Overall I like Redline products- I've used the 20-60 engine oil and HD SKHprf trans oil on several bikes, and even their syn diesel oil in my Cummins with very good results.
When I replaced the 5psd trans on my 06 FLHX with a Baker DD6, at the time of install Baker recommended using Redline HD shockproof so I found some and put it in- I had previously been running BelRay for 11,000 miles with no complaints.
