. Similar to the back, braking is handled with 12” 4-piston Wilwood disc brakes. Steering is done through a rack & pinion unit.
