Quaife 6-Speed Synchromesh Gearkit for 02A/02J Transmissions

This fantastic gearkit was developed by Quaife in conjunction with Autotech for
the 02A & 02J transaxles. Once reserved for elite "supercars", this
synchromesh 6-speed conversion will transform your VW and make spirited
driving a real pleasure. When the ratios are this close together, it's
easier to stay in the powerband, giving you on-demand acceleration and more usable
power. Performance VW Magazine wrote, "It's like gaining an extra 40 bhp."
Each Quaife 6-speed kit includes a new HD mainshaft; all main & counter
gears including reverse, 5th gear operating lever extension, and an aluminum
end cover to house 6th gear. All standard synchros, bearings, and ring
& pinion are retained in the standard transmission casing for a factory type
installation. Unlike some other 6-speed conversions (which are really just
a 6th gear add-on), Quaife gives you all 6 gears and a new mainshaft. The
advantage is stronger gears with optimized ratios for better performance.
Our tech department can recommend a final drive ratio (your original or a new
ratio) that is best suited for your car and your driving style. This kit
fits 5-speed 02A & 02J transaxles found in all Corrados, Mk3 Golf/Jetta
VR6's, B3/B4 Passats, and Mk4 Golf, Jetta, and New Beetle models.
Note: 2001> models will require some additional parts to convert
the 1-2 synchro hub to 1-piece synchros. Contact us for details.

Quaife 6-Speed Dog-Engagement Gearkit for 02A/02J Transmissions
Because it does away with the conventional synchromesh, the dog engagement gearkit is built strictly for
racing purposes only. The ability to upshift without a clutch, and the faster
shift that dog engagement can provide, can lop chunks of precious time off each lap
or stage. The high-strength, semi-helical gears run on needle rollers
on enlarged, HD shafts. It comes complete with the following:
mainshaft, main and counter gears, dog rings, ring & pinion, end cover, and
required linkage parts. Available with a choice of two 5th and 6th ratios,
and your choice of four different final drive ratios.

Although the condition of the original gearbox will ultimately determine what actually needs to be replaced when performing
a 6-speed conversion, you should consider any part for replacement just as if you were doing a standard 5-speed rebuild. However,
things such as a complete gasket set, the 2nd gear synchro ring (the one that takes the brunt of hard driving), and
new mainshaft bearings are just about a sure thing. www.autotechparts.com can supply most replacement parts you may need.
