Belt Tensioner for 17 F3L

[GaryinWI]

I’m ready to order a belt tensioner. Appears Lamonster has the modified BRP model and SlingMods has the SpyderExtras. Price aside, I like the idea of the bigger roller/bearings on the Lamonster setup. The idea of losing the roller and asking out belt scares me.

I would appreciate hearing everyone’s experiences good or bad. Thx.

I installed the Lamonster roller/bearing upgrade on my 2019 F3-S. Have about 2k miles on it. Much beefier/substantial than the OEM roller. Nice upgrade..

I have Lamonsters also on my 18 F3L. Over 8,000 miles on it and still works great.

Our roadster renovations 1 million mile belt tensioner failed and ruined the belt at 50,000 miles. Told doc. He owes me a belt and a refund. Replaced the belt, and with a few attempts, found the perfect tension. No belt tensioner for us!
Of the bunch, I like Lamont’s best. Since most folks will never see 50k in 2 years, it looks to be the best of the bunch.

still got docs on. about 15000 miles. still seems tight. have 1 replacement roller and spring laying around.
will probably get lamont roller for the brp setup that i bought a couple of years ago.

I don't think he ever guaranteed it to last one million miles. What he wrote one time was that all the tensioners installed added up to over one million miles. Don't expect to ever get the refund and replacement. He and his business seem to have totally evaporated from the internet and from his home town.
