V8 Engine Conversions

Kingsley totally re-engineers the original Rover V8 engine to add reliability and efficiency whilst increasing performance.

We offer Kingsley re-engineered engines in two variants, 4.6 litres and 5 litres with fuelling via either a modified, more efficient version of Lucas 14CUX fuel injection or via twin SU carburetors.

Kingsley re-engineered engines are guaranteed for 5 years, with unlimited mileage when serviced by Kingsley annually or every 6000 miles (whichever is sooner). Engines that have not been serviced by Kingsley carry a 12 month or 6,000-mile warranty (whichever is sooner).

Automatic Gearbox Conversions

We install ZF 4HP22 or electronically ZF 4HP24 automatic gearboxes mated to your Puma TDCi, TD5 or V8 engine — all fitted in either NAS Style factory centre consoles or custom centre consoles — please call to discuss your requirements.

Running Gear

Transform the ride quality and driveability of your Land Rover Defender with Kingsley Defender running gear upgrades.

Upgraded Suspension Package

Kingsley has developed, in conjunction with a leading shock absorber manufacturer, custom-built high-performance dampers to suit the Defender and to compliment our own custom springs, which lower the car by 1.5″ and include uprated anti-roll bars in various thicknesses to suit your application and requirement.

Heavy Duty Driveline and Uprated Differentials

Our 24 Spline HD shafts are made from 4340’ alloy steel. We have also made some design improvements to remove the stress concentration which typically causes failure at the diff end, this allows the shaft to flex along its length absorbing much of the shock loads.

TrueTrac Limited Slip Differential

  • Fully automatic — needs no driver input
  • Totally transparent on the road, i.e, no unwanted adverse effects
  • Only comes into play when one wheel loses traction, i.e, a difference in wheel speed
  • Enhances the traction control as it multiplies the bias load created by the braking effect of the traction control
  • Only available with 24 spline driveshafts

Defender Big Brake Kit

Kingsley Big Brake conversion removes the challenge of trying to stop a breathed upon or quicker Defender.

The kit consists of a massive pair of 6 pot front calipers with new larger brake rotors and a pair of 2 pot calipers with drilled discs, an uprated master cylinder, slave cylinder, and depending upon your model year a different shuttle valve, T pieces, reducers for the rear lines and four flexible hoses.

The calipers are made from solid billet which is then powder-coated in black and uniquely engineered to fit behind all Defender wheels including the Rostyle wheel.

They provide the ultimate fast road​driving stopping’ dependability.

Defender Wheel Upgrades

Tubeless 8J Wide Rostyle and 8J Wide Wolf Wheels

Dinatrol Underbody Protection

Rust is Kingsley’s nemesis so when I met a chap called Ian of Rustbusters, I knew that I had found a kindred spirit. Ian is obsessed with the prevention and cure of rust and I knew that Kingsley should follow his well-proven system and purchase all of our rust-proofing products from Rustbusters. See our rustproofing process page here.
