Does Thump Racing still make a Single Bolt Tensioner with a 76mm Pulley suitable for use on a Marauder?

If so please advise the part number, I cannot find it on their website.

If not can anyone recc a replacement?

I have a Vortech with 8 rib belt.

Thank you.

IIRC Billy, the thump unit would hit the Vortec bracket and require having Thump re clock the pin and/or having to trim a small amount off the bracket.

I would just call them directly either way. I sure as hell thought my solid tensioner would give me issues but not a peep. Unfortunately that is only an option on cog set ups.

Thank you, I will contact Thump.

With the 8 rib the S/C bracket is offset enough to clear the tensioner.

Yes initially I had the single bolt tensioner it cleared the bracket as I had to space the Vortech bracket to align with the 8 rib setup , but I went to the three bolt tensioner and front cover and I wouldn't recommend the single bolt unit with a Vortech , the bracket covers the bolt slot the adjust the tensioner and it becomes a nightmare just to change the belt!
