What Defender Owners Say

"Had the Explorer package done on my Defender 110. Terrain response 2 2 and Wade Sensing make a huge difference off-road. The whole process took under an hour and cost a fraction of what the dealer quoted."

James R. — Defender l663 retrofit modifications 110 D300

"Went for the Ultimate package with the our power upgrade services. The D250 feels like a completely different vehicle now. Throttle response is instant and the extra torque is addictive. Highly recommend."
