XRAY T4 Mid-Motor Conversion Kit compatible with T4 '17-'19 - JR-XT4CK by Jazrider  [JR-XT4CK]

Mid-motor layout conversion for the T4 series

This mid-motor conversion kit adapts the XRAY T4 '17/'18/'19 platform to a mid-motor layout to change mass distribution and provide an alternative baseline for tuning. The kit is intended as an RC-scale upgrade to experiment with balance and handling characteristics without altering the original chassis geometry beyond the conversion components.

Installation requires basic disassembly of the T4 drivetrain and mounting points to relocate the motor toward the centre of the chassis. Typical tasks include removing the stock motor plate, fitting the conversion brackets, re-routing the driveline alignment, and confirming gear mesh and clearances. Use appropriate hex driver sizes and verify all fasteners are secure before testing.

On the track, a mid-motor layout shifts weight distribution, affecting traction, turn-in, and throttle response. Expect changes that require iterative adjustment of suspension, shock oil, and differential setup rather than plug-and-play results. Use this kit as part of methodical setup changes to compare front- vs mid-motor behaviour in lap-time or handling tests.

Use this conversion to methodically test mid-motor geometry on your XRAY T4; allow time for progressive setup changes and verify driveline alignment after fitting.
