SR>RB Gearbox Adaptor Plate

SR>RB gearbox adaptor plate

Back by popular demand is our original Garage-D SR20>RB25 gearbox adaptor plate. 

With SR20 gearboxes notorious for breaking above 300bhp, these adaptor plates allow bolt on fitment of an RB25 large casing gearbox which are generally rated to 500bhp+. Over the years we have sold these adaptor plates literally all over the world, these are the only ones with correct fitment and OEM dowel location.  

Zinc coated and GARAGE-D branded adaptor plate contains fitting kit and instructions. Additional parts required for the conversion:

- RB25 gearbox

- RB25 propshaft (needs shortening for S14/S15 or end swapped for S13 due to carrier bearing)

Full packages including gearboxes available aswell as propshaft modification services (all parts available separately also). For more information on this conversion please contact us direct at: or +44 (0) 1923 251588
