★★★★★ We fit these for customers every month
Workshop customer · Christchurch · Example review

Order before 2pm, on the bench next morning. Preload sorted so we do not see them back. Saves us a hoist for a week every time.

★★★★★ Sorted the clunk
Dave P · Nelson · Example review

Rang the team first to check it was the right one for my rego. It was. Fitted by my local mechanic, no more clunk on take off.

★★★★★ Quiet as new, swapped it over in an afternoon
Mark T · Timaru · Example review

Had the classic whine at 80. Diff turned up next morning, swapped it over myself with the fitting guide, return label was in the box. Three weeks on and dead quiet. Core charge came back inside a week.

Reply from the Gearhead Diffs teamCheers Mark, glad the guide did the job. Thanks for getting the core back quick.
