Pushrods & Pushrod Checker

We include a pushrod length checking tool in each kit for measuring proper pushrod length. Because brands of lifters and rockers require different pushrod length.

Rockers

We offer many style rockers to choose from. Rockers that will work for these kits include stainless steel or aluminum from brands such as Comp, Scorpion, PRW, Crower, and more.

We recommend 1.5 ratio rockers so that pushrod slotting is not neccessary.

Valley Pan & Distributor Gear

Hydraulic Roller Lifters require aftermarket valley pan such as the TPP-TP-041S

Requires polymer distibutor gear such as BOP-PDG37 or BOP-PDG38
